Armor Abilities - Caster Armor*

Most common in magic-rich societies, some armorsmiths specialize in creating suits of armor specifically designed to the needs of spellcasters. Craftsmen occasionally create more flexible armor that allows for the complicated movements of somatic components. A suit of armor with this item quality reduces the chance of arcane spell failure by 5%, making it easier for a caster to wear without interrupting spellcasting.
Restriction: May only be applied to armor with an arcane spell failure chance.
Requirements: Craft Masterwork Armor, Artisan Craftsman
Price: +400 gp (light), +800 gp (medium), +1,000 gp (heavy); +7 to Craft DC of masterwork component.
Dragon #358
