Draconic Flame Blade

You evoke a white-hot draconic fiery blade in your free hand. The blade is similar in size and shape to a longsword, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action.

You can use your action to make a melee spell attack with the draconic fiery blade. On a hit, the target takes 5d6 fire damage.

The draconic flaming blade sheds bright light in a 20-foot radius and dim light for an additional 15 feet.

Once hit, the enemy must succeed on a Constitution saving throw with a DC equal to 10 + your spellcasting abilities modifier, or be burned and take 1d6 damage every turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 3rd.
