[Spells help] recharge

Syntax: cast recharge 

Recharge gives the caster the ability to increase the amount of charges
remaining on a magical wand or staff.  There are several limitations to this
ability.  First, the spell contained by the wand or staff must be one known
to the caster who is attempting to recharge it.  Second, if the spell is not
known well, a fumbled attempt may cause the item to leak energy and lose an
extra charge instead.  Third, attempting to overcharge a staff will cause
it to explode into a burst of lightning.  The item to be charged must be in
the caster's inventory.
