[Usage : ] cast minor healing [<on target>]
[Components : ] None
[Effect : ] Minor Healing is surely a staple in any Cleric's list of
spells. When casting this spell the target defaults to the
caster. Minor Healing heals the target a small amount of
hit points at a small cost. A given subject can only
benefit from one healing effect in a certain span of time,
so be careful not to use Minor Healing when a more powerful
effect is called for.
