Mortal Shell 2 Harbinger
In Mortal Shell 2 the Harbinger is the frail form you inhabit between Shells. Week 1 notes even mention Zmey's tail grab hitting Shell and Harbinger together.

The Harbinger is the default body in Mortal Shell 2 — the weak form you play before claiming a Shell. Week 1’s Zmey notes say the tail grab used to take both the Shell and the Harbinger from full health to zero at once. That is official language, not a fan nickname.
How it plays
Reviews describe hatching weak and collecting eight Shells. Harden-style defense from the first game is not restated as a Harbinger-only move in the retail patch notes, so this page does not invent a kit.
When a boss note mentions the Harbinger, it usually means you are un-shelled or the grab hits both layers.
