Ardelia

endgame support

support healer debuff nature

Ardelia brings powerful healing and debuffs. Her Talent provides team healing when picking up Shadows of Mr. Dolly, while her Combo Skill inflicts Corrosion to reduce enemy resistances, and her Battle Skill turns that into Physical and Arts Susceptibility. She fits in any team needing sustain and elemental debuffs, making her a top-tier support.

This endgame support build transforms Ardelia into a team buffer on top of her healing and debuffing. The Eternal Xiranite set grants a party-wide damage increase whenever she inflicts Susceptibility. Dreams of the Starry Beach further reduces enemy Arts resistance and boosts her own healing. With high Will and Intellect, she sustains the team while amplifying overall damage, fitting perfectly as the sole healer and buffer in any composition.

Insights

Core Mechanics

Eruption Column applies Corrosion, reducing enemy resistance. Dolly Rush consumes it to debuff with Physical and Arts Susceptibility.
<talent>Friendly Presence</talent> creates healing shadows on hit, and <talent>Mountainpeak Surfer</talent> allows an immediate second cast if Corrosion is present.

Scaling

Heals scale with Will. Early game provides solid sustain with low-investment gear; late game she shifts to a hybrid support with team damage amplification via the Eternal Xiranite set.

Team Role

Ardelia serves as a flexible sustain support who heals the team while debuffing enemies. Her Combo Skill and Battle Skill chain applies Corrosion then Physical and Arts Susceptibility, lowering enemy defenses significantly. Her healing, based on Will, is reliable and can be boosted by gear. In late-game, she can provide a team-wide damage buff via the Eternal Xiranite set, making her a core support in many compositions.
