Bone Golem, Lesser

Berserk. Whenever the golem starts its turn with 20 hit points or fewer, roll 1d6. On a 6, the golem goes berserk. On each of its turns while berserk, the golem attacks the nearest creature it can see. If no creature is near enough to move to and attack, the golem attacks an object, with preference for an object smaller than itself. Once the golem goes berserk, it continues to do so until it is destroyed or regains all its hit points. The golem’s creator, if within 60 feet of the berserk golem, can try to calm it by speaking .rmly and persuasively. The golem must be able to hear its creator, who must take an action to make a DC 15 Charisma (Persuasion) check. If the check succeeds, the golem ceases being berserk. If it takes damage while still at 20 hit points or fewer, the golem might go berserk again.

Immutable Form. The golem is immune to any spell or effect that would alter its form.
Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.

Magic Weapons. The golem’s weapon attacks are magical.

Multiattack. The golem makes four melee attacks. Scimitar +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.
