Press the flag. I made a song. You can use it if you want to.
This is the Death King. His first attack throws heat-seeking skulls at the player. His second attack throws a scythe at the player like a boomerang. It goes at the player, then it comes back at the player again. When he gets low health, he will summon skeletons that throw bonerangs. The Death king is very strict and wont take no for an answer. He is also mean.
