Corrupted Orc

Suicidal. Having no self preservation and a severe lack of intelligence, corrupted Orcs are unable to be intimidated and will attack the closest target it sees, even if it means certain death. 

Greataxe. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (1d12 + 2) slashing damage.

Black Bile. Ranged Attack: +5 to hit, reach 5 ft. or range 20/30 ft., one or multiple targets. Hit: 6 (2d6 + 2) acid damage. 

Aggressive. As a bonus action, the orc can move up to its speed toward a hostile creature that it can see.

Reactive. As a reaction, due to their low intelligence, any creature that attacks the orc (unless it is overwhelmed) will instantly be targeted, moving at 10 feet toward its target and forgetting the first hostile it was targeting previously. 

Overwhelmed. As a reaction, once 8HP or below, this orc will become enraged and can use its bonus action. All players must roll a D20, the lowest roller is then targeted. The corrupted orc can then attempt an attack with it's Greataxe with disadvantage.
