PC on Perfect Air Staff req 8 10/10

Just wondering what this kind of thing might be worth, I have no idea myself.

Insightful Air Staff of Defense
Energy +10
Lightning Dmg: 11-22 (Requires 8 Air Magic)
Halves casting time of spells (Chance: 10%)
Halves recharge time of spells (Chance: 10%)
Armor +5
Energy +4

Same skin as collector air staffs.

Thanks for your opinion!
