Poltergeist — Review & Analysis
Poltergeist is a 4-star Spirit single-target unit built around dealing Mental DMG while sustaining herself. Incantation II grinds down the target's Mental DEF (25-35% over 2-3 rounds), while Incantation I carries a high penetration rate (up to 40%), letting her bite through thick single-target defenses. Her ultimate is a self-only defensive tool — she enters Tauntto soak aggro, cutting her own DMG taken and boosting healing on herself, on top of an opening Stealthfrom her passive. That makes her a single-target sub-DPS/debuffer who can look after herself.
- Incantation II lowers the target's Mental DEF by 25-35% for 2-3 rounds, amplifying single-target Mental damage from both herself and allies.
- Incantation I has a high penetration rate (30%, up to 40% via Shaping), ideal for shooting through thickly-defended single targets.
- Her ultimate's Tauntplus reduced DMG taken, increased healing and an opening Stealthgive her solid self-sustain without needing a babysitter.
- As a Spirit unit she stands outside the Afflatus counter cycle, countering nothing.
- As a low-tier 4-star, her base stats and power ceiling clearly fall behind rarer units.
- Her entire kit is single-target with no AoE and thin team utility — and her ultimate only protects herself, offering no shielding or healing to allies.
- Being a Spirit unit, she stands outside the Afflatus counter cycle, so no enemy type gives her a matchup edge either way.
Level Incantation II first to maximize its Mental DEF reduction and debuff damage — that is her core value; then raise Incantation I if you want to lean on the penetration for personal damage. The ultimate only needs to progress through its Shaping thresholds to deepen her self-sustain. For Psychubes, since she handles her own healing, pick ATK/crit or single-target damage options to push her damage output rather than a healing Psychube.
