Blade of Wrath

You create a sword of pure white fire in your free hand. The blade is similar in size and shape to a longsword, and it lasts for the duration. The blade disappears if you let go of it, but you can call it forth again as a bonus action. You can use your action to make a melee spell attack with the blade. On a hit, the target takes 2d8 fire damage and 2d8 radiant damage. An aberration, fey, fiend, or undead creature damaged by the blade must succeed on a Wisdom saving throw or be frightened until the start of your next turn. The blade sheds bright light in a 20-foot radius and dim light for an additional 20 feet.
