The next time you hit a creature with a melee weapon attack during this spell's duration, your weapon is sheathed in pulsating fire, and the attack deals an extra 2d6 fire damage to the target.
Additionally, creatures hostile to you that are adjacent to the target must succeed on a Dexterity saving throw or take 1d4 fire damage.
When you cast this spell using a spell slot of 2nd level or higher, the fire damage increases by 1d6 for the primary target and 1d4 for adjacent foes for every slot level above 1st.
