Actually I heard Diamonds might be used in a quest something to do with the Helsik ritual? If not then there maybe a trader in act 3 that buys them for more than usual. Can anyone confirm any of what I said?
No replays unless all games have a new game+ to carry over everything I earned in the first playthrough, and only levels carried over if the new game + has higher level caps. Oh and make enemies harder and drop way better items, to make up for the wealthy start
