"light Switch"
<p>Crystal capable of casting spark at a specified location (aim: direction, distance)
Precise measurements must be taken from the location the stone is to be placed to where the spark should take place.
A stone may cast multiple sparks in multiple locations, but this increases the difficulty of the item creation.
 
crafting item:
an uncracked crystal about the size of a human thumb
magic parchment to write the spell and directions for the casting location on
Cast spell "Awaken Crystal" on the crystal
wrap the parchment around the crystal and cast the "Absorb Written Spell" spell</p>
