Ignoring Arcane Spell Failure

[Saxavarius]

Is there a feat that allows a wizard to ignore ASF? I thought there was but  I can't seem to find it.

Nope. There are a few ways to do it, but they don't typically involve feats (unless you have another class which lets you ignore it in say light armor, then feats can expand that).

Still Spell.
Battle Caster can increase the weight class of armor you can cast in, if you already have some ability that lets you ignore ASF.
Alternative Spell Source let's you cast arcane spells as divine, which don't have ASF.
Twilight Mithril Feycraft armor with Thistledown padding can shave the ASF off all but the heaviest armor.

The Archmage PrC has a high arcana option that allows you to sacrifice a spell slot in order to use one spell as a spell like ability a few times a day - this removes ASF as there is no longer a somatic component.
