Hi all! My players are about to face down one of my most sinister creations yet and they're very excited. After visiting an ancient settlement built over a chasm, at the bottom of which is a deep bubbling tar pit, they find themselves on the receiving end of a powerful Deathlock's magic when he reanimated from the depths of the pit the skeleton of a long dead Adult Green Dragon! This is no Dracolich. Merely the bones of the powerful beast.

The creature emerging from the pit is covered in sticky tar! Forgoing a breath weapon the dragon can vomit tar in a 40" cone causing some fire damage and restraining the targets who fail their save. In addition hitting the creature with a weapon causes it to possibly become stuck! Tar pools out from the creature in a 20" aura making the area around it difficult terrain.

Pretty neat if I do say so myself! My girlfriend has suggested that maybe somehow the PC's can become engulfed in the monster's body, but I'm not sure how that will work. Or possibly a successful attack has the chance to grapple the target! My PC's are only level 6 so I wonder if that would be too much...

As for the meat of this. It needs a cool bonus action, reaction, and something neat to do on round 1, 2, and 3.

I've already figured out what I want to happen on round 2. The creature flaps its useless wings sending tar splattering everywhere. The players make a save or a glob of tar hits them in the face, blinding them for a round.

I still need something for the first and third round though. I like Matt's suggestion that the first round villain action should mainly be about positioning. I want to challenge them, not kill them.

When the creature dies it will explode with an eruption of tar in a 20" aoe dealing some fire damage. That's all I have for it so far. Any suggestions?
