Disrupt the Aura

Anyone whose elements are out of balance will feel the effects, and this spell creates this condition deliberately by aggravating the Fire present in the target's body. While the spell is in effect, the target cannot be healed by magical means. Magical spells, items, or Techniques that attempt to restore Wounds to the target automatically fail. (Mundane wound treatment with the Medicine skill will still be effective.) The target may realize something is physically wrong with him but cannot find out what is happening without the help of a shugenja - casting Sense (Fire) will show the presence of many excited Fire spirits within the target.
