Illusionist wand

How about creating an off-hand wand, that has the ability to create 2 illusions of the wielder. Each illusion would have 1/3 of the hit points of the user. The attacker could only inflict 1/3 damage to the player until the 2 illusions were destroyed. Give it a time limit or until the other 2 illusions are destroyed then full damage to the player takes place. Give the usage a cool down period. I think it would help players survive these 2 potion magic attacks that seem to do massive damage in a very short period of time. What do you think?
