Drunathi gel bomb

This slippery fluid carries a potent electrical charge that explodes when it is rapidly re-exposed to air. You can use an action to throw this flask up to 20 feet where it shatters on impact. Make a ranged weapon attack against a creature or object, treating the drunathi gel bomb as an improvised weapon. On a hit, the target takes 1d6 ongoing lightning damage. This damage persists for 1 minute. A creature can end all ongoing damage being dealt by drunathi gel bombs by using its action making a DC 17 Dexterity check to clean the fluid off itself, making the check with advantage if it drops prone.
