Jalkain said:I think the previous poster was making the point that a single feat will outperform the class ability when it comes to taking arcane castings PrCs that don't advance your familiar (which is virtually all of them).
As a random example, a Bard 7/Incantatrix 3 WITH the feat would have a familiar caster level of 10, whereas a Wizard 7/Incantatrix 3 WITHOUT the feat would have a familiar caster level of only 7. One feat allows the bard to go from having no familiar to having a better familiar!
I think the previous poster was suggesting that it should be split into two feats to avoid this situation.
Your interpretation is correct. I have no objection to a feat that allows an arcane caster class that does not normally get a familiar to now obtain one. I also have no objection to a feat that allows class levels that would not normally stack for this purpose to now be combined. I *do*, however, object to one feat that does both.
