Beaming Blade

You imbue one melee weapon you touch with arcane energy, causing it glow a vibrant hue of your choice (blue if you don't choose) for the duration.

Once per turn when you take the Attack Action and attack with the weapon used in the casting, you can make a ranged spell attack against a creature within 30 feet of you instead of a weapon attack, launching a beam of energy the color of the weapon's glow at the target. On a hit, the target takes Force damage equal to 1d8 + your spellcasting ability modifier.

Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 1.
