Battle Caster

Prerequisites: Ability to ignore arcane spell failure chance from armor, Base Attack Bonus +5

Benefit: You are able to wear armor one category heavier than you can normally wear while still avoiding the chance of arcane spell failure. For example, if you have the ability to normally wear light armor without incurring a chance of spell failure, you can wear medium armor and continue to cast spells as normal. This ability does not extend to shields, nor does it apply to spells gained from spellcasting classes other than the class that provides the ability to cast arcane spells while in armor.
