Carcass - remnants of once a powerful demon that roam the nether wastes. A tough mini-boss with a variety of attacks. It can charge at you, spew blood, set entites on fire and summon skeletons to assist him in battle.

Upon death, Carcass spawns a Demonsoul that seeks for suitable vessels. It targets all types of skeletons and possesses them, creating a Revenant, stronger and faster skeleton. If demonsoul fails to find a shell to possess in 30 seconds, it explodes, turning nearby netherracks into magmanum ore.
Carcasses and Revenants drop demonbones that can be used with magmanum ore blocks to craft Bloodbranch and Magmanum sword.

Goblins now can "pick up" coins and share peace time with other nearby goblins.
