Crypt Stalker

Perpetual Decay. At the start of it’s turn, when not in Direct Sunlight, the Crypt Stalker will regain 15 Hit points. If the Crypt Stalker takes Fire or Radiant Damage then this trait doesn’t function at the start of its next turn. 

Undying horror. If the Crypt Stalker drops to 0 Hit points within 5ft of a tomb, grave or crypt, it will draw necrotic essence from the site and restore 10 Hit points at the start of its next turn. If the Crypt Horror takes any Radiant or Fire Damage then this doesn’t function and it will die. 

Multiattack. The Crypt Stalker makes 4 attacks, three with its Distended Claws and one with its Bite.

Distended Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., 1 target. Hit: 13 (2d8 + 4) slashing damage. 

Bite. Melee Weapon Attack: +8 to hit, range 5 ft., 1 target. Hit: 16 (3d8 + 4) piercing damage. The target must make a DC13 Constitution Saving Throw or take 2D6 Necrotic Damage. 

Paralyzing Wail. In place of a bite attack, the Crypt Stalker may release a Paralyzing Wail. Every creature within 30ft must make a DC15 Wisdom Saving Throw, on a failed save, the target is Paralyzed for One round. On a successful save, the target is immune to the effects for 24 hours.
