Ninja Art: Ripple Curse Mark

When Doujinn performs the hand seals,he takes his pointer and middle fingers and stabs in the desired spot. The victim gets a Rinnegan like mark on the spot they were hit and once Doujinn says the words "Ripple Control" and Sharingan like tomoe appear on top of mark and it starts to burn. He then can make his chakra flow in the victim and infuse his DNA, boosting the victim's powers.
