Lightning Bolt - Artificer

Artificer's Lightning
These are little marble-like objects that are tied to their owner. When thrown, they act like regular marbles, but when the owner says, "Lightning Bolt." The marbles act as if they had used the call lightning spell.

These were orignally made as a joke object or party favor, but it was found by artificers that kobolds are stupid and easily captivated by shiny objects. They are also heavily susceptible to lightning bolts.
