Yvonne pairs huge Ultimate burst with consistent Solidification that freezes non-boss targets and opens Cryo or Nature infliction routes for teammates. Gilberta, Xaihi, Tangtang, and Estella all show up around her kit on serious Monument clears — this is a real Cryo burst lane, not a side project. Pull her if you want a Cryo carry that also buys survivability through Solidify; hold if your Cryo slot is already Last Rite and you would rather fund that lane’s supports.
Yvonne is a 6★ Cryo Flex DPS (Handcannon). Yvonne is an Operator that acts as hardcore Cryo DPS with a specialization in Solidification.

Picking Yvonne’s skill priority was a bit of a difficult task at first, but after looking at the numbers there was a clear.
Level after higher priorities — supports the ultimate role in the rotation.
Level after higher priorities — supports the battle skill role in the rotation.
Level after higher priorities — supports the combo skill role in the rotation.
Yvonne is an Operator that acts as hardcore Cryo DPS with a specialization in Solidification.
Her optimal rotations involve chaining her Battle Skill on enemies with either Cryo or Nature infliction already applied to inflict solidification, performing a final strike on a solidified enemy, triggering combo skill, and then activating Ultimate to dish out maximum damage.
Use these notes as the operator priority order inside the comps above.

Intellect Boost [L] · Critical Rate Boost [L]
Cryo DMG Dealt +16/28.8/44.8%. After the wielder scores a critical hit with a battle skill or combo skill, the wielder gains Cryo DMG Dealt +14/25.2/39.2% for 30.00s. Max stacks for effects of the same name: 3.00. Duration of each stack is counted separately. Effect only triggers once every 0.1s.
Why it works —Artzy Tyrannical grants a flat bonus Cryo damage and also gives an additional Cryo damage bonus after scoring a critical hit with a battle skill. This is also Yvonne's Signature weapon, and its apparent by its effects.

Intellect Boost [L] · Cryo DMG Boost [L]
Critical Rate +3.5/6.3/9.8%. When Solidification or Corrosion is applied to enemies, the wielder gains Cryo DMG Dealt and Nature DMG Dealt +3.5/6.3/9.8%, and Critical Rate +2/3.6/5.6% for 15.00s. If this effect is triggered by the wielder, double the increase gained. Effects of the same name cannot stack.
Why it works —Yvonne's Protocol Pass weapon. After she hits an enemy with either Cryo or Nature infliction with her Brr-Brr-Bomb β Battle Skill to solidify them, she'll trigger the improved version of this weapon's effect, granting her improved Cryo DMG and Critical Rate.

Main Attribute Boost [L] · Critical Rate Boost [L]
Arts DMG Dealt +12/21.6/33.6%. When the wielder casts a battle skill, the wielder gains Arts DMG Dealt +8/14.4/22.4% for 15.00s. When the wielder's battle skill applies an Arts Reaction, the wielder gains Arts DMG Dealt +16/28.8/44.8% for 15.00s. The two effects apply separately and do not stack with themselves.
Why it works —Wedge grants a flat arts damage boost with additional arts damage boosts for casting a battle skill and applying an arts reaction with a battle skill.

Agility Boost [M] · Arts Boost [M]
Critical Rate +3/5.4/8.4%. When the wielder applies an Arts Reaction, the wielder gains ATK +7.5/13.5/21% for 20.00s. Max stacks for effects of the same name: 2.00. Duration of each stack is counted separately. Effect only triggers once every 0.1s.
Why it works —For a 5 Star option, Opus: The Living works decently. This weapon pumps up Yvonne's arts damage and grants an addition boost when she applies an Arts Reaction.

MI Security is Yvonne's BiS. Crit Rate from the 3pc plus stacking ATK on crits matches a Basic Attack–heavy Intellect kit that crits often enough to keep the buff rolling.

Yvonne Cryo/Arts: Xaihi buffers, Tangtang stops the field, Arcane adds setup — Yvonne lives in Basic Attack and Ult loops inside those windows.

Yvonne is the Cryo Arts carry — Basic Attack and Ult loops inside Xaihi/Tangtang windows.
Arcane either dumps Nature/Cryo damage in INT form or groups and applies Susceptibility in WILL form. Beside Yvonne, she is the setup/burst flex that creates a clean window to spend.
Tangtang's Ultimate is a full-screen time-stop. Cast it so Yvonne (and the rest of the squad) can dump skills safely without the wave moving out of position.
Xaihi is the Cryo/Arts buffer seat — Amp from Battle Skill and team Cryo/Nature amp from Ultimate so Yvonne's damage windows are actually buffed.
BASIC ATTACK: An attack with up to 5 sequences that deals Cryo DMG. As the controlled operator, Final Strike also deals 17 Stagger. DIVE ATTACK: Basic attack performed in mid-air becomes a dive attack that deals Cryo DMG to nearby enemies. FINISHER: Basic attack performed near a Staggered enemy becomes a finisher that deals massive Cryo DMG and recovers some SP.
SKILL DESCRIPTION: Throws a freezing bomb. The bomb explodes when it hits the enemy to deal Cryo DMG. If hitting an enemy with Cryo Infliction or Nature Infliction, then consume all Arts Infliction stacks, forcibly apply Solidification, and deal Cryo DMG to the target based on the number of stacks consumed. After the battle skill successfully applies Solidification, Yvonne gains additional Ultimate Energy based on the number of stacks consumed. This Ultimate Energy Gain effect can only trigger 1 time, even if the skill hits multiple enemies.
COMBO TRIGGER: When the controlled operator performs a Final Strike on an enemy with Solidification. SKILL DESCRIPTION: Immediately deploys Frost-e-Bytee next to the enemy. While active, Frost-e-Bytee constantly releases energy to attack nearby enemies, deals Cryo DMG to them, and pulls them towards itself. After Frost-e-Bytee expires, it explodes to forcibly apply Solidification and deal Cryo DMG to nearby enemies. After the combo skill successfully hits the enemy, Yvonne gains additional Ultimate Energy. This Ultimate Energy Gain effect can only trigger 1 time, even if the skill hits multiple enemies.
SKILL DESCRIPTION: Immediately deploys the support bot Tink-a-Bella and makes Yvonne the controlled operator. Temporarily enhances Yvonne's basic attack (BATK). Each enhanced BATK sequence performed grants a stack of Critical Rate buff. After reaching max stacks, Yvonne also gains a Critical DMG buff. When the skill is about to end, Yvonne's last enhanced BATK becomes an enhanced Final Strike that deals massive Cryo DMG. If the enemy is Solidified, Yvonne performs an additional attack that deals Cryo DMG and then consumes the enemy's Solidification.
