As an action, a stroke of lightning blasts out from you in a direction you choose. The lightning ignites flammable objects in the area that aren’t being worn or carried. Each creature in a cone or line must make a Reflex saving throw.
On a failure, it takes 3d8 lightning damage and can’t take reactions until the end of its next turn.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
You can increase the damage by 1d8 for each additional mana expended.
Staggering Bolt. You can expend 1 additional mana so the damage is reduced to 2d8 and each creature who fails the saving throw is staggered until the end of its next turn.
