One of my D&D players has a bad habit of metagaming and using his own knowledge of source material in ways that his character should clearly not be able to. I never really go out of my way to punish him for it, but I also have made it clear over the course of all of my games that monsters and their abilities are not always exactly what you will find in the Monster Manual or Bestiary.
So the party recently came up against a dragon, in a sort of roundabout way. Adult dragons in my world are basically just a step below gods, terrestrial beings whose power is still beyond those of any other terrestrial beings, so they’re not there to fight the dragon, they just want some important piece of information that’s in his lair (it ties back to our barbarian’s backstory).
So while they’re in the dragon’s lair, which is a giant two mile in diameter labyrinth, the warlock (played by the metagamer) ends up isolated from the rest of the party. The dragon wants to make a deal. He says that he will allow the party to proceed through his labyrinth, with no consequence or opposition, and get to their objective, if he will do just one favor for the dragon. That favor? Destroy an object (a dragon egg) that is exceptionally important to an NPC (the NPC had betrayed the dragon earlier specifically to protect this egg).
So, for backstory, here is what the players and their characters know about Dragons (and this specific dragon) in my setting.
*Dragons are extremely powerful.
*Dragons often have abilities that are derived from their concept and personality, while they have mechanics, are not found in the rulebook.
*This dragon is a tyrant, who binds living creatures into its service.
*This dragon uses bloodletting to bind people into service (i.e. spill your blood to seal the pact)
*The dragon has bound bigger creatures than any of them into its service.
So, the dragon offered this deal to the warlock. The warlock says he wants to bluff. He says yes. The dragon clarifies that the warlock agrees to his terms, emphasizing that he is not threatening him and will not kill him for refusing. The warlock says yes. He rolls bluff, but as soon as he has agreed to his terms the dragon cuts his cheek and says “The pact is sealed.”
The warlock’s player asked if it was a “Geas” spell, which forces its subject to perform a specific task.
I say that I have not looked at the Geas spell, because the effect is not a Geas.
The warlock asks if he can counterspell it. I tell him he can try. He says the DC to counterspell a Geas should be 15. I tell him to roll it. He gets like, a nine. It doesn’t matter, because it’s not a Geas, it’s a special ability. It cannot be counterspelled by either of the subjects because it only binds a deal that both characters agree to and, bluff or no, he agreed to the terms.
But he goes forward acting like it’s a Geas and behaving as though it’s a Geas. He tells the other players that his character cannot tell them what’s wrong. I tell him that nothing is stopping him. He says “It’s part of the text for Geas.” I say “Oh, okay.” It doesn’t matter, because it’s not a Geas, but I have now decided that there is a lot of value in letting him believe that there is.
The time comes for the warlock to deliver on his oath and he balks. He lets the other players stop him. He decides that he will just take the 5d10 damage that comes with violating a Geas spell and assumes that it will go away when he can no longer complete the quest (when the dragon egg hatches). I decide he will go ahead and take the damage, and then chooses to knock himself out instead of fulfilling his end of the deal. That was where our last session ended.
He has made all of these choices without ever asking to make an arcane roll or any other check to actually determine what effect he was under. He never asked what the consequences of breaking the deal would be. So, I have mechanics drawn out for what will happen, but since I have until Saturday to change things, I’m open to suggestions.
Extra Details:
*The dragon is lawful evil.
*Even though a dragon’s color isn’t as super important in my game, this dragon’s personality and powers are pretty close in line with the Green Dragon entry in the Monster Manual.
*If you want to know what is in store for them as I have it planned, watch the meteor segment from Stephen King’s Creepshow.
