Ms. Moissan — Review & Analysis

Ms. Moissan

Ms. Moissan is a 4-star Mineral unit built around single-target Reality DMG, with a clear off-support streak on the side. Her Incantation I hits one target and scales up to 550% through Molding, while her Ultimate both nukes and inflicts [Frozen], locking the target out for a round. Add a team-wide ATK-based [Shield] and self-healing after every action, and she reads as a hybrid single-target DPS with survival tools — though her F tier means stronger picks tend to crowd her out.

Strengths
  • Single-target Reality DMG that scales up to 550% through Molding, plus a +10% Penetration on battle entry to help her hits punch through defenses.
  • Incantation II grants the whole team an ATK-based [Shield] (up to 200% ATK for 2 rounds) — genuine protection for the full lineup.
  • Her Ultimate applies [Frozen] to lock the target down, and self-healing 40% of ATK after every action gives her solid self-sustain.
Weaknesses
  • Her Mineral afflatus is countered by Star, so she takes extra damage and deals less into those matchups.
  • The [Frozen] from her Ultimate is removed the instant the target takes a Mental DMG hit, so her control easily gets wiped by Mental-damage teammates; on top of that every skill is single-target with no AoE, and her F tier makes her easy to replace.
Build Priority

Prioritize Incantation I first — it's her main damage source and Molding pushes it up to 550% — then her Ultimate to maximize single-target burst. Since ATK is the shared stat driving her damage, [Shield] thickness and healing alike, an ATK-leaning Psychube (with some crit) pays off for both her offensive and defensive roles; if you run her more as a protector, invest extra in Incantation II for a beefier shield.
