To properly use this technique, the user must touch his hand to a swamp created by a Yomi Numa technique from his own Chakra Signature. The swamp's duration is reduced to 1 round/level, but it deals 1d6 points of acid damage to all creature trapped in it.
Creatures standing on it or sharing the user's Chakra Signature are unaffected, and Tadayou can still be used to normally stand on the swamp without penalty, but suffer 1 point of acid damage each round nonetheless, unless proper, protective footwear is worn.
