For a number of minutes equal to your level * 10, and once per day, you can inhabit the mind, eyes, and ears of an animal that is willing, or that fails your spell DC wisdom saving throw. You control, can see through, hear through the animals' body, and still retain your INT score, and can understand everything you normally would. This effect ends by will, when the time ends, or if the animal is killed. While warging, your original body is entirely helpless and senseless- you cannot hear or see, but you can speak. If the animal is killed the warging creature takes 1d8 psychic damage per level.
