This is Deathbed. Deathbed was forged from the intense pressure of bedrock. It spawns in a bedrock temple across the map in rare locations. It is a fierce fighter with sharp claws to melee its victim. It moves underground for defence and stealth. Its tough skin makes it a hard fought battle. Once Deathbed reaches half health it releases its inner soul and releases waves of silverfish. This is its defence mechanism. Once you have defeated Deathbed it has a chance of dropping 1-2 wither skeleton skulls and a random disc drop. Also inside Deathbed's temple you'll its stash of materials. This fight is hard but well worth it in the end.
