Mystical sigils line the hems of this bulky, thick-shouldered robe. Minuscule gems adorn the cuffs, collar, and hems.

A robe of arcane might grants you a +4 armor bonus to AC. In addition, each robe is attuned to one of the eight schools of magic, chosen during creation (and identifiable with a successful DC 20 Spellcraft check).
When casting a spell from that school, you gain a +1 competence bonus to your caster level.

Prerequisites: Craft Wondrous Item, mage armor, specialist wizard in the relevant school.
Cost to Create: 10,500 gp, 840 XP, 21 days.
