An In-Depth Guide To Electro Princess, Fischl


Official Description

A mysterious girl who calls herself "Prinzessin der Verurteilung" and travels with a night raven named Oz. Currently serves as an investigator in the Adventurers' Guild. Through her unique abilities, eccentric character, and (while she would never admit it herself) hard work, Fischl has become a rising star among the Adventurers' Guild's investigators, earning the recognition of all.

In-Game Character Profile

Fischl is the Prinzessin der Verurteilung who arrived here after being exiled from the otherworld, "Immernachtreich." She "observes and weaves the threads of fate" together with her talking night raven familiar, Oz. Owing to reasons she cannot and Oz will not explain, Fischl now serves the Adventurers' Guild as an investigator.

Fischl is an electro character and a bow user. She is a top-tier support and DPS character. In this guide, we will explore various Fischl builds, including team compositions, best weapons, and best artifacts.

To start off, Fischl can be played both as a DPS and a support character, so our guide will be divided into two parts: DPS Builds, and Support Builds. But first let’s explore her talents and constellations.

Exploring Fischl's Abilities


 Talent TypeTalent NameOfficial Talent DescriptionThoughts
Normal/Charged AttackBolts of Downfall

Normal Attack: Perform up to 5 consecutive shots with a bow.

Charged Attack: Perform a more precise Aimed Shot with increased DMG. While aiming, the dark lightning spirits of Immernachtreich shall heed the call of their Prinzessin and indwell the enchanted arrowhead. When fully indwelt, the Rachsüchtig Blitz shall deal immense Electro DMG.

Plunging Attack: Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.

Pretty normal huh. It does get a bit more complicated with constellations though.
Elemental SkillNightriderSummons Oz. The night raven forged of darkness and lightning descends upon the land, dealing Electro DMG in a small AoE.

For the ability's duration, Oz will continuously attack nearby enemies with Freikugel.
Hold to adjust the location Oz will be summoned to.
Press again any time during the ability's duration to once again summon him to Fischl's side.

Depending on your build this will be your main source of damage. You most likely will be building Fischl to make Oz a God.

Just to clarify, pressing E again will bring Oz to Fischl's location, if you're confused about that.

Elemental BurstMidnight PhantasmagoriaSummons Oz to spread his twin wings of twilight and defend Fischl. Has the following properties during the ability's duration:
  • Fischl takes on Oz's form, greatly increasing her Movement Speed.
  • Strikes nearby enemies with lightning, dealing Electro DMG to enemies she comes in contact with. Each enemy can only be struck once.
  • Once this ability's effects end, Oz will remain on the battlefield and attack his Prinzessin's foes. If Oz is already on the field, then this will reset the duration of his presence.
You become Oz, move around really fast, hit every enemy only once with Electro DMG, Oz is summoned after the burst ends. You will be using this mainly to reset Oz's cooldown. More on this in How Fischl Works. This ability gets extremely powerful with Fischl's 4th constellation.
Passive Talent 1Stellar PredatorWhen Fischl hits Oz with a fully-charged Aimed Shot, Oz brings down Thundering Retribution, dealing AoE Electro DMG equal to 152.7% of the arrow's DMG.This is a nice talent, but you shouldn't be doing aimed shots with Fischl often, so this won't be that useful.
Passive Talent 2Lightning SmiteIf your active character triggers an Electro-related Elemental Reaction when Oz is on the field, the enemy shall be stricken with Thundering Retribution, dealing Electro DMG equal to 80% of Fischl's ATK.This is an insane passive. With Oz on the field, Electro status will have extremely high uptime on enemies, which gives ample chances to proc elemental reactions to trigger this passive.
Passive Talent 3Mein HausgartenWhen dispatched on an expedition in Mondstadt, the time consumed is reduced by 25%.No big deal.


 LevelNameOfficial Description
1Gaze of the DeepEven when Oz is not present in combat, he can still watch over Fischl through the crow's eyes. When Fischl attacks an enemy, Oz fires a joint attack through the crow's eyes, dealing 22% of ATK DMG.

Note: The additional attack is fired from the orb near Fischl's shoulder and is only fired on normal attacks that have locked on to an enemy, regardless if it is blocked by obstacles or missed. The attack has slight homing and may bypass obstacles.

2Devourer of All-SinsWhen Nightrider is used, it deals an additional 200% ATK as DMG, and its AoE is increased by 50%.
3Wings of NightmareIncreases Nightrider's skill level by 3. Max level is 15.
4Her Pilgrimage of BleakWhen Midnight Phantasmagoria is used, deals 222% of ATK as Electro DMG to surrounding enemies. When the skill duration ends, Fischl recovers 20% of her HP.
5Against the Fleeing LightIncreases Midnight Phantasmagoria's skill level by 3. Max level is 15.
6Evernight RavenIncreases the duration of Oz's summoning by 2s. Additionally, Oz attacks with your active character when present, dealing 30% of Fischl's ATK as Electro DMG.

Diving Into Fischl: Maximizing Damage

How does Fischl work?

In case of a support build, we want to summon Oz using Fischl, then immediately switch to our carry DPS. When Oz's time of 10 seconds is up and Fischl's elemental burst is ready, we switch back to Fischl, use her burst which will bring Oz again, and switch back to our carry DPS. Of course you could be switching to other characters to enable your carry DPS to deal even more damage (such as switching to Bennet to use his burst before switching to your carry), or to trigger elemental reactions using your other supports, but this is the normal cycle of a support Fischl. What does this mean? It means that since we'll be using Fischl for her Oz, we want him to have insane damage on the field, which is what we'll base our support build on. Note the importance of using your burst AFTER Oz's time is up after using your E. Oz has a cooldown of 25 seconds and an uptime of 10 seconds. It's very important for Fischl to keep Oz on the field as long as possible. This is the reason we use the burst after 10 seconds of using E. It will bring Oz back on the field for another 10 seconds, which means Oz can be on the field for up to 20 seconds with proper ability management, and if you have Fischl's 6th constellation unlocked, you get an additional 2 seconds for Oz.

In case of a DPS build, usually Fischl will be your main DPS, while the rest of your team supports her. Of course there are many playstyles for teams, so what other characters you have on your team will depend on what playstyle you prefer, but lets leave team playstyles and general team building for another day.

What constellations are worth aiming for?

If you're playing Fischl as a main DPS, her first constellation adds a lot of damage, as Oz will fire a shot for every normal attack Fischl fires in addition to his own attacks. These attacks are counted as normal attacks, so they scale even better with Physical DMG builds.

Her 4th constellation is also insane, as you will deal huge AoE DMG on usage of your burst and will heal 20% of your max HP. As her burst charges up fairly quickly especially with the right team, and she's a ranged character, you could probably survive on Fischl without a healer most of the time. The AoE DMG is really nice for a support build as well.

Her 6th constellation is simply busted, whether you're playing support or DPS. You get additional time for Oz, and more importantly, in addition to Oz's electro attacks, you deal 30% of Fischl's ATK as Electro DMG (scales on her stats) on every hit. If you have this constellation unlocked, Genshin Impact gods are telling you to build an Electro Princess.

Talent upgrades?

For a DPS build Fischl, you want your talent priorities to be: Bolts of Downfall > Nightrider > Midnight Phantasmagoria. Your normal attacks are still faster than Oz's attacks, and you could be running a physical build on Fischl, so your normal attacks are important to level up. You will still need Oz's damage to apply Electro and possibly trigger reactions through other supports like Xiangling's Guoba, and if you have constellations for Fischl, this is even more important. If you're running an Electro build, most of your damage will still be through your Oz and burst, though you still want your normal attacks to deal decent damage, so your talent priority would change to : Nightrider > Bolts of Downfall > Midnight Phantasmagoria.

For a support build Fischl, it should be: Nightrider > Midnight Phantasmagoria > Bolts of Downfall. You won't be using your normal attacks with a support build, which is why Bolts of Downfall is least important here. All of your damage will be through Oz, so you should focus solely on maxing his talent, then transfer to levelling up Midnight Phantasmagoria.

Building Fischl

When it comes to character building, Fischl is special because you can literally use the same build for Fischl, whether you're playing her as a main DPS or a support character, though you get a few more options if you decide to play her as a main DPS.

Weapon Choice

What we want in a Fischl weapon is something that boosts Oz's damage, and in case of a DPS build, Fischl's damage as well. So we should be looking at bows with good Base ATK and sub-stats that are relevant to Fischl. Here we will be giving weapon recommendations for Fischl. Other than the special cases of the Rust bow and The Stringless, the order of strength is the same for both DPS and support roles. The reason for this is that the passive abilities for most bows do not apply to a support style gameplay. For example: Prototype Crescent's passive only happens with Aimed Shots, but if we're running a support build we won't be doing normal or charged attacks often with Fischl, but rather switching to other characters after dropping Oz on the field.

So for a support build, we would mainly consider the main and sub stats of the bow to determine its strength. The exception to this would be the Skyward Harp, because its CRIT DMG boost passive applies to Fischl unconditionally, meaning it also boosts Oz's damage. This is the reason the Skyward Harp is the greatest bow for Fischl, period.

For a DPS build, we do consider the strength of the bow's passive ability when determining its strength. The order of strength just happens to be (almost) the same as if we were looking at weapon choice for a support build.

 NameBase StatsPassive Effects (R1)Reasoning
Skyward Harp

Base ATK: 48

Substat:  CRIT Rate 4.8%

Increases CRIT DMG by 20/25/30/35/40%.

Hits have a 60/70/80/90/100% chance to inflict a small AoE attack, dealing 125% Physical ATK DMG. Can only occur once every 4/3.5/3/2.5/2s.

This is the best bow for Fischl, whether you're running a main DPS or a support build (Unless you have a Rust bow refined to level 5. Read the special case below). CRIT Rate and CRIT DMG are extremely important stats for Fischl towards the endgame, and this bow gives a great amount of both of them. Moreover, since it is a 5-star bow, its ATK stat scales more than 4-star bows, and as a matter of fact, this bow gives the highest Base ATK stat among all bows, even the Amos Bow. At Level 90, it gives 674 ATK, while the Amos Bow gives 608 ATK at the same level.
Amos' Bow

Base ATK: 46

Substat: ATK 10.8%

Increases Normal Attack and Aimed Shot DMG by 12/15/18/21/24%.

Increases DMG from arrows shot by a further 8/10/12/14/16% for every 0.1s that the arrow is in flight, up to 0.5s.

This bow has insane amount of ATK, which Oz's damage scales off. Unlike the Skyward Harp, its passive does not boost Oz's damage. Moreover, though the huge ATK stats are really nice, towards the endgame Elemental Damage, CRIT DMG and CRIT Rate become much more valuable than ATK that becomes less relevant because of stats scaling. As for DPS builds, the passive gives a really nice damage boost, but it's still less valuable than the CRIT Rate and CRIT DMG stats on the Skyward Harp. So, this goes right under the Skyward Harp.
Blackcliff Warbow

Base ATK: 44

Substat: CRIT DMG 8%

After defeating an enemy, ATK is increased by 12/15/18/21/24% for 30s. This effect has a maximum of 3 stacks, and the duration of each stack is independent of the others.This bow's passive applies even when Fischl is not on the field, and it has CRIT DMG for its sub-stat, and has the highest base ATK compared to the ones below it, so it's right below the 5-star bows.
The Viridescent Hunt

Base ATK: 42

Substat: CRIT Rate 6%

Upon hit, Normal and Aimed Shot Attacks have a 50% chance to generate a Cyclone, which will continuously attract surrounding enemies, dealing 40/50/60/70/80% of ATK as DMG to these enemies every 0.5s for 4s. This effect can only occur once every 14/13/12/11/10s.The passive has the effect of a prolonged Sucrose's E, and has a 50% chance of occurence which is great, so if you're willing to shoot a few arrows before switching to your carry DPS, you can trigger this effect then shred through the gathered enemies with your main DPS. For a DPS build, Oz targets single enemies, and your burst is the only option to attack all enemies, but even then it's fairly easy to hit all enemies with the burst by moving around, and you only hit enemies once with your burst anyway, so it's not that useful, but still a nice addition of some damage. The bow also has CRIT Rate for its sub-stat, which is really nice.
Compound Bow

Base ATK: 41

Substat: Physical DMG 15%

Normal Attack and Aimed Shot hits increase ATK by 4/5/6/7/8% and Normal ATK SPD by 1.2/1.5/1.8/2.1/2.4% for 6s. Max 4 stacks. Can only occur once every 0.3s.

Really nice bow especially for a Physical DPS build due to the sub-stat, and you get a lot of attack from its passive too. Craftable, so F2P friendly as well.
Prototype Crescent

Base ATK: 42

Substat: ATK 9%

Aimed Shot hits on weak points increase Movement SPD by 10% and ATK by 36/45/54/63/72% for 10s.Has an ATK sub-stat which is nice, and it's craftable so it's F2P friendly. Pretty good passive too, as a headshot counts as a shot on a weak point. Trigger the passive and swap to your main DPS if you're running Fischl as support. The reason it's coming in last is because better bows provide CRIT as a sub-stat, and all of their passives don't require aiming to be triggered.
Special Cases

Base ATK: 42

Substat: ATK 9%

Increases Normal Attack DMG by 40/50/60/70/80% but decreases Aimed Shot DMG by 10%
The reason for this bow being a special case is because it is the only one among the ones we have listed here that depends on what build you're running to determine its strength compared to other bows. If you're running a DPS build, then this bow goes right below the Amos' Bow. At refinement level 5, it's better than both 5-star bows unless they're refined. This is because of its insane passive ability. Remember, for a DPS build you will be using Fischl's normal attacks along with Oz unlike a support build, so you benefit greatly from normal attack DMG boosts. At refinement level 5 you get 80% Normal Attack DMG boost, which is insane. In addition, this is a 4-star bow, and while its still a gacha bow, it's certainly easier to obtain than 5-star bows, which means it's easier to refine. This bow is even more insane if you're running a Physical DPS build, as most of your damage will be from your normal attacks. The passive of this bow and the difference it makes when you're playing a DPS build is what makes it a special case, as other bows' passives don't make this much of a difference in damage regardless of the build. Note that this bow's passive does NOT apply to Oz.
The Stringless

Base ATK: 42

Substat: Elemental Mastery 36

Increases Elemental Skill and Elemental Burst DMG by 24/30/36/42/48%.This bow's passive applies to Oz's damage, which is a really great boost. It also gives some Elemental Mastery, for those who believe in EM Fischl (which we'll talk about in Artifact Choice notes). If you're running a support build, this bow is really nice. With refinements, it could be right below the 5-star bows just because of its passive.

Artifact Choice

DPS BuildSupport Build
ArtifactsImportant Info/ReasoningArtifactsImportant Info/Reasoning

2-Piece Bloodstained Chivalry

2-Piece Gladiator's Finale


2-Piece Thundering Fury 

2-Piece Gladiator's Finale

It's the "few more options" we were talking about earlier in the guide. If you decide to use Fischl as a main DPS, you have the option of going for a Physical DMG build.

The 2-set bonus of Bloodstained Chivalry gives +25% Physical DMG. We also get additional ATK from the Gladiator's Finale. This will greatly boost both Fischl auto-attack and Oz's damage.

The 4-piece Bloodstained Chivalry set is not worth it for Fischl, because the 4-set bonus only applies to charged attacks, which ideally we won't be doing with Fischl. 4-set Gladiator's Finale bonus also doesn't apply because Fischl is a bow user.

You can also choose to go with 2TF + 2Glad, which will make your Fischl very versatile. You can play both DPS and support with that.

2-Piece Thundering Fury

2-Piece Gladiator's Finale


2-Piece Gambler's


4-Piece Thundersoother

2TF + 2-Gambler is an amazing option as it will greatly enhance your Oz's damage through both of the 2-set bonuses. The 2-set bonus of the Gambler's set does apply to Oz.

You're better off going with 4TS rather than the 2TF + 2GF build for support, as it offers a larger boost to DMG than 2TF + 2 Glad (Though this could vary depending on your sub-stats)

2TF + 2GF gives a great balance by providing both Electro DMG and ATK%, which Oz's damage scales off. And again, if you have this you can use it for both support and DPS, though in this case you MUST use an Electro DMG goblet as you won't be doing any Physical DMG. 

Which sets you choose mostly depends on the substats you have on the pieces, though 2TF + 2-Gamblers is mostly the best option.

2-Piece Bloodstained Chivalry

2-Piece Thundering Fury

We get both the Electro DMG bonus for our Oz and Elemental Burst, and the Physical DMG bonus for our normal attacks.

2-Piece Thundering Fury

2-Piece +18% ATK/ 2-Piece Berserker

At this point we're running out of useful 5-star artifact sets for Fischl, so we come down to 4-star ones and combine them with the +15% Electro DMG bonus from 2-set Thundering Fury. You can use either the Brave Heart or the Resolution of Sojourner 2-piece sets for the +18% ATK, or a 2-piece Berserker set for the CRIT Rate. Which one you use will depend on your current stats and the sub-stats of these sets. For endgame, you want at least 50% CRIT Rate, so if you don't have that, go with the Berserker's set. If you do have that, you can go with whatever has the better sub-stats. Note that Brave Heart, and Sojourner sets are not available as 5-star sets, which will give overall lower stats, but the bonuses compensate for that a bit.

4-Piece ThundersootherWith this set, we can get a lot Electro DMG through the 4-set effect of +35% Electro DMG, which will maximize our Oz and Elemental Burst's damage, though we're sacrificing some of our normal attacks' damage for that, but it's worth it if you're not up against innate Electro enemies.4-Piece Thundering FurySome people might be confused why I placed this last, but it's basically because I don't believe in triggering elemental reactions with Oz. This 4-set gives extra damage on Electro-related reactions, but that only applies if the one who triggered the reaction was the one who has the set equipped, which is Fischl. Read the last note below this table to learn more. This could be your first choice for a support build if you decide to go with an Elemental Mastery build.

Try to always use an Electro DMG Goblet. Physical DMG one if you don't have that. It doesn't have to be from any set. This is so that regardless of the build you're running, Oz and your burst's damage are always boosted. This becomes more important when you unlock constellations. If you have C1 unlocked, it's fine to go with a Physical DMG Goblet if you're running a Physical build to boost your Oz's normal attacks from the constellation, but remember that most of Oz's damage comes from his Electro attacks. Your burst damage is worth boosting as you'll be using it often, especially if you have C4 unlocked. In addition, Elemental DMG is more consistent when it comes to climbing the Spiral Abyss due to elemental reactions. Though I say this, with a DPS build you still have the option to go with a Physical DMG goblet if you want, maybe to achieve a balance between your Oz's damage and your normal attack damage if you're running 2TF + 2Glad (Note that an Electro DMG goblet is still recommended here for higher damage), or if you feel like completely abandoning Oz for whatever reason and going with a full Physical build of 2BS + 2Glad. Test and see what works for you if you have that luxury.

Things that add "DMG" will offer bigger boosts to overall damage than things that boost ATK, which is why 2TF + 2BS is still a valid option for a DPS build. A lot of math is involved in this scaling, but we can just leave it at that and say that it's just how the game works.

Do not prioritize set bonuses over good main and sub-stats. For example, if you have a maxed 2-piece Gladiator's Finale set with say, DEF and HP main stats, and 2 random artifacts that are both maxed with ATK as their main stat, you will get much more ATK through using the random artifacts rather than going for the Gladiator's Finale set bonus. Keep this in mind when choosing which 2-piece set to pair with 2-piece Thundering Fury or 2-piece Bloodstained Chivalry. HP%, DEF%, Elemental Mastery*, and Energy Recharge are all stats not worth going for as main stats.

*IMPORTANT: Although I believe it's not worth building Elemental Mastery on a DPS Fischl, it could be worth pumping some into a support build, but if you want that, do it through your artifact sub-stats. Your artifact main-stats are more valuable than to stick EM on them. In addition, note that if you decide to do this, you will need a team that can keep up element status on enemies ALL THE TIME, otherwise it's not worth it. This is mainly because you can't really control when Oz fires his shots, and as such don't have much control over who is triggering the elemental reaction if you don't keep your main element's status up on enemies all the time. It's also to make building EM on Fischl worth it, because to achieve damage from a support build running EM that would compare to what you can get through Electro DMG, CRIT and ATK builds, you will need every elemental reaction you can trigger. If you can't trigger them all the time using Fischl and Oz, it's a big damage loss and simply not worth it. I might add this some time in the future, but for now I will refrain from talking about team comps that can achieve this as I personally am not a believer in Elemental Mastery Fischl, although some other people are. You are under no obligation to follow this, or anything in this guide for that matter as rules. If you test things and feel you're getting bigger damage, you can just ignore everything in this guide and go on your own road, or whoever else's you're following. If you feel like you know how to control your reactions and get Oz to always be the one to proc reactions, feel free to build some EM on a DPS Fischl but again, try to not cut on Electro DMG, CRIT and ATK for that. And just to clarify, what I said does NOT mean you shouldn't be triggering elemental reactions; in fact, you SHOULD. Fischl's passive talent, Lightning Smite, will deal extra damage whenever you trigger an Electro-related elemental reaction while Oz is on the field. Note that this is Electro DMG, and the damage is 80% of Fischl's ATK, so the damage from this will scale off these stats. If you decide to build a lot of EM on Fischl, you won't be making optimal use of this talent, unlike if you build for Electro DMG and ATK. If you're running a support build, you can use The Stringless bow on Fischl, which will boost both her Oz's damage, and, if it somehow happens, Oz's reaction triggering damage through its Elemental Mastery substat.

Team Comps

I'm not going to give you full teams to use here, but just general concepts and some examples of characters. You might not have some of the characters, or you don't like playing with them. But I'll tell you this one thing: There's almost never no space for Fischl on a team, and no one way of playing Fischl.

If you're playing her as support, you might want to check your math if you know you're going up against Electro enemies, but other than that, she can fit into literally any comp. Oz can stay on the field for a long time and deal insane damage, while you use your other characters to proc reactions. Pairing her with a main DPS Electro character such as Keqing or Razor will give Electro elemental resonance, which will provide energy for both characters when an Electro-related elemental reaction is triggered, meaning you can greatly increase your bursts' uptime. In addition, remember that one of her passive talents deals additional Electro DMG as a percentage of Fischl's ATK when you trigger elemental reactions while Oz on the field, so you definitely want to use characters that can proc reactions often. You can either use a non-Electo main DPS with high elemental spread on the field for this, such as Klee or Childe (Note that Childe has great AoE control and very fast attacks, so Oz could be the one triggering the reactions in this case), or put in another support for it. If you have Venti, he will pair really nicely with Fischl and another character (Gather enemies with Venti, drop Oz on the field for Electro, proc the reaction with another character for huge damage from Fischl's passive talent), especially if you have Viridescent Venerer on him. You can also use Sucrose or Jean with that set to swirl Electro and apply reduced Electro RES debuff on enemies.

As a main DPS, again, another Electro character on the team with her would be optimal for elemental resonance especially if you're running an Electro build. Other than that, you're free to use whatever characters you want that can help Fischl keep elemental reactions up. You could go for support characters like Xiangling to trigger Overload, or Xingqiu for his amazing burst that would pump out a lot of DPS with your normal attacks and proc Electro-Charged (you get some heals off him too :D). Either way, you'll make optimal usage of your elemental resonance through constantly triggering elemental reactions, giving you lots of energy plus triggering Fischl's passive talent. Beidou is a great option for resonance due to her burst that will deal Electro DMG, especially if you have her 6th constellation which will reduce Electro RES of enemies. As a ranged character, it shouldn't be too hard to dodge attacks, so Fischl wouldn't REALLY need a healer in her team. More so if you have her 4th constellation unlocked, which will heal her with every elemental burst. If you find yourself in need of a healer, you can use Barbara with the 3-star ATK buffing book, or even better, Bennet. If you're running Physical build on Fischl, try to get a Cryo character with her to trigger Superconduct, which will reduce Physical RES of enemies. Qiqi is a Cryo character that can also heal, so that's 2-in-1 if you have her. Chongyun is also recommended as his E won't transform your attacks into Cryo (His effect doesn't apply to bows). He also has a CD reduction on constellation 2, which will help your Oz. You also can try to aim for a double-pyro on your team for the 25% ATK buff (You can use Bennet and Xiangling for this. Bennet will heal you and boost your ATK even more with his burst, and Xiangling for Overload procs).
