He is a stubborn player. In the campaign we are playing in, I have decided that instead of giving players feats on their normal levels, they get them on the same levels that fighters get bonus feats. HE decided he didn't like that feat system and is opting out in favor of the old ways...
With that said, he wants to be a spellwarp sniper, he wants to do mad damage. He thinks he has to be level 18 to achieve this.
By similar spells, I meant AoE that deals damage based on caster level... Fireball, lightning bolt, cyclonic blast, wings of flurry, etc.
Also, I am allowing the book of erotic fantasy if any of you are familiar with it.
