Need help with extra souls.

I am currently using this build: http://tinyurl.com/8b5j9ra

I want to be around 120-125. So I have about 23 soul levels to spend. The problem is I don't know what to spend it on. I was thinking magic or faith. But I'm not sure if it would be viable. I also wanted an AoE spell in the build.

Anyway could you make reinforce the character. And 28 str was a mistake, but I can't undo it now. But I am able to wield stronger weapons now. Anyway thanks!

If you put points into faith you may be able to use WoTG.
I say may because I don't remember the req. points. I'm sure someone can help with that.

It's 28, but should I use faith. Is it good?

It doesn't look like you'll be using buffs on stuff, so If you fancy Divine weapons it'll help a bit.

Crap, I can't do WoG because I killed Rhea Nico Vince and Petrus. Crap. I guess Pyro is the way to go. And I get faster castings.
