Earth Release: Swamp of the Underworld

By changing the ground beneath an enemy (relative to them) into mud and creating a swamp, the user can sink his enemy into the mud. The adhesive, chakra-infused mud ensnares the enemy's body, making it almost impossible to recover one's strength and escape from there. The size and depth of the created swamp depends on the user's skill and the amount of chakra used, but if the user is an expert in this technique, it will always be possible to make a fair-sized swamp. When fighting a great number of enemies or having to face gigantic creatures, this is an extremely effective technique.
