Champion set plus a good weapon would suffice, though you can make an actual build. Assasin - abuse earth weakness with vanish, smoke bomb + vanish away to safety. Shaman - fly around the arena and whenever he teleports really close to your totem just aura spam him, though be careful and pay attention to your mana . The aura prison will keep him from teleporting but if you're not careful enough he will 2 shot you. I'd suggest using October Fires as a weapon. Mage: Meteor - teleport repeat (who cares about ice snake when he can yeet into your face). If you're hit then just cycle teleport - heal back to full health. Archer: don't bother using arrow storm, your main concern should be to arrow bomb him from a safe distance, so you'll need good reactions to escape away when he teleports near you. Warrior: Good luck lol.
