Axolotl

Axolotl is a Caster Type, Self Healing Magic.

Overview
This magic can be used to recover from any injury. Whether it be internal, or external, scratches or dismemberment, the user can always recover from it. This magic also activates automatically, so the user has no control over if they heal or not.

Weaknesses
Although this magic can effectively heal any damage to the body, it can not regenerate if the body has successfully been killed. It also drains one's magical energy, as they heal, so they won't heal after they've reached the absolute zero of their magical energy. It also takes longer to heal based on the more serious the damage was. The magic also can't be used to recover from disease, or poison.

Trivia
An axolotl, also known as the Mexican salamander, is an amphibious creature known for its regenerative properties.
