Cobalt Staff

The Cobalt Staff is the second weapon you'll find.

It looks like a double axe, is not a melee weapon. Instead, it fires a volley of blue mana projectiles. Middle projectiles do more damage.

The alternate fire is acquired later and fires a large volley of blue mana projectiles, doing massive damages. It has a cooldown that prevents firing the alternative fire too quickly but does not prevent you using the primary fire.
