This add-on turns the swamp biome into something much more dangerous to explore since sometimes you’ll find the Magician Supreme Boss wandering around there. Even though he has a striking resemblance to Santa Claus you will do best to avoid him at any cost since he is very dangerous and will ultimately try to kill you. The Magician Supreme Boss can be found by going into a swamp biome and search for a witch hut and that’s because they replace witches. It is very dangerous and you should never approach one unarmed or without wearing any protective gear.You really have to plan your attack carefully since it has wide variety of attack styles. It can shoot fireballs, shulker projectiles, dragon balls and throw poisonous potions with lingering effects. Every once in a while it also summons wither skeletons which will fight for their master.
