Acid Splash Strike

You brandish the weapon used in the spell’s casting, conjuring a bubble of acid to coat the weapon.  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 you may then splash the acid bubble onto a hostile creature adjacent to you. This second creature takes acid damage equal to your spellcasting ability modifier.

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 acid damage to the second creature increases to 1d8 + your spellcasting ability modifier. Both damage rolls increase by 1d8 at 11th level (2d8 and 2d8) and 17th level (3d8 and 3d8).
