If this is already in game: sorry I'm dumb. I haven't seen it yet.

Often I find a piece of armor that has magic effect rolls that would be really good for me, but it's the wrong armor type (AKA it's sorceror). I think it would be cool if there was an orb with a really low drop chance that can randomly re-roll armor type (heavy, bruiser, rogue, sorceror). It would also require some knowledge on the part of the player to be used effectively because magic effects that are restricted to certain armor types would be re-rolled as well.
