Book Barrage

Book Barrage is a spell, which can be used at 95 Magic. It can hit up to 912, and will appear as two or three books flying at the player. It requires five air runes, one law rune, two cosmic runes, five earth runes and two nature runes. It needs to recharge 10 seconds to use again. Finishing the Alphans' Quest can reduce the amount of runes and recharge time.
