Poltergeist
Who is Poltergeist?
Poltergeist is a 4-star Spirit-afflatus tank who is extremely hard to kill and serves as a dedicated damage absorber against Reality DMG-heavy enemies. Her Insight I passive grants [Concealment] at battle start — dodging all non-Ultimate Reality DMG for 2 rounds. Her Ultimate applies [Taunt] to herself, reduces her DMG Taken, grants DMG Heal, and re-enters [Concealment] for one round. She can also apply a -35% Mental DEF debuff to enemies, giving her a sliver of offensive support utility. Outside of Reality-heavy content she provides very little for the team beyond staying alive.

🔮 Best Relic / Echo Set
Resonance: HP% is the top priority to maximise her durability and reinforce the DMG Heal scaling on her Ultimate. Some ATK% helps her Skill 1 Mental DEF debuff land meaningfully.
⚔ Best Light Cone / Weapon
The Fighter's Best Wishes (prydwen recommended): 16% HP and 10% DMG Taken Reduction at below 60–80% HP — stacks perfectly with her innate DMG Taken Reduction and DMG Heal for maximum tankiness. Approaching Rain (alternative): 10–20% DMG Heal after Ultimate and 18% Incantation Might — reinforces her post-Ultimate sustain cycle.

Frequently Asked Questions
What does [Concealment] do?
[Concealment] causes Poltergeist to evade all non-Ultimate Reality DMG attacks for the duration. She will not take damage from those attacks at all — they simply miss. This makes her nearly invulnerable against Reality-type enemies in the early rounds of a fight.
Why use Poltergeist over a healer?
In Reality-heavy content she provides guaranteed damage avoidance through [Concealment], which is stronger than conventional healing against predictable high-damage hits. However, she offers no healing, offensive buffs, or damage herself, so a healer is usually more versatile.
Does her Mental DEF debuff help Mental DMG carries?
Yes — the -35% Mental DEF debuff from Skill 1 is a useful side effect if you run Mental DMG characters. It is not the main reason to use her but it adds incidental team synergy in mixed compositions.
