The creature gains +2 to Strength and Constitution and +1 HP per level.
The creature is resistant to cold, poison, and necrotic damage and weak to radiant.
At the beginning of each turn in combat, the creature must make a DC 10 Wisdom save; on a failure, they will attack a living creature they detect randomly, regardless of friend or foe.
When killed by anything other than radiant damage, the creature will return to life with 1 HP, unless their corpse is dealt radiant damage. This can be done once per day.
