it is a bit diferent.
The wither is a floating, three-headed, ghostly mobster that looks like an skelleton
this one has a lot of diferences with the ender dragon
as this one has to be sumoned, that can be acomplished by geting 3 wither skull heads and
4 blocks of soul sand.
the other thing about this guy is that he trows you explosive heads that cause masive destruction,
It also breaks obsidian on his way out so I´m telling you this guy is though. I also flies so it would be a great idea to chase him with arrows first but after he has half life he generates a shield against them so you will have to figth him in close combat.
well folks thats my review in the new boss called the wither thanks!
Au Revoir mes amies.
