Well, my advice worked, but then IC had to get all legal grey-area-y and post it. So new subject, smetzger style, to make this legit:
That is a really powerful feat. Dang. So is it overpowered?
It grants you the ability to limit break the planer binding spells by 2, when the only other way to do that iirc (granted, its by 4) is the Cosmic Descrier EPIC PRC.
It grants you a +2 to spellcaster level of certain things. Almost comparable in power to the domain abilities that grant +1 to a somewhat broader range of spells (Evil, Good, Cures)
A limited spell focus on binding spells
hmmm....
PS: Cool feat, altohugh possibly overpowered. The posting of this feat actually increased my desire to buy RoF
