Bracers. Voidwalker wears a pair of magic bracers that have AC 15 and 15 hit points. If a voidwalker loses both of its bracers, it must succeed on a DC 17 Charisma saving throw or return to its home plane as if affected by banishment spell. If it succeeds on the save, it, however, has disadvantage on Strength, Dexterity and Constitution ability checks and saving throws.

Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) bludgeoning damage. If the target has an Intelligence score of at least 3, it must make a DC 13 Wisdom saving throw. On a failed save the target is unable to make melee attacks (including opportunity attacks) against anyone but the voidwalker until the start of the voidwalker's turn.

Consume Shadows. If a voidwalker is in an area of total darkness, he can draw the darkness itself and regain 7 (1d8+3) hit points.
