Celestial Blade

You evoke a sparking radiant sword 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 radiant sword. On a hit, the target takes 3d8 radiant damage.

The radiant blade sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

At Higher Levels. When you cast this spell using a spell slot of 4th- or 5th-level, the damage increases to 4d8. When you cast it using a 6th- or 7th-level spell slot, the damage increases to 5d8. When you cast it using a spell slot of 8th-level or higher, the damage increases to 6d8.
