You focus the light of the moon into the form of any melee weapon you are already proficient with. Despite the name moonblade, the moonbeams can be focused into the shape of a bludgeoning weapon as well as a bladed one. The weapon, which can be wielded only by you, has the same threat range and critical multipliers as a real weapon of its form. It has no special modifiers to hit or damage, instead using your base attack bonus and any appropriate ability modifiers you possess. The weapon is considered magical for the purpose of overcoming damage reduction.

Moonblade can only be successfully cast outdoors, with the moon at least 3/4 full and no more than 50% cloud cover. Should cloud cover increase to more than 50% before the end of the spell’s duration, the weapon will vanish. Similarly, if you move indoors before the end of the spell’s duration, the weapon will vanish.
