Good..
( Fūin Fuda ) – Sealing Tag
Rank: B
Type: Supplementary
Range: Short-Mid
Chakra cost: 20
Damage points: N/A
Description: Once one of these tags is placed on an object, either by hand or by being attached to a kunai and thrown, a substantial seal slowly forms over the target. This prevents the target from moving or being summoned.
Note: The seal takes a while to form, so any opponent can rip it off negating its effects entirely, if he does so within five seconds.
Note: This technique only works against summons, or bodies resurrected via Edo Tensei.
This is self explanatory. Though when in the act you must be quick and agile. Carefully inserting enough chakra into the seal and not too much or too little. Understood?
( Chakra Haisui Fūin no Jutsu ) – Chakra Suppression Seal Technique
Rank: B
Type: Supplementary
Range: Short
Chakra cost: 20
Damage points: N/A
Description: The user places this seal on the forehead of a Jinchuuriki influenced by the powers of a Bijuu, to forcibly cause the Bijuu's powers to recede. The Jinchuuriki becomes exhausted after this happens.
Note: This can only restrict Jinchuuriki in their Incomplete form, not when they completely transform into the Bijuu.
Self explanatory.. Understood? Its pretty much the seal causing the chakra to recede, by what specific means, we do not know. But it could probably be severing the connection between the host and the beast..
