A sword made of holy fire blazes to life in your hand. the size and shape of the blade conforms to your will, but it is never larger than a one-handed weapon sized for a Medium creature. If you let go of the blade, it disappers, but if you maintain concentration on the spell, you can evoke the blade again as a bonus action.
You can use your action to make a melee attack with the burning blade. On a hit, the target takes 2d6 fire and 2d6 + your spellcasting modifier radiant damage. On a critical hit, the target catches fire; until someone takes an action to douse the fire, the target takes 2d6 fire damage at the start of each of its turns.
The burning blade sheds bright light in a 10-foot-radius and dim light for an additional 10 feet.
Using a Higher-Level Spell Slot. Both fire and radiant damage increase by 1d6 for each two spell slots level above 4th.
