Fischl
Who is Fischl?
Fischl is a 4★ Electro Bow off-field sub-DPS and one of the best 4★s in Genshin Impact. Her Raven Oz provides consistent, long-duration off-field Electro application that powers Electro-Charged, Aggravate, Overload, Hyperbloom, and National-variant teams. She is a permanent standard banner unit free to any account and fully functional at C0 — with C6 extending Oz duration to near 100% uptime. Source: https://keqingmains.com/q/fischl-quickguide/
Kit Summary
Summons Oz, who fires off-field Electro bolts for 10s — her core off-field contribution. Oz snapshots buffs on summon.
Fischl transforms into Oz, dealing AoE Electro, then re-summons Oz for another 10s.
When the on-field character triggers an Electro reaction while Oz is present, an additional Electro hit equal to 80% of Fischl's ATK fires — her primary off-field reaction damage source.

F2P Verdict
Fischl is a permanent standard banner 4★ and effectively "free" — every account has or will have her. C0 is already excellent for any Electro reaction team. Use The Stringless for Aggravate or Prototype Crescent/Fading Twilight as F2P bow options. 4pc Golden Troupe is her best artifact set. Off-field build: ~120–140% ER to Burst every rotation; or ~100% ER if only Bursting every other rotation. C6 is the single most impactful upgrade — extending Oz duration so that her A4 passive proc fires far more often. Source: https://keqingmains.com/q/fischl-quickguide/
