Slime of The Underwrold

The Slime of the Underworld is a hardmode boss with 15,000 health. However, it cannot be damaged until it's 4 giant lava slime minions have been killed. Their health is intertwined, at 35,000. The giant lava slimes summon unstable lava slimes, which will fly, shoot spikes, and charge at the player. Their health is intertwined with their masters. The giant lava slimes will shoot deadly homing projectiles dealing 200 damage. Another attack is where one will summon 5 unstable lava slimes, then teleport to the player and attempt to hit it with what appears to be a giant hammer. If the player is hit, the hammer will deal 1000 damage. If they player does not get hit, then the extra unstable slimes will despawn. When they reach 10,000 health, they will split in half, each one as powerful as it's parent. Upon their death, the slime of the underworld itself will attack. (note to self, finish later)

Notes:

 * I was originally going to name it "the slime of cuthulu" until I learned it was against the rules.
