Ardelia

early game 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 is a budget build that focuses on maximizing healing through Will and Treatment Efficiency. The gear is easy to obtain and effective for early-mid game content. The weapon provides additional support by healing a second ally.

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

Early game, Will is the most important stat for healing; both weapon and gear provide Will.

Mordvolt Resistant set's low-HP bonus helps in tight situations, but generally her healing is sufficient.

Fluorescent Roc can also be used for more Will and ATK, but Freedom to Proselytize offers better utility.

Notes

Freedom to Proselytize provides additional Will and a secondary heal target.
Mordvolt Resistant set grants flat Will and a conditional Treatment Effect bonus when HP is low.
