Slam

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage.

Use Magic Item (Recharge 5-6)

The kalke activates a magic item in its possession and can ignore all class, race, and level requirements on the item. The kalke must make a DC 11 Intelligence saving throw. On a success, the item activates normally. On a failure, the item doesn't activate and can't be used again until the next dawn. If the kalke fails the saving throw by 5 or more, it causes a magical backlash. Each creature within 5 feet of the kalke, including the kalke, must make a DC 11 Dexterity saving throw, taking 5 (2d4) force damage on a failed save, or half as much damage on a successful one.
