Method of Chakra Reading

Chakra Shori no Waza (Method of Chakra Reading)
Ninjutsu (Requires Kaikken no In (t))
Rank: 3 (B-Class);
Range: Touch;
Effect: Reads a seal containing residual chakra;
Duration: Up to 12 rounds;
Saving Throws: None;
Chakra Cost: 6.

The user touches a kaikken no in or similar seal and is able to read the residual
chakra information stored in it. The user is able to determine the type of technique chakra (Chakra Control, Genjutsu, Ninjutsu or raw chakra, such as taijutsu techniques, bloodline effects, speed or strength ranks, etc.) in the order it was used, going backwards, and may attempt to identify the chakra signature of the creature who used the chakra with a Wisdom check (DC 20, no retry) if he is sufficiently familiar with it.

Each round spent reading the chakra goes back in the recorded history of the seal by 1 hour, and any read information is destroyed.
