I think the category would be better if you had to kill the NG+ 28 33 orb boss, it's a bit silly going all the way to NG + 28 only to not kill the boss, which is the main reason most people go to NG + 28 in the first place. It also feels like it gives the run a better conclusion.

Yeah, totally "shifty eyes"

Seems like a fitting change. I'll make an unilaterally decision of implementing this as a requirement. Especially considering the 33orb category neccessitating it, while NG+28 currently not.
