Neat Trick for Wizards with casting more high lvl spells per day

[Ramza00]

It's not incredibly cheesy or anything; you have to blow ALL of your feats (and I'm almost entirely sure that you can't trade Elven racial proficiencies for full feats; and that if you can by the letter of the rules, any DM who would let you has a hole in his head) to get 3 extra spells per day. I mean, it's a good effect, but it's hardly some game breaking rules loophole.

By the letter of the rules yes you can switch out those feats. I agree very little if not all DMs will say no to the Elven Racial Profiencies. The "cheesy part" was the elven Racial Profiencies.

I also said before in the build that if you don't use that, it isn't that good for it takes all your feats.
