Yvonne is a 6★ Caster in Arknights Endfield and a core Cryo damage dealer built around one idea: convert Infliction stacks into Solidification, then cash that state out for Ultimate Energy and crit-loaded burst. This article lists her stats, skills, promotions, and progression first, then explains how her rotation actually plays out once you’re fighting real enemies instead of a training dummy.
If you are comparing Yvonne to other operators or trying to understand where she stands in the broader meta, this article is written to slot directly into our Arknights Endfield Tier List, where all characters are evaluated under the same conditions and assumptions.

Analysis & Verdict
Yvonne’s kit is easy to describe if you keep it concrete: she wants Infliction stacks on the target, then she turns those stacks into Solidification, and Solidification is what lets her cash out damage and Ultimate Energy. That’s the loop. If the target has no stacks, her Battle Skill is just a bomb. If the target has stacks, Brr-Brr-Bomb becomes a conversion tool — consume everything, lock the target in Solidification, and get paid in scaling damage plus Ultimate Energy.
Flashfreezer υ37 exists to extend that lock and control the space. The trigger is strict (Final Strike on a Solidified enemy), but the reward is practical: Frost-e-Bytee pulls nearby enemies inward, then re-applies Solidification in an area when it expires. In a real fight, this is what turns “single target setup” into “the whole pack is now standing where you want them.” That’s why Gilberta pairing shows up so often: grouping makes her slow delivery stop being a problem.
Cryoblasting Pistolier is a crit ramp into a big finishing hit. You stack Critical Rate through enhanced basic attack sequences, then you get the Critical DMG payoff once stacks are maxed. The important detail is the Solidification clause: if the enemy is Solidified, she gets an extra Cryo hit and consumes the state. So in practice you want Solidification to be present right before the Ultimate’s ending window, not ten seconds earlier when the fight is still moving.
The friction is also obvious once you play her. Both her Battle Skill and Combo Skill only pay Ultimate Energy once per cast, even if multiple enemies get hit. So you don’t “cheat” the meter by throwing bombs into crowds. You win by making sure the cast that matters consumes the stacks that matter. That’s why her teams care about dedicated stacking (Xaihi + Estella, or a Cryo stacker like Last Rite/Snowshine depending on the fight): you’re feeding Yvonne the exact resource she’s designed to convert.
Verdict: Yvonne is a Cryo carry whose damage and Ultimate cycling depend on clean Infliction stacking and correct timing on Solidification. When her setup is supported, she delivers strong single-target burst with enough control/AoE tools to function in waves. When setup is sloppy, her kit still works — it just stops looking “limited DPS” and starts looking like a regular caster throwing bombs on cooldown.

Yvonne’s power curve is tied to Promotions, Potentials, and the supporting roster that feeds her consistent stacks and clean burst windows. Building a full Cryo setup takes time — especially if you’re upgrading multiple operators in parallel.
