This sealing technique scribes a seal on the target's body to contain chakra. When the technique is completed, the subject may pour up to 5 points of chakra inside each seal. The chakra poured into a seal gives the subject a -1 penalty to its chakra pool per point. When undone the penalty from the seal is removed and the subject immediately recovers the chakra. The chakra inside the seal cannot be sensed, but is immediately obvious to creatures who can See Chakra or See Through Chakra, even through thick clothing and armor, and grants creatures with the abilities a +4 bonus to Spot checks to spot the subject.

Up to three seals can be undone as a free action, each requiring a Ninjutsu check (DC 15+amount of chakra in the seal). Releasing more than 3 seals is a move-equivalent action. A failed check means the seal is not released, and attempting to release the seals may provoke an attack of opportunity.
When undone, the chakra contained in the seal returns to the subject's body.

Mastery
The first, third and fifth step of mastery increases the amount of chakra contained by the seals by 1 (up to .

Expendable Components: Enough ink to scribe a small seal. Scribing the seals requires a Craft (calligraphy) check (DC 24) to be made, not necessarily by the user, and takes 1 minute. If the check was failed, the sealing process will fail without the user noticing until the end.
