Darkness Dweller. Attacks made against a bezekira in bright or dim light have disadvantage.
Devil's Sight. Magical darkness doesn't impede the bezekira's darkvision.
Multiattack. The bezekira makes three Claw attacks. It can replace one of the attacks with a Bite attack.
Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) slashing damage plus 7 (2d6) fire damage. The bezekira deals an extra 28 (8d6) fire damage when it hits a target with an attack and has advantage on the attack roll.
Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage, grasping the target with its mouth. If the target is a Medium or smaller creature, it has the grappled condition (escape DC 17). The bezekira can't make a Bite attack while a creature is grappled in this way.
