Talmon's Torch

You focus your pyromantic energy into your hands for sustained length, allowing for bouts of flames that are effective, even while in close range. While this spell is active, you may use your action to activate the flames from your hand. When you do so, you may force the first creature within a 30ft long, 5ft wide line in front of you to make a Dexterity Saving Throw, the line then stops after that creature. On failure, creatures within the line take 3d8 Fire damage, or half on a success. This spell deals double damage against nonmagical structures and objects.

When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
