Barrelmancy

Three cylindrical wooden barrels full of explosive powder, each 5 feet in diameter and 5 feet tall, appear in unoccupied spaces that you can see within range and last for the duration.

The barrels are magically disguised as benign. A creature can attempt an Intelligence (Investigation) or a Wisdom (Perception) check against your spell save DC. On a success, the true nature of these barrels is revealed to that creature.

The barrels are objects that can be damaged and thus destroyed. Each barrel has AC 15 and 10 hit points. Reducing a barrel to 0 hit points destroys it and its contents, leaving no trace behind.

If a barrel is subject to fire damage, regardless of whether it is reduced to 0 hit points, the barrel violently explodes. Each creature in a 10-foot radius sphere centered on the barrel must make a Dexterity saving throw. A target takes 2d6 fire damage on a failed save, or half as much damage on a successful one. The fire spreads around corners and 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 3rd level or higher, you create one additional barrel for each slot level above 2nd.
