Splits incoming damage over time and raises Max HP. Pair it first with Hump and Regenerative Tissue and test that relationship in the Spines Reflect route. Plating or delayed mitigation does not make no-hit conditions safe.

Impervious quick answer
Impervious is a defensive layer, not proof that no-hit achievements are safe. A July 19, 2026 Steam answer now makes one boundary clear: even plating loss breaks Zen or no-hit attempts.
Use it for chonk, defense, and pressure survival, then still watch for delayed-damage edge cases instead of assuming the shell preserves achievement credit.
