This is the 3rd mob in the Paradox storyline. He is one of the weaker mobs in the storyline with only 1,000 HP (500 <3). There are no cutscenes for this boss fight, as its another straight forward fighting round in the paradox. When Deaths' Wither is killed, he will drop Death's Collar Of Command, 2 Nether Stars and a Reapers Gem, the only tool that can craft Reapers Blade. Also, another obsidian pillar identicle to the one from the Death (Human) fight will pop up.
