An idea would be a new ritual for the magic circle where the sorcerer uses let’s say something like a fragment of power and soul essence to power themselves up. It would give a buff for 5 minutes where the effects of corruption are held at bay. So full HP/Stam. I don’t think this will be long enough to run an entire dungeon or hunt someone down in PVP but could be a good way to defend your lair if you’re being raided in pvp.

I liken it to when Yoda fought Count Dooku he drew upon the force to augment his frailty then once the fight was over immediately reached for his cane.
