Extraction Round

Extraction Round [CURRENT] (server-authoritative)

Rule	Value
Round duration	600s (10 min)
Safe-zone (circle) starts shrinking	at 300s (5 min); radius scales with remaining time
Storm damage (outside the zone)	25 HP/s to your active monster (not while in an instanced fight)
Portal spawn interval	every 30s after the 5-min mark, inside the closing circle
Encounter radius	44px (walk this close to a monster → fight)
Extract radius	48px (step this close to a portal → extract)
Extract (victory)	run ends, keep gains, active team healed to full, run-found chains banked
Defeat (team wiped by storm, or timeout)	lose the active run team (Q10) and any run-found chains. Vault + banked chains kept; team refills from the vault, or 4 random Lv.1 starters if the vault is empty.

Q10 still OPEN: the death penalty above (lose active team, vault safe) is the current behavior and my recommendation, but not yet confirmed — see docs/REQUIREMENTS.md §4.
