Make it so on top of it’s sound effects it also summons the actual butcher on hit. Have it summon the boss for 30 out of 60 seconds. It would be a buffed version of maximus. It could have the draw in and other special abilities(I assume spead up.) and good damage etc.
It could be really fun on my follower.
Maybe on it killing something it adds time to it’s spawn time to stay active.
