D

A Wind Code Burst 3 whose core is ChastisementB's Damage to Parts buff. She is used as a sub DPS in fights with parts, such as Interception, part bosses, and Union Raid.
She is rarely a core pick in the current meta, and her own firepower is low without elemental advantage.

Every time Full Burst starts, Vigorous Waves1 grants her an Elemental Advantage Attack Damage increase and recovery proportional to Attack Damage. When a target appears, Surprise Attack2 fills a large amount of Burst Gauge for all allies (1 per battle), grants immunity to Stun, and gives her an elemental damage increase. Her Burst, ChastisementB, damages all enemies and grants all allied Attackers Increased Damage to Parts for 15 seconds.

Using ChastisementB while immunity to Stun is active extends Full Burst duration. Targets only apply to single large enemies such as Campaign, Interception, and Co-op bosses, not to Arena. Against bosses without parts, the ChastisementB buff loses much of its value.

In boss fights where you need to break parts, use ChastisementB to open the Damage to Parts buff for allied Attackers.
Rotate your Burst after the 1-time Surprise Attack2 trigger right after a target appears.
Auto is fine by default, but for DPS with long Burst timing like Maxwell, sync manually to land their Burst inside the 15-second buff.

She is sometimes slotted into Interception in place of Privaty. Her buff window does not line up with lineups that greatly raise ammo or with long-Charge DPS, so they are hard to pair.

For her parts damage support role, prioritize the Destruction Cube. Use the Assault Cube for Submachine Gun Hit Rate and the Resilience Cube to sustain fire.

When you also want her own damage, set Elemental Advantage damage and ATK lines. Use leftover lines on Hit Rate and crit to support Submachine Gun fire.

ChastisementB's parts buff is the core, so raise the Burst to 7-8 first. Vigorous Waves1 triggers every Full Burst, so S1 comes next. Raising S2 to 4 or higher lengthens the Full Burst extension and can actually hurt, so stop at 1-4.

Used for her ChastisementB buff in Interception, Union Raid, and bosses with parts. In Campaign she is occasionally slotted against stunning bosses such as Sentry. She is not used in Arena because targets and Surprise Attack2 do not work there.

ChastisementB greatly boosts Damage to Parts for allied Attackers for 15 seconds.
When a target appears, Surprise Attack2 fills the Burst Gauge in one go and grants immunity to Stun.
If the enemy is weak to Wind, the elemental damage from Vigorous Waves1/Surprise Attack2 boosts her own damage too.

Her buff is almost worthless against bosses without parts and on wave-focused stages.
Without elemental advantage, her own Submachine Gun firepower is low.
Overinvesting in S2 can lengthen Full Burst and reduce damage efficiency.

Immunity to Stun does not block the stun damage itself. Attacks such as Modernia's laser are not fully countered by it.
