Using this technique, the user is able to slowly encase the subject in earth, rock and mud. If the target fails its saving throw, it is caught in the technique's first step. To increase the strength of the prison by 1 step, the user must spend an attack action concentrating on the prison while within range, which can be done once per round. Concentrating on the technique provokes an attack of opportunity which can be used to disrupt his concentration. Once formed, the prison will remain active until it is either destroyed or the technique ends. There are all of three steps to this technique.

• First Step: The target's feet are caught in the prison and it cannot move, turn around or use any technique requiring mobility. The subject suffers a -2 penalty to Defense and Reflex saves. He can break out of the prison by succeeding a Break check (DC 27) or destroying the prison with a held weapon, unarmed attack or have another creature attack it. At this stage of the technique, the prison has 20 hit points.
  
  
• Second Step: At this point, the subject loses his Dexterity bonus to defense and suffers a -4 penalty to attack rolls and Defense. He cannot use techniques requiring mobility or any semblance of leg movements. At this stage of the technique, the prison has 35 hit points.
  
  
• Third Step: The subject is completely covered by the prison and is immobilized. He cannot use any technique requiring hand seals, half seals, mobility or any semblance of movements. The subject can breathe in the prison for 5 rounds before he starts suffocating, and may also hold his breath. The subject can break out of the prison with a Break check (DC 30) or another creature can break him out, but he cannot attack the prison himself. At this stage of the technique, the prison has 50 hit points.
  

Material Focus: A Large (at least 100 pounds) source of earth, sand, mud or rock nearby to form the prison.
