Using this technique, one is able to set a trap that reacts strongly to high Chakra signatures. Upon completion of this technique, the user chooses a single 5-ft. square to host the "land mine." Once a creature with a Chakra Pool greater than 5 enters the chosen space, the explosion will be set off. All creatures within a 15-ft. radius centered on the chosen space suffer 50 points of fire damage from the explosion, which can be halved with a successful Reflex save. The explosion will set fire to flammable material and damage unattended objects.
