Not sure this is the right section for this, but it was the best I could come up with. I thought I remember reading somewhere that Elder Guardians & the Wither are now counted as a miniboss fight, or something like that. I believe there may be tokens or something else involved. My main question is, does the Wither behave any differently on EMC than in vanilla survival? I couldn't find anything on the wiki ( I probably was in the wrong sections). Thanks for any help.
On difficulty 5-, it is a vanilla wither, but on difficulty 6+, it teleports around, regens, does more damage, etc.
Chance for more tokens and more than one star. I would assume that the chance for a second star is 20(n-5)%. All I know is that diff 5 guarantees one, and diff 10 guarantees two. However, if you beat one on 10, I think you'll be happier that you actually beat it than the fact that you got another star.
