Equipment specific pets is probably the most useless Idea ever for SMN. Because as we now SE it would be like only 10 charges a "staff" and has a droprate of maybe 0.00001% @ Provenance Watcher or something like that. Oh and if you change that Item you lose the avatar *dum dum dummmmm*. Avatar's should stay spells obtainable through quests.

The first and most pressing matter is still to fix the existing Avatars and the BP mechanics anyway.
