Dorothy

A strong Burst 1 against bosses with parts, Interception, and Union Raid. Holy Fire1 cuts Burst cooldown, and Paradise LostB's Brand detonates accumulated damage.
She is a liability in wave stages and high-CP-deficit content, where her instant AoE clearing is slow.

A Burst 1 whose last bullet triggers Holy Fire1 to reduce allied Burst Cooldown, and who gains a Damage to Parts buff during Manifestation.

Using Paradise LostB grants Pierce and Baptism2 cooldown reduction while in Manifestation, and applies Brand to a designated enemy. When the Brand ends, the damage accumulated during it is dealt to all enemies as distributed damage. The accumulation cap is based on Dorothy's ATK.

Baptism2 is distributed damage, so with many mobs the damage per enemy drops. Brand damage is not affected by Full Burst multipliers or enemy Damage Taken debuffs; only ATK applies.

Land the last bullet to keep Holy Fire1's cooldown reduction going.
Paradise LostB applies Brand to the boss body, and you stack parts/body damage until the mark ends.
Auto is fine by default, but in boss fights set the Brand target and last-bullet timing by hand.

Paired with Pierce/single-target boss DPS like Alice and Maxwell. The last-bullet condition does not work with lineups that greatly raise ammo, like Noir and Blanc.

For the last-bullet Holy Fire1, prioritize the Resilience Cube for reload. Use the Assault Cube for Hit Rate and the Bastion Cube for fire support. Skip ammo Harmony Cubes since they make the last-bullet trigger harder.

For both Brand and her own damage, take ATK, crit, and Elemental Advantage damage. Skip ammo lines since they conflict with the Holy Fire1 condition. Hit Rate helps when hitting parts and cores.

Holy Fire1's cooldown reduction and parts buff are the core, so raise S1 first. Baptism2 is supplementary distributed damage, so stop at 4. For Paradise LostB's Brand cap, aim the Burst at 8 or higher, with 10 as the endgame target.

Used in part bosses, Interception, Union Raid, and Tribe Tower for Burst 1 CDR and Brand damage. In wave Campaign stages with a large CP deficit, instant AoE is needed, so she is often worse than Liter or burst-damage lineups.

Holy Fire1 reduces allied Burst Cooldown.
Her Damage to Parts buff during Manifestation greatly boosts firepower against part bosses.
Paradise LostB's Brand can detonate accumulated boss damage all at once.

Brand and distributed damage make her slow at wave clearing.
With allies that greatly raise ammo, it is hard to meet the last-bullet condition.
As an Assault Rifle Burst 1 she generates little Burst Gauge, so she is not an Arena main.
