Smoke briefly surrounds you, and you teleport up to 10 feet to an unoccupied space you can see. Fire or smoke (your choice) bursts out from the space you left.
If fire bursts from the space, each creature within 5 feet of that space must make a Dexterity saving throw, taking 1d6 fire damage on a failed save, or half as much damage on a successful one.
If smoke bursts from that space, a 5-foot-radius sphere of smoke appears centered on that space. The smoke’s area is heavily obscured and lasts until the start of your next turn.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st. When you cast this spell using a spell slot of 2nd level or higher, the spell’s range and the radius of the smoke each increase by 5 feet for every two slot levels above 1st.
