Some feats for the E6 wizard, with upward leanings. I personally strongly dislike the Sudden Metamagic feat chain, and prefer to see some use for the metamagic feats anyway. Secondly, I like the flavour these provide to specialists, and think feats for sorcerors should focus more on heritage and flavour (fire, ice, acid, water), than Wizardly Schools. There are quitre a few heritage feats for sorcerers floating around, so I shan't repeat them here.
WIZARDRY FEATS
==============

Benefit: For the purposes of range, duration, area of effect, the number of targets, and amount of damage, your caster level is regarded as one level higher when you cast spells from your specialist school. This does not affect the number of spells you may know, nor does this change the DC for the spells. (allows Evokers to do 4d4+4 with magic missile, or 7d6 with fireball)
