Blazing Blitz

You lash out at your target, making a melee attack as mild embers, temporarily, coat your weapon until after you've made the attack. The target must make a charisma saving throw. Should they pass the save, they take half damage. On a fail, they take the full damage.

The embers do not damage the weapon used in the spell, even if it's non-magical. You can add your spellcasting ability modifier to the hit roll instead of strength or dexterity.
