Ardelia

endgame support

support debuff healer

Ardelia is a Nature sustain character who applies Corrosion to reduce enemy resistances and then inflicts Physical and Arts Susceptibility to amplify damage. Her talent creates healing pickups, and her Ultimate provides team-wide healing. She fits many team compositions as a versatile support.

This build turns Ardelia into a powerful team buffer and sustainer. The weapon and gear work together to amplify enemy weakness while increasing her healing output. The off-piece armor ensures she can use her Ultimate more often, providing consistent healing and damage support.

Insights

Core Mechanics

Combo Skill applies Corrosion on final strikes to lower all resistance.
Battle Skill consumes Corrosion to apply Physical Susceptibility and Arts Susceptibility, boosting team damage.
Ultimate spawns healing pickups (Shadows of Mr. Dolly) that restore HP based on Will.
Talent Mountainpeak Surfer allows a free recast of Battle Skill after consuming Corrosion.

Scaling

Healing scales with Will, making Will a key stat for sustain.
Early game benefits from flat Will and Treatment Efficiency; endgame builds focus on HP and team buffs.
Team-dependent for Corrosion setup (requires controlled operator to land final strike).

Team Role

Ardelia excels as a secondary support and debuffer. She provides resistance shred, damage amplification, and sustained healing over time. Her playstyle is semi-passive: she relies on the controlled operator to trigger her Combo Skill, then follows up with her Battle Skill. She fits comfortably in teams that need both survivability and enemy debuffs, and can work alongside other healers or damage dealers.
