Undead Fortitude. If damage reduces Adam to 0 hit points, he must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, Adam drops to 1 hit point instead.

Undying. Adam does not age. He always appears to be a goliath in his early 30s. Additionally, he does not need food, sleep, or air.

Unholy Strength. Adam has advantage on strength saving throws. Additionally, he may activate this feature to give himself advantage on a Strength (Athletics) Check. He may use this feature up to 6 times, and regains 1d4+2 uses each dusk.

Affront to Nature. Adam loathes his own existence, as well as that of all undead, but he abhors his creator most of all. Should Adam ever gain free will, either by Dr. Hyde relinquishing his soul to him or it being forcefully rested from Hyde, he will immediately begin plotting to destroy Hyde. If he is successful, or he discovers that Hyde is already dead, Adam must succeed on a DC 20 wisdom saving throw or take 10d12 Psychic damage. If this reduces him to 0 hitpoints, he dies. If Adam succeeds, he pledges himself to the scourging of the undead from the material plane.

Multiattack. Adam makes two attacks instead of one when taking the attack action.

Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d6 + 4) bludgeoning damage.

Greataxe. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 16 (2d6 + 8) Slashing damage (Silvered)
