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 maximizes Ardelia's healing potential. The LYNX set significantly improves her single-target heals and grants a defensive buff, making her ideal for content where survival is critical. The weapon still contributes to team damage through susceptibility application.

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.

Explanation

Dreams of the Starry Beach increases healing and provides additional damage amp for the team.

LYNX set grants +20% HP Treatment Efficiency and applies DMG Reduction to healed allies, boosting survivability.

Notes

LYNX set DMG Reduction buff only triggers on controlled operators, not on passive healing from stage effects.
Focuses purely on maximizing healing output and survivability.
