Indomitable. Skarmen can reroll any failed DEX, STR or CON saving throw. He must use the new roll, even if it is worse.

Posessed. Skarmen is immune to any mind altering spell such as charm, mind control or similar spells. The demons grip is to tight on him.

Unnaturally Athletic. The Demon gave Skarmen his remarkable skills as an athlete back. He is as athletic as he was in his prime. He can add +2 to any STR, DEX, or CON check you make that doesn’t already use his proficiency bonus and when he make a running long jump, you add +5 ft. to the distance.

Sentinel. When Skarmen hit a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn.

Sentinel(Costs 1 Actions). Skarmen can Take the Sentinel Attack reaction instead of a legendary Action once per turn without using his reaction.

Legendary Resistance(Costs 1 Action). Skarmen can use one of his Legendary Actions to automatically pass a failed saving throw. This does not stack with his Indomtable trait.

Siphon Life(Costs 1 Action). Skarmen can use one of his Legendary Actions to heal 1d10+12 if he is within 5 ft. of a character who is either dead(and not reanimated as a undead) or lays down dieing. If the character lays down dieing, he automatically fails one death saving throw.
