I cut the description short as I said you go first >____>
------------------------------
Xanxus looking at his opponent with a boring look as he didnt seem like much, he thought of this as a easy kill. He starts to get serious and as earth is his second specialized element, he quickly performs two hand seals making the ground below his opponent change into a fairly large size of mud. He then performs a single seal and slammed his hands on the ground with know time to waste, creating a giant portal, similar to a boar (shape wise) type lid of earth falling down on the opponent, crushing him.
(Doton: Yomi Numa) - Earth Style: Swamp of the Underworld
Rank: A
Type: Supplementary
Range: Short/Long
Chakra Cost: 30
Damage Points: N/A
Description: The user will first perform Boar → Tiger and then by changing the surface of an object beneath an enemy into mud and creating a non flammable 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 the swamp. 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 which is extremely effective against a great number of enemies or when having to face gigantic creatures.
(Doton: Otoshibuta) – Earth Release: Dropping Lid
Rank: B
Type: Offensive
Range: Short-Long
Chakra cost: 20
Damage points: 40
Description: After doing the Snake handseal and slamming his hands on the ground, he user creates a portal above the target, high in the sky from which a giant, boar-shaped, earthen lid drops and falls on the target, trapping it underneath. The lid can be hollow or solid, depending on if the user wants to deal damage to the enemy or not. Because of its size, to safely used, the lid has to be created at least mid range from the user otherwise he will also be caught inside. The biggest lid can dwarf a boss summon like Nagato's Dog or Gamabunta.
