Lightning Bolt

A stroke of lightning forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a dexterity saving throw. A creature takes 8d6 lightning damage on a failed save, or half as much damage on a successful one. The lightning ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.

This spell releases a powerful stroke of electrical energy that deals 1d6 points of electricity damage per caster level to each creature within its area. A save vs. Spells for half damage is allowed. The bolt begins at the caster's fingertips and extends to the range given. The caster may choose to limit the range of the spell, but the minimum range is 60 feet. The lightning bolt passes through an area 5' wide, arcing and jumping, so that, while it is not actually 5' wide, for game purposes treat it as if it is so.

The lightning bolt sets fire to combustibles and damages objects in its path. It can melt metals with a low melting point, such as lead, gold, copper, silver, or bronze. If the damage caused to an interposing barrier shatters or breaks through it, the bolt may continue beyond the barrier if the spell’s range permits; otherwise, it may reflect from the barrier back toward the caster, or in a random direction at the GM's option. Creatures already affected by the lightning bolt do not take additional damage if struck by the reflection of the same bolt.
