Ardelia

endgame support

supporthealerdebuffer

Ardelia earns a top-tier rating as a Nature sustain Supporter: she can debuff enemies with Corrosion then Physical and Arts Susceptibility, while her Talent provides reliable healing. Despite a low reroll rating, her healing, debuffs, and team-wide damage amp make her an all-rounder in many compositions.

This endgame support build turns Ardelia into a damage-amp sustain: the Eternal Xiranite set rewards her debuffing rotation with a team-wide +16% damage buff, and the Redeemer Armor off-piece accelerates Ultimate gain for more frequent healing. With Dreams of the Starry Beach increasing Arts damage taken and healing output, Ardelia simultaneously boosts team damage and keeps the party alive.

Insights

Core Mechanics

Ardelia's Combo Skill Eruption Column applies Corrosion to enemies, lowering their elemental resistance.
Dolly Rush consumes Corrosion to apply Physical and Arts Susceptibility, boosting incoming damage.
Her Talent Friendly Presence creates Shadows of Mr. Dolly that heal the controlled operator on touch; she can heal the lowest-HP ally instead if the controlled operator is full.
Her Ultimate Wooly Party deals Nature damage and has a chance to spawn more healing Shadows, enabling sustainable team healing.

Scaling

Healing from Friendly Presence scales with Will, making Will and Treatment Efficiency her most valuable stats.
She is strong from early game and only improves with the Eternal Xiranite set's team damage buff and the LYNX set's damage reduction.
Her debuffing potential (Corrosion into Susceptibility) makes her valuable even at low investment, but she becomes a true team enabler with endgame gear.

Team Role

Ardelia fills a sustain/debuffer slot in teams. She enables damage by applying Corrosion and then consuming it for Physical/Arts Susceptibility, and her healing from Shadows of Mr. Dolly keeps the controlled operator healthy. She fits well in endgame teams that want both survivability and a damage amp, as the Eternal Xiranite set lets her grant teammates +16% damage after applying Amp, Protected, Susceptibility, or Weakened. In pure survival comps, the LYNX set adds damage reduction on top of her heals. She can act as the main support in a wide range of team compositions, especially where sustained HP management and debuffs are needed.

Explanation

Eternal Xiranite's 4-piece effect is a natural fit because Ardelia constantly applies Susceptibility to enemies, activating the team damage amp.

The off-piece Redeemer Armor boosts Ultimate generation, so she can use her Talent-based healing more frequently.

Stanza of Memorials can replace the signature weapon if you want a team ATK buff, while Monaihe speeds up Ultimate recharges.

Notes

Uses Eternal Xiranite set to convert her Susceptibility application into a team-wide +16% damage buff for 15s.
Redeemer Armor is the off-piece for Ultimate Gain Efficiency, letting her cycle her healing Ultimate more often.
Dreams of the Starry Beach adds Arts Damage taken and improves her healing.
