⚡️ Fischl was one of the very first characters that carried me through the early days of my Genshin journey. I've used her in my team even when I hadn't understood about character building whatsoever. She was then benched for quite some time because tbh I didn't really like bow characters. But after dendro got introduced to the game, I started taking care of Fischl more than ever.
⚡️ Disclaimer: This build is not perfect and by no means should be treated as a rigid rule. I just share what I have tested in game and what I know works for me. So always do your own research and take my guide with that note in mind!
Artifact Set
⚡️ Fischl has had many versions of artifact sets. From Thundering Fury to Gilded, to now Golden Troupe era. Fischl is such a strong unit especially at C6. And her build is slightly different between C0 and C6 as she gets more atk boost when her constellation is all unlocked. At C6, she can use EM sands which can work wonder if you put her in dendro team.
⚡️ Here are some of the artifact sets I know will work on her:
2 pc Thundering Fury + 2 pc atk% (Gladiator/Shimenawa/Echoes/Vermillion)
2 pc atk% + 2 pc atk%
4 pc Gilded Dreams
4 pc Golden Troupe
⚡️ Post dendro, Fischl easily becomes my sub-dps in Alhaitham's spread team, helping the team by giving consistent electro to help trigger quicken reaction with Alhaitham as well as damaging the enemy.
⚡️ I would recommend farming Golden Troupe only if you still haven't had any good 4 set for her. Originally I wasn't gonna change her build cuz she already had 4 Gilded on her but since I had to farm for Neuvillette's artifact, I ended up with some decent Golden Troupe pieces. The damage increase is pretty nice, I got an increase of 5.000 skill damage after changing from Gilded to Golden Troupe.
Ratio to follow: >60% crit rate, 120% cdmg, 1.500 atk, 100 EM, >120% ER
⚡️ Her burst is quite important as it resets Oz, her raven. Think of her like Kokomi. The burst itself doesn't do a ton of damage but it helps resetting Oz's duration on field so when her skill is on cooldown (cuz it does have long cooldown), you can just burst instead and then immediately switch characters to summon Oz right then and there.
Team Composition
Alhaitham spread team
⚡️ She can work in many team comps that need electro sub-dps. You can put her in spread team, or even taser team with a hydro applier. Though she's not recommended for hyperbloom team despite being an electro off field because just like Yae's totem, Oz targets enemies, not dendro cores. So there's a higher chance that she won't be able to trigger hyperbloom at all.
Weapon Choice
⚡️ She can work with many types of weapon; atk%, EM, ER, or even crit weapons. I put mine with Stringless because of its passive to enhance elemental skill damage. Sadly even after playing 2 years and reaching AR60, my Stringless is still at refinement 1. At refinement 5, that weapon can provide 46% skill damage bonus.
Talent Priority
⚡️ Fischl is a quick swap unit, meaning she's gonna be on field for a mere few seconds only to do setup before she switches back to another unit. Her main source of damage comes from her skill, which is why it should be your first priority. Followed by her burst, though in my opinion you can just leave it at 6 at least.
So that’s pretty much my Fischl build. Feel free to ask me questions if you have any through my ask box or just leave comment on this post and I’ll respond right away!
