concentration, 1 minute/mana
As an action, an object you touch becomes invisible for the duration. The spell ends if the object is used to make an attack or if you drop the object. If the object is used to make an attack, it is made with advantage.
On a hit, add 1d4 damage to the attack’s damage roll.
On a critical hit, add twice as much damage.
On a miss by 4 or less, add half as much damage.
