New boss: Dripstone Nightmare

The dripstone nightmare is a terrifying creature made of dripstones, with sharp dripstone teeth, long arms, and dripstone claws.

Stage 1: The dripstone nightmare is stuck in the wall, but its arms are still mobile. The arms will hover around the arena and have three attacks; the first attack is the hand will slam the ground and cause stalactites to fall from the ceiling, the second attack is the claws scratching you, and the third attack is the claws will grab you and put you in the dripstone nightmare's mouth, dealing major damage. If you attack the claws while they're attacking, they will break and can't attack, but they will regenerate in 30 seconds. If you approach the nightmare's face, the hands will block you, but if you break both of them, the nightmare's face will be vulnerable.

Stage 2: The dripstone nightmare will stick its hands in the ground and cause stalactites to fall constantly for this entire stage. It will summon mobs and make stalagmites come out of the ground in various patterns that you must dodge. After 3 waves of stalagmites occur, the dripstone nightmare will become tired for 5 seconds, when you can safely attack its face before the cycle repeats.

Stage 3: The dripstone nightmare will break free from the wall and walk around the arena. Its hands will attack like in stage 1, but much more aggressively. The nightmare itself can also stomp if you're too close, which deals great damage and causes stalactites to fall from the ceiling.
