Veerstein's Ember Sear

The inside of your hand becomes a flesh searing, red-hot source of heat. Make a melee spell attack against the target. You have advantage on the attack roll if the target is unaware of the intent. On a hit, the target takes 6d10 fire damage and is pushed 15 feet away from you. The caster takes half of the damage dealt, or half as much on a successful Constitution saving throw. A critical hit doubles the damage to both the target and caster. On a miss, the caster still takes half of the damage rolled, or half as much on a successful Constitution saving throw.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 2d10 for each slot above 1st.
