As a bonus action, you may cast this spell after successfully landing a melee attack, such as with a simple or martial weapon, on a creature. Once cast, the spell will remember the attack you made against that creature before casting the spell and a translucent glowing blue mark will be visible where it was hit. If an attack is "stored" in the spell's memory. Casting the spell again will cause the creature with the mark to experience the exact same impact from the attack, causing to experience the same amount and type of damage, regardless of any changes to their armor or equipment.
For example, if you deal 10hp of bludgeoning damage to a creature by hitting with a mace, casting this spell with your bonus action will store the attack on the creature. If the spell is cast again, the creature will magically experience 10hp of bludgeoning damage in the exact same spot they got hit by the mace. The spell will work regardless of distance and the spell slot is only used for the initial activation of the spell. A caster can only have one instance of this spell active at a time.
