Prestigious Spellcaster Feat Questions

So my question boils down to this:

According to Pathfinder SRD:

Prestigious Spell Caster gives you a +1 spells per day for the 1st level that you're prestige class doesnt provide that feature so long as it provides that feature at all.

You can take it multiple times, it increases your caster level by +1 up to the limit of you're level in the prestige class.

On the second time of taking this feat, is it suppose to give caster level or +1 spells per day?

As far as I know, a +1 caster level does not increase you're spells per day in the base class.

Which is correct?

It doesnt just increase caster level, it can be taken multiple times to offset prestige classes that skip spell levels.

I would hope that interpreting the feat as a half-strength trait would let common sense kick in as being incorrect. Poor wording/development aside, the intent of the feat is to make it so that you treat the entry of "—" the first time it appears on your prestige class as "+1 level of existing spellcasting class."

It's pretty clear that's how it works the first time you take it. I think his questions is what happens when you select the feat more than once because it says (under Special) that increases "effective caster level" by 1.

It stacks.

Hope that helps

this feat is giving you a level of a spellcasting level.

Jawsome! That makes ALOT of Prestige classes I had never considered before to be very worth it.

It astounds me how some prestige classes make it to print. The Blackfire Adept and Tattooed Mystic are both summoning focussed classes, yet they both lose 3 spell levels over their 10 level progression! Even one level needs strong powers to justify, so these prestige classes will rarely see play and be considered trap options.

Now we have a feat to fix the problem ... or does it? 4 feats are required to restore the lost spell levels, which for a character with no bonus feats, assuming they enter the prestige at level 6 or 7, is half the feats they get when they finish the prestige class at level 15-16. Factor in most prestige classes have feat prerequisites and that doesn't leave much.

So the question is, do the class abilities justify 4 feats, in addition to the opportunity cost of advancing your base class?
