As Arknights' first "Alter" Operator, Lava the Purgatory isn't merely an enhanced version of her base form—she emerges as a formidable 5-star Splash Caster offering both team utility and unexpected tactical versatility. Capable of delivering devastating AoE damage while simultaneously enhancing other casters' performance, she proves valuable across multiple team configurations.
Unlike most damage-focused Operators in this tactical RPG, Lava the Purgatory provides support while maintaining impressive area-of-effect Arts damage. With two potent skills and a unique SP acceleration talent benefiting all caster teammates, she remains relevant beyond specialized scenarios. Let's examine her capabilities and optimal setups.
Operator Overview
This 5-star Splash Caster unleashes AoE Arts damage across wide areas, like all operators in her class. Her attacks excel against enemies with low-medium RES, but she distinguishes herself through team synergy capabilities and her second skill's transformative gameplay impact.
Initially available as a welfare Operator during the Who is Real event, she's permanently obtainable via Record Restoration. Compared to her original form, this iteration boasts superior stats, Elite 2 promotions, and more nuanced gameplay. While sharing Trust status, she features completely separate upgrade paths, potential unlocks, and skills.
Talents: Spell Formation and SP Support
Lava the Purgatory's combat effectiveness stems primarily from her signature talent, Spell Formation. This grants immediate SP upon deployment and shares SP bonuses with all fielded casters—scaling with promotion level. At Elite 2, she receives 30 initial SP and provides +4 SP to all deployed casters each time she enters battle.

She synergizes exceptionally well with defensive formations. Her Ring of Hellfire skill creates burning zones that protect defenders, making her ideal for containment strategies and chokepoint battles.
Recommended synergy partners include:
- Eyjafjalla or Ceobe: Amplifies AoE damage while benefiting from SP acceleration
- Saria or Nearl: Tank-healers who create stable zones for her burning field
- Other Splash Casters: Operators like Goldenglow and Skyfire gain significant value from faster skill cycling
Lava the Purgatory represents a meticulously designed Alter Operator combining AoE pressure, tactical support, and team enhancement. New players appreciate her straightforward splash damage, while veterans utilize her SP-boosting mechanics and area control capabilities. Whether orchestrating caster-centric compositions or reinforcing defensive lines with fire zones, she consistently delivers strategic value.
For optimal performance, consider playing Arknights on PC via BlueStacks. The expanded battlefield view, precise controls, and enhanced visual clarity prove particularly valuable when positioning skills like Ring of Hellfire with tactical precision.
