Grobbulus, the second raid boss of the Abomination wing of Naxxramas as a skin to the Butcher, to describe how this will work,
- his cleaver arm will be replace with a blunt-looking hammer/mace/fist weapon while his sickle arm’s the slime injector
- fresh meat passive will collect sludge and a pile of sludge for hero take down
- Hamstring will have him slam the ground with his blunt-like arm
- Butcher’s brand causes his injector arm to leak slime
- Ruthless onslaught will cause him to leave behind a very short trail of slime or just be a regular charge
- Lamb to the Slaughter will throw in a naxxramas style pillar with chains
- Furnace blast will cause the area around butcher to have cracks that glow green " similar to Heigan the Unclean" and explode with a splash of slime
- When he collected 200 sludge/blood, his slime tube will begin to glow.
- the skin will make the character silent but will still make sounds with abilities like Ruthless Onslaught or Lamb to the slaughter slam so that opposing teams still know the warnings, if not that, then a sound of flowing slime.
