so what new gear is the best for classes and what of the 11 new dungeons can i do without 8/8 (what are their difficulties?)

There`s the oryx is awesome set for the knight, which is just reskinned tops, the swoll paladin set, which looks really nice and does tons of damage. The twilight archmage set, which has a piercing spell and funky shot pattern. The geb set for priest, which gives him a huge buff.

All of the sets transform your character into a new sprite when fully equipped.
