Construct Traits: A dread guard is immune to mind-affecting effects, poison, sleep, paralysis, stunning, disease, death effects, necromantic effects, and any effect that requires a Fortitude save unless it also works on objects. The creature is not subject to critical hits, subdual damage, ability damage, ability drain, energy drain, or death from massive damage. It cannot heal itself but can be healed through repair. It cannot be raised or resurrected. A dread guard has darkvision (60-foot range).

Dread guards attack mindlessly with their weapons. They are unsubtle and straightforward in combat.
