Butterflies Waltz

You brandish the weapon used in the spell's casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack's normal effects, and shimmering butterflies of blue, pink, and violet light burst from the strike.

You can direct the butterflies toward a different creature you can see within 5 feet of either you or the original target. The second creature takes radiant damage equal to your spellcasting ability modifier.

The butterflies leave behind a brief trail of sparkling light before fading away.

At Higher Levels. Beginning at 5th level, the melee attack deals an extra 1d8 radiant damage to the target on a hit, and the radiant damage to the second creature increases to 1d8 + your spellcasting ability modifier.

Both damage rolls increase by 1d8 when you reach 11th level (2d8) and 17th level (3d8).
