Arknights Guide: Alter Caster Build for Lava's Purgatory

As Arknights' inaugural "Alter" Operator, Lava the Purgatory transcends being a simple upgrade – she emerges as a formidable 5-star Splash Caster offering both team utility and versatile deployment options. Whether unleashing devastating area Arts damage or empowering your Caster units, she consistently proves valuable across various squad compositions.

Operator Overview

Lava the Purgatory delivers wide-range AoE Arts damage as a 5-star Splash Caster. While sharing the standard Splash Caster trait of multi-tile attacks effective against low-to-mid RES enemies, she distinguishes herself through her team-focused talent and transformative second skill.

Originally introduced as a welfare Operator during the Who is Real event, she's permanently obtainable via Record Restoration. This version boasts superior stats, Elite 2 potential, and more nuanced gameplay compared to her original incarnation. While sharing Trust with base Lava, these forms feature entirely separate progression systems.

Talents: Spell Formation and SP Support

Lava's signature talent, Spell Formation, defines her combat role. This ability grants immediate SP upon deployment while also sharing SP with all fielded Casters. At Elite 2, she obtains 30 initial SP and provides +4 SP to fellow Casters with each deployment.

Her Ring of Hellfire skill creates excellent synergy with defensive formations, burning adjacent enemies to protect frontline defenders – making her ideal for lane control strategies.

Strategic partnerships include:

• Eyjafjalla or Ceobe: Combines AoE damage with SP boost benefits
• Saria or Nearl: Tank-healers who enable Lava's burning zone tactics
• Other Splash Casters: Operators like Goldenglow benefit from accelerated skill cycling

Lava the Purgatory represents a masterfully designed Alter Operator, blending area damage with team utility. She serves both as an accessible early-game option and a tactically rich choice for advanced compositions. Whether supporting cater-centric teams or creating defensive burn zones, she delivers multifaceted battlefield value.

For optimal performance with this ranged specialist, consider playing Arknights on PC via BlueStacks. The expanded battlefield view and precise controls perfectly complement skills like Ring of Hellfire, ensuring precise positioning and fluid execution.
