The user attaches the Spirit Seal Card to the target. A second Spirit Seal Card is attached onto the user, or some else's body (typically the arm). Upon performing the hand seals, a connection is made between the two Seal Cards. The bearer of the second Seal Card can perform any of their jutsu, and in place of their own chakra, use the target's. The effects of Spirit Seal wear off when the target runs out of chakra, or the flow of chakra between the two Seal Cards is interrupted.
Before attaching the seal, the user can embed his/her chakra into the Spirit Seal Card. The user can then throw the card and control its speed and direction. The Seal Card can be homed onto the target, instead of attaching it directly.
