A Complete guide for the Prinzessin der Verur- I mean Fischl
Rejoice insignificant lifeforms, I shall bestow you with knowledge beyond your mere singular grasp through only bashful enlightenment of thy spiritual guidance shall you finally gaze at the light in the infinitesimal of the night sky and find purpose to your albeit trivial existence.
In Oz's words: Ahem, we will be covering a guide for both advanced & intermediary Fischl.
Fischl is an amazing character aside from her very unique way of communicating with her allies.
She's a good asset in your team as either support or main dps.
Talent & Passive of the Princezzin
Before you begin to ascertain how you should be gearing her, it's very important to look at her talents and constellations.
Talent
Normal Atk : 44% , 46%, 58%, 58%, 72% (4.5second to complete with fast pressing)
Aimed Shot - Low charge : 44%
Aimed Shot - Full charge : 124% (4 second to fully charge)
Nightrider(E.Skill): Oz will remain on the field for 10s/25cd.
Pressing again allows you to reallocate Oz -doesn't affect duration.
Oz do 89% of Fishl's Atk as Electro Dmg
Midnight Phantasmagoria(E.Burst) : Fischl will transform into Oz allowing her to move faster.
Each enemy can be strike for 208% Electro Dmg in its AoE.
At the end of this Skill, Oz will be reposition at the that location
Also resetting Oz duration.
Stellar Predator: This talent is unlocked at Ascension 4.
This allows you to shoot a fully charged arrow at Oz for 157% Aoe Electro Dmg.
Lightning Smite: This talent is unlocked at Ascension 6
This allows you to do 80% of Fischl's Atk when triggering an Electro-Related reaction while Oz is on the field
Mein Hausgarten: She takes 25% less duration to complete an expedition.
With Patch 1.1, She can be now sent on expedition while in Party as well.
Constellation
1 Gaze of the Deep - Gains 22% atk dmg from Oz no matter what.
2 Devourer of Sin - do an additional 200% Atk dmg upon using Nightrider
Oz Aoe is also increased by 50%
3 Wings of Nightmare- Nightrider+3
4 Her Pilgrimage of Bleak - Does 222% atk AoE upon using Midnight Phatasmagoria.
Fischl recover 20% hp after.
5 Against the Fleeing Light - Midnight Phatasmagoria+3
6 Evernight Raven - Oz attack do an additional 30% of Fischl's ATk as Electro Dmg.
This dmg also works when switching active character.
Fischl as a Main dps-Physical dmg oriented
This is the easiest way to build and play Fischl as main dps.
Recommended stat priority : crit rate , crit dmg %, attack power %
physical dmg %.
Recommended artefact set bonus: Berserker set 1 (12% crit rate)
Gladiator Final set 1 (18% atk)
Others:
Martial artist set 1 (15% dmg normal charged atk)
Bloodstained Chilvary (25% Physical dmg)
Recommended Talent focus : Normal Attack
Main dps Fischl should focus on making sure to attain at least 45% crit rate to be crit dmg efficient,
you want to also maximize right after crit dmg which affect both your dmg and that of Oz. Martial artist and Bloodstain chilvary will singularly help you in gaining more dmg from your passive, at the very least if you're focusing on gaining dmg from Gaze of Deep or Nightrider.
Recommended playstyle style - Single Target
She should focus on using normal attacks which will do a total of 278% Atk dmg over 4.5second than charged attack on single target dps to maximize her dmg since charged attack only do 124% over 4.5second.
Recommended playstyle - Multi Targets
Fischl 'may' seem weak against a horde of enemies, but if you focus on doing dmg with Lightning Smite
by shooting at Oz. You'll do amazing AoE dmg as it has no cooldown. You'll need to have Oz right at the center of your enemies or you'll have to reposition it. It's better if you have a character which has a 'dummy' skill such as Amber or Mona. Mona being the best pick here since you'll gain a lot of Elemental reaction dmg. However you'll need to be careful since Oz only stay on the field for 10s/25 cd which means that Oz uptime is 40%. People who focus on Physical dmg% and Normal dmg% will also lose a lot of dps vs group of enemies as Lightning Smite scale only with Attack power while Phys dmg only gives you only 2-4% dmg vs single target dps. So make good choice on how you'll play her.
Elemental reaction recommended: Superconduct (+25% Physical dmg)
You might consider a team with Fischl as main dps with Mona as support, and a cryo unit for Frozen and Superconduct which gives you enough time to time your Lightning Smite with superconduct on your frozen enemies.
Fischl as a Main dps- Elemental dmg oriented (End game)
As of now, since we don't have any good set x4 which focus on purely improving attack power
thunderfury will remain the best set for Fischl end game as main dps.
Main stat priority : crit rate% , crit dmg %, attack power %, electro dmg %, elemental mastery
and at least 20% Elemental recharge.
Recommended Talent focus : Normal Attack (priority) , Nightrider (secondary)
Recommended artefact Bonus - Thunderfury set 1 & 2
Other : Thundersoothing set 1 & 2
Thunderfury set, will give you 15% electro dmg , and reduce the cd on your E.Skill by 1 for every since Oz remains on the field for 10second and attack the target upon being summoned and every 1second for a total of 10 attacks + 1 summon attack if they are in his Aoe. If you're able to maximize
on elemental reaction for E.g with a Mona's E.Skill, you might gain as much as -11s of cd which makes
Oz uptime 10sec/14cd or an uptime of 74% enough for Stellar Predator and Lightning Smite.
Note that you'll also be gaining a lot of Energies with reactions and even though your main dps doesn't
come from your Elemental Burst, you want to make best use of it to refresh your E.Skill which is why at least 120% Energy recharge is important. Any E.Recharge above will be wasteful since your Oz uptime will be almost 99%. You're not recommended to go with High Voltage with Thunderfury on Fischl.
You can also use the Thundersoothing set which gives you a whooping +35% electro dmg on Electro debuff enemies. However your oz duration will be 40% which will make it harder to keep electro debuff for the set bonus on your target and for your passive which will make you a burst dps.
I'll highly recommend you if you're going with Thundersoothing set to make good use of your Sync Bonus for High Voltage and around 140% Energy recharge to help you maintain your Oz if you want constant dps. Lisa is the best support for Fischl with Thundersoothing set.
I still think the Thunderfury set is better for Fischl as you can focus on other sync bonus or elemental reactions which makes your party more versatile, you're also able to use Fischl as a support with this set.
Recommended Playstyle
You're recommended at ALL time to use only Charged attack if you have a big 30% or higher Electro dmg. Note that Goblet artefact can have electro dmg on them to help you reach this figure.
Fischl can deal with any type of enemies except Electro Slime or enemies with electro shield.
Similarly Fischl won't be gaining much dmg against Cryo Slime or enemies with cryo shield.
So you're recommended at any rate to swap to your support to deal with those before your Fischl can handle back her role as main dps.
Recommended Elemental reaction: Electro-Charged (40% dmg with set)
Support recommended: Mona
Fischl as Support
Fischl is easily one of the best support in the game, not only does her Oz stay on the field for 10second but it can be reposition. Many of her Constellations also leads her toward being either a great elemental dps or a support. As a support, Fischl will need around 170% Elemental Recharge and you'll want to focus on attack power that will directly affect Oz dmg
Recommended set: Thunderfury set
Recommended weapon : E.Recharge(priority) or Elemental Mastery(secondary).
I often see people say the Stringless is the best support Bow for Fischl. But I'll go against this thought.
It's at best at being the easiest way to do great as a support.
Assuming you're able to keep a constant in your stats atk power, electro dmg% with any bow and by looking at only the sub effect of the bow we can say that the Sacrificial Bow is maybe the best bow for Fischl as a support since the effect to reset fischl E.Skill has a 60% chance to occur upon doing dmg to enemies with E.Skill which last for 10second. This defies thus the need to have a 70% Recharge as stat on her.
This means you can focus on crit to compete with The Stringless 24% dmg vs 50% crit dmg.
I also did mention that Elemental mastery isn't a priority stat as support.
Recommended Talent : Nightrider
I know it's a long guide. I've compiled all I've gained as knowledge using Fischl from reading and analyzing. Many of you will have a Fischl after the event of patch 1.1 and I hope this detailed guide will help you make best use of your Fischl.
