Weakening the Horror

SIDEBAR — Weakening the Carrion Hill Horror

Per EN World play reports and original module design: early PC choices determine
final encounter difficulty. Each surviving Keeper the spawn devours removes 2
"negative levels" (use drained conditions in PF2e). At adventure start the spawn
already consumed Baskerwhel and Marshan — 6 drained remain.

PCs who kill Myre, Hyve, and Crove BEFORE the spawn reaches them lock in maximum
weakness. Delay = building collapses, spawn grows, potential TPK.

Corporal instability (chaos beast in Crove's asylum) requires restoration,
remove curse, or heal heightening — stock Heggry's scroll cache accordingly.
