Nobody had the thought about itemizations in every ACT so far.
Why you might ask. Hmm, well it could be that every act you will need to reqeuip everything a new, because eevery transition all your gear will be lost and you will start the new act with standard equipment.
That way the itemization is a whole different thing and you can get overporwered items in every act which just get conventiontly lost at the start or just before the transition to next act.
Well done, every Act some hillariously overpowered god items and next act all the same again from start.
But dont be sad, you will have all your skills and level to be powerfull plus your tadpoles power too

Did i say it allready 3 times, every act new items again?
