To properly use this technique, the user must be in direct contact with the earth or rock hewill make his shelter from. He creates a sturdy, simple hut made of earth and stone with a level floor that is relatively clean and perfectly sanitary. In all respect, the earth haven might resemble a normal house made from stone. It has no windows and only one entrance large enough to let a Medium-sized or smaller creature though without problem. The entrance can be oriented anywhere to the user's chosing, and a cloth can easily be installed to block sight and weak winds.
The shelter has no heating or cooling source beyond natural insulation qualities, but does retain its heat fairly well. Therefore, sources of high heat, such as a fire, are likely to incomodate the shelter's occupants. The shelter is as strong as a normal stone building, regardless of its composition, and resists flames and fire as if it were stone. It is impervious to normal projectiles, but not those of overly large size, such as siege weapons.
The shelter is completely bare of any furniture. It will last until dispelled, even if the user goes to sleep. The duration can be increased by 1 hour at the cost of an additional 1 point of Chakra when performing the technique, up to 10 hours.
