Flame Swathe (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a tiny golden bell)|
When cast, a small burst of fire appears at a point you choose within range that swirls around whilst priming itself for detonation. A 10-foot sphere blast radius around the point is visually indicated with a harmless ephemeral aura. At the beginning of your next turn, the fire momentarily vanishes before blossoming into a 10-foot radius explosion of flames, inflicting fire damage equal to 4d12 + your spellcasting modifier to every creature caught in the blast that fails a Dexterity saving throw, or half as much damage on a successful one. Both the aura and the fire spread around corners. The fire 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 5th level or higher, the damage increases by 1d12. When you use a spell slot of 7th level or higher, the damage instead increases by 2d12.
