Erma (Mad Scientist)
Erma, the Mad Scientist, is the Floor 3 / library-line boss (Steam achievement “This Is Not Stalking”). From Chapter 2 onward she can be replaced by Pantaxis, Guardian of the Library.
Fight structure (NamuWiki cross-check)
- About three phases involving a golem Erma pilots.
- Golem head and hands have separate hitboxes—wide attacks that clip multiple parts deal more effective damage.
- When golem HP depletes, Erma becomes targetable; deplete her HP to advance phases.
Key pattern note — dual lasers
Hands park top/bottom and scrape lasers across the arena while the head sprays. The clean dodge is to dash in the moment both lasers overlap and move the same direction (speeds are unequal). If tanky, sitting in the safer band and eating minimal chip can be better than panicking.
Weaknesses
- AoE that hits multiple parts.
- Status effects applied to any part count for the whole (freeze on a hand freezes the head; burns scale hard).
- High-damage runs often just delete the head first when full AoE is awkward.
