Santa-NK1

Santa-NK1 (also known as Santank) is a boss that makes an appearance during the Frost Moon. It acts similar to Mourning Wood, often chasing the target before stopping after a time to unleash one of three attacks.

When below half health, the face and beard of the Santa mask will be torn apart to reveal a rather deathly skull underneath.
