Colton B. Rotten

Dead He's basically immune to becoming dead, since he already is dead. He can only be disabled, meaning if his hitpoints drop to 0, he's still technically alive. This creates a comical scenario where you can decapitate him, but still keep his talking head.

Attack If you made him angry

Knife Melee Weapon Attack: +2 to hit, reach 5 ft., 1 target. Hit: 1 (1d4 + 3) [piercing] damage. 

Revolver Ranged Weapon Attack: +2 to hit, range 30/150 ft., 1 target. Hit: 1 (2d10 + 1) [piercing] damage.

Necro-bullets Ranged Weapon Attack: +2 to hit, range 30/150 ft., 1 target. Hit: 1 (1d12 + 2 [necrotic] damage. Target must make a wisdom saving throw or become petrified.

Frenzy  Colton has a high temper, and he can go off in a fit of fury. When he does, he gains +1d8 on his melee attacks.

Call to Arms  Colton summons 2-3 skeletal scoundrels to attack the nearest player. They become last in initiative order.
