Blade of Pestilence

You throw a small blade of dark green liquid, which can appear as a dagger, dart, arrow, or any other small, bladed object. You make a spell attack, throwing it at a creature. On a hit, a creature takes 1d6 Acid damage and 1d6 Poison damage. 

The spell creates more than one blade when you reach higher levels: two blades at 5th level, three blades at 11th level, and four blades at 17th level. You can direct the blades at the same target or at different ones. Make a separate attack roll for each blade.
