Construct Traits: A captured one bugbear 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. The common raggamoffyn component cannot heal itself but can be healed through repair; the bugbear component heals normally. It cannot be raised or resurrected. A captured one bugbear has darkvision (60-foot range).

Senses: Both components of the captured one bugbear see and hear everything the bugbear can.

Shared Damage (Ex): An attack on a captured one bugbear deals half its damage (rounded down) to the raggamoffyn and half (rounded up) to the bugbear.
