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 druid is then able to call down bolts of lightning from sky to ground. Each bolt will cause damage equal to 2 eight-sided dice (2d8) plus 1 like die (d8) for each level of experience of the druid casting the spell. Thus, a 4th level druid calls down a six-die (6d8) bolt. 

The bolt of lightning flashes down in a perpendicular stroke at whatever distance the spell caster decides, up to the 36" radial distance maximum. Any creature within a 10 foot radius of the path or the point where the lightning strikes will take full damage, unless a saving throw vs. Spell is made, in which case only one-half damage is taken. 

The druid is able to call one bolt of lightning every 10 melee rounds (1 turn), to a maximum number of turns equal to the level of experience he or she has attained, i.e. 1 bolt per turn for each level of experience. 

Note. This spell is normally usable outdoors only. However, if a djinn or an air elemental is on hand to form a whirlwind, the druid is able to summon half-strength lightning strokes therefrom.
