   The above spells are all healing spells which restores the health of the
target.  These spells are purely for use by the cleric class, and are really
powers granted by the gods.  Cure light is the lowest level, and least
powerful spell - heal is the most powerful, and can only be cast by high
level clerics.  Additionally, you must learn these spells in progression -
you must learn the simple healing spells before the complex ones.

Healing may be done while in combat, or even while fighting.
