You command your blades to protect you.

One of your blades start spinning around you, granting 2 + its enchantment bonus shield bonus to AC. Once per turn, per blade used, you may make an attack of opportunity against an attacker. These attacks count against your attack of opportunity limit. This is an exception to the no attacks of opportunity for the blades.

Augment: For every 2 additional power points you can bind an additional blade in the shield, granting another +1 to AC.

Focus: Controlled blades used
