I took a look at the wizard set and found out that most of the bonuses that are on the set are already on the staff and some of the other bonuses are fairly useless for a wizard. Would it be possible to change the set bonus to give more useful bonuses like spell slots, crit immunity, some physical immunity or resistances, maybe a bonus to con for some ideas. Now I'm not going to post what is actually on the set bonus because that will give it away to those who havent acquired the items yet but I will say that it does need tweaking to become useful.

I fully agree that this set does need some altering if possible

The set is updated. You'll see changes on new items when you find them. The set bonus changes as soon as the next update is loaded.
