Steel Watcher

Steel Watchers are a non-playable Construct race in Baldur's Gate 3. Steel Watchers are characterized by their imposing size and ability to self-destruct. They almost exclusively appear in the city of Baldur's Gate. Created by Enver Gortash to serve him. During the quest Disable the Steel Watch several Hellfire Watchers and a special Steel Watcher Titan can be found in Steel Watch Foundry. Karlach's heart is a prototype engine for the Steel Watchers. Three types of Steel Watchers are represented in the game:

With the exception of Steel Watcher Titan, Steel Watchers will gain the condition Detonation Impending! when they are close to 0hit points. This is caused by the passive feature Failsafe Protocol. The explosion will deal 4d12+26Fire damage in an area around the Watcher. This attack ignores resistance and immunity to Fire damage. Target will still take half damage on a successful Dexterity saving throw.
