Arcane Transfiguration
Pre-Requisites: Item Reprieve, Spell Reprieve, specialist wizard level 10th
Benefit: Choose a school of magic that was previously prohibited to you because of your arcane specialization. You can now learn and cast spells from that school normally, as if you were not a specialist wizard.
Special: You can select this feat only once. The school you choose must be one for which you have already taken both the Spell Reprieve and the Item Reprieve feats.
Yes, it has 2 feat pre-reqs. Depending on how you interpret the Pre-Requisites line, you may not even qualify for this feat with most of the Wizard builds we do around here (what with them jumping out by level 5 and all). Item Reprieve is generally better if you don't want to attempt dumping of massive skill ranks into UMD just to have a decent chance of using Wands, and Spell Reprieve can get you specific spells that are so awesome that you just have to have them. If you still just want specific spells, then perhaps Item Reprieve + an appropriate Runestaff can get you the stuff you want.
