You touch a spot on any surface, creating a circle of runes with a radius of 5ft with the spot you touch at the center. The circle flares up, then disappears leaving no trace except for a faint magical imprint that can be discovered by the detect magic spell.
At the end of the spell's duration, the runes emit a flash of light and the circle detonates, causing a loud explosion that can be heard up to 300ft away. Creatures and objects within 5ft of the circle, including the surface it is on, take 2d8 bludgeoning damage and 2d8 fire damage. If the circle was inscribed on a nonmagical wooden surface the wood contained within the circle immediately shatters into burned splinters.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the amount of bludgeoning and fire damage increases by 1d8 for each slot level above 1st.
