Drifting Mines

Beads of dark orange energy launches from your palm. You create four 5ft squares next to each other, they must be connected. If a enemy enters one of these 4 squares, the caster may trigger the area to explode, dealing 2d4 fire damage. This is a free action.

If the caster decides to end concentration, all remaining areas will explode at the same time, dealing damage to anyone inside.

The fire damages objects in the area and ignites flammable objects that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 2d4 for each slot level above 2nd.
