The Destroyer

The Destroyer is a boss added by Defiled Lands. It can be summoned by using a Calling Stone on an active Conjuring Altar. When killed, it drops Defilement Powder and Ravaging Essence.

Its melee attacks, on top of dealing high damage, will send their victim in the air, similarly to Iron Golems. If its target is out of reach, it will perform huge leaps in an attempt to close the gap, causing an explosion as powerful as a Creeper's when landing. Those explosions treat most blocks as having a blast resistance of no more than 4, similarly to the blue skulls fired by the Wither. As the mob's health goes down, those leaps become increasingly faster.
