I don't think 'exponential' means what you think it means.
of or expressed by a mathematical exponent.
"an exponential curve"
(of an increase) becoming more and more rapidThe idea your thinking about is quite linear.
arranged in or extending along a straight or nearly straight line.
"linear arrangements"
synonyms: straight, direct, undeviating, as straight as an arrow; sequential
"linear motion"
2.
progressing from one stage to another in a single series of steps; sequential
Actually, I think he's describing is quadratic instead of exponential or linear (it might look locally linear for small numbers such as the number of feats you can take depending mainly on how much synergy power each feat has), since the idea is (like the Abyssal Heritor example from 3.5) that each feat in the chain has its own power and then gains power depending on how many other feats you have. So if the initial power of each feat is X and then you add some fraction of that power for each feat in the chain/group counting itself (call it X/n), then you have the following progression in total power
1 feat: X+X/n, which is equal to 1/n*(X+nX). For ease, I'm going to ignore that 1/n because it's a constant. Assume it's there for all future lines.
2 feats: Each one has 2X+nX, together they have 4X+2nX
3 feats: Each has 3X+nX, together they have 9X+3nX
4 feats: Together have 16X+4nX
Z feats: Together have Z^2*X+ZnX
So it's going to be more quadratic in Z (the number of feats) the lower n is (in other words, the bigger the power you get from each feat when you add a new feat).
Have you looked at the Damnation Feats? Individually powerful and you get additional abilities for holding multiple feats in the set.

I love it when you all get geeky on me.
Thank you for amusing me endlessly, Mark!
Hmm
If you're not dead set on Elven Spirit I would suggest looking at Half-Drow Paragon and the Drow feats (provided you're DM will let you).
You would need a 13 Charisma at least to get down the Drow Nobility line which can grant you access to quite a few SLAs which can come in handy.
Detect magic ends up becoming Constant. The following SLAs end up at will. Dancing Lights, Deeper Darkness, Faerie Fire, Feather Fall, Levitate.
If you go 13 Charisma and Wisdom you can then get access to the 2 Umbral Scion feats which give you (eventually) 2 uses of Dispel Magic (or one of the other 2 SLAs), 1 use of divine favour and suggestion per day.
I personally think this is an interesting feat chain, maybe not for a wizard as much but more so perhaps a martial character even. Giving a fighter access to a lot of these SLAs is definitely interesting.
Yeah for sure. I didn't mention the Noble Spell Resistance just because I personally don't like it. It stops you from being healed if you need to be in a pinch. Yes you can lower your own SR as a standard action, but sometimes that may just be to long.
