shilsen said:That feat only raises caster level, right? If earlier responses on this thread are correct, it does not actually raise the character's level where spells per day is concerned. So a Ftr4/Clr5 with the feat would have a caster level of 9 but would have the same spells per day as a Ftr4/Clr5 without the feat. IMO, that makes it a strong feat, but not an overpowered one.
You're correct on its effect. Sure, you don't have as many spells per day, nor access to higher level spells, but in one stroke you've catapulted all level-variable effects of the spells you do have (range, duration, damage dice) and your ability to penetrate SR by up to 4 levels! This is potentially game-breaking for the multi-classed sorcerer or wizard, particularly if taken in conjunction with a PrC specifically designed for multi-class characters (e.g. arcane trickster or spellsword). Any player in my campaign who even dares to ask if they can take this feat gets an insta-xp-penalty!
