Combustive Seal

Overview
A jutsu which allows the user to scribe a seal capable of holding fiery chakra, this allows a user to set up traps by storing their flames for later use. Once stored, this seal fades from the view of normal eyesight, detonating when a source of chakra other than the user comes nearby or if the user chooses to release the seal. This technique is akin to an Exploding Note.

Special
Release: While a seal is active, the user may pay half the Cp cost and .5 Ap to detonate the seal. Doing loses the normal Sneak Attack bonus, and instead the 'Chance to set off' the seal becomes a 'chance to be a sneak attack'. This may be used reflexively.

Charge: Upon initiation, the user may choose to seal an additional Fire Jutsu into the trap. However, this lowers it's chance of setting off by -4%. The user pays all costs normally, including the increased Ap.
