Brok

Siege Monster. Brok deals double damage to objects and structures.

Restless. At the end of his turn, if Brok has not dealt any damage to a hostile creature during his turn, roll 1d6. On a 6 he goes berserk for 1 minute. During this time he gains resistance to all bludgeoning, slashing, and piercing damage, and gains advantage on all strength based attacks. On each of its turns while berserk, Brok attacks the nearest creature it can see. If no creature is near enough to move to and attack, Brok attacks an object, with preference for an object smaller than himself. The effect can end early if he has destroyed the nearest object, or knocked the nearest creature unconscious.. Attacks against Brok have advantage while he is berserk.

Multi-attack. Brok makes two Crushing Hammer attacks.

Crushing Hammer. Melee Weapon Attack: +12 to hit, reach 10ft., 1 target. Hit: 21 (2d12+ 8) bludgeoning damage, or 28 (3d12 + 8) bludgeoning damage if the creature is a size smaller than Brok.

Earthshatter (Recharge 6). Brok slams his hammer down, creating a 30 feet cone in front of him. Any creature caught in this area, and who is touching the ground must make a Constitution save (DC 20) or be stunned until the end of their next turn.

Vengeful Swing (Costs 1 Action). Brok retaliates against a creature who attacked him last turn. He makes one Crushing Hammer attacks against them. The attack deals an additional (7) 1d12 points of bludgeoning damage for every 20 damage that the creature dealt to Brok last turn.
