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.

Common Mistakes

Common Mistake
Forgetting it's a line originating from you, not a point - you choose the direction
Common Mistake
Not accounting for the 5-foot width when counting affected creatures
Common Mistake
Thinking you can bend the line - it must be perfectly straight

DM Tips

DM Tip
Generally less useful than fireball due to the line shape, but better in corridors
DM Tip
Can hit more creatures than fireball if they're lined up properly
