The Dark Emperor

The Dark Emperor is a Tremode boss.

Spawn
The Dark Emperor will not spawn on its own and can only be summoned with an Emperor Crown during night.

Behavior
It acts like the King Slime, but much more powerful and intense.

Phase 1

 * He has a similar AI to the enhanced Giant Mimic, therefore dealing heavy damage and jumping around.
 * He also occasionally sits still and will deflect all projectiles the player throws/shoots and then dealing increased damage. (does not include certain magic weapons)

Phase 2

 * He flies around and summons Falling Dark Servants which, upon reaching the ground, turn into regular Dark Servants.
 * He also can spin around, summoning a barrage of Falling Dark Slimes which have the same effect as the Falling Dark Servants, but turn into Dark Slimes instead.
 * He also occasionally stays stationary in the air.
 * In both Forms, he spawns his Slime Minions, but in the second form, he tries to launch them directly at the player.

Expert Mode
It's stats are highly increased.
