Call lightning

When a call lightning spell is cast, there must be a storm of some sort in the area--a rain shower, clouds and wind, hot and cloudy conditions, or even a tornado. The caster is then able to call down bolts of lightning. The caster need not call a bolt of lightning immediately--other actions, even spellcasting, can be performed; however, the caster must remain stationary and concentrate each time a bolt is called.

The bolt of lightning flashes down in a vertical stroke at whatever distance the spellcaster decides, up to 360 yards away. Any creature within a 10-foot radius of the path or the point where the lightning strikes is affected.

Because it requires a storm overhead, this spell can only be used outdoors. It does not function under ground or under water.

Note: This spell originally appeared in this form in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
