You cause a non-magical, non-masterwork weapon of a size that you can wield to appear in your hand. You may attack with this weapon as though proficient. If the weapon leaves your hand, it vanishes and the spell effect ends.

Each time you hit a foe with this weapon, the struck creature must make a Will save. On a success, the foe takes half damage from the weapon in that round (minimum 1 hit point). On successive hits, it must make new saves with a cumulative +1 bonus for each successful save previously made against your shadow weapon. If an attacked creature has SR, the resistance is checked the first time the shadow weapon strikes it. If the weapon is successfully resisted, it cannot deal damage to that creature. A weapon created using this spell can only deal damage to creatures with Intelligence scores and thus it doesn’t work on objects or mindless creatures.
