BOSS GUIDES

Grym is Act 1's adamantine golem boss in the Grymforge — a 300 HP construct that's immune to nearly all damage unless it's standing in lava and gains the Superheated status. The key to victory is using the forge's massive anvil to crush it for 100 damage per strike.

PRO TIP

Take a long rest before the fight and ensure someone has Command: Approach prepared. This spell lets you lure Grym into position without risking a counterattack. Also prepare Heat Metal if available — it applies Superheated status even without lava.
