Wow, a sorcerer changing his spells is a pretty major effect imho!!
Think about it: take limited wish and you suddenly know any lower level spell that you want. You just have to burn 300 xp to do it.
About to face a demon? Suddenly, you know dismissal.
About to enter extremely important negotiations? Suddenly, you know eagle's splendor. (Assuming you don't have an item of +4 cha by now.)
Need to get away before the relentless walls crush you? Teleport.
Ad infinitum.
