Burning Haze

When this spell is cast, an aura of heat appears around the caster. Any creature that ends it's turn 5ft from the caster must make a Constitution saving throw. The creature takes 2d4 fire damage on a failed save, or half as much on a successful one.
Due to the heat distorting the air around the caster, the caster has +1 AC vs ranged attacks.

At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot above 1st.
