Heals target for a great number of hitpoints. The amount of healing is not random on use and increases according to level and the magic level of the player using the rune.
Note:
Most frequently, a player uses this rune on himself, but it can also be used to rescue a fellow player or a Summoned Creatures from dying. Clerics or Sorcerers using this rune on themselves are guaranteed to completely heal because their magic power is a lot higher and their maximum hit points are much lower than knights or paladins of equal level.
