Blooming Blade

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 is wreathed in blossoming vines until the start of your next turn. The target takes 1d8 acid damage the first time they miss with an attack roll while these vines are present.

This spell's damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 acid damage to the target on a hit, and the damage the target takes for missing with an attack roll increases to 2d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and at 17th level (3d8 and 4d8).
