I asked this a few pages ago and never got a response. Assume for a moment the OP's scenario is as follows (it's my understanding of what happened):
- The lone paladin is carrying a badly injure NPC that cannot walk on their own.
- They come across an adult dragon
- The PC makes a diplomacy check, explaining that he is part of a group trying to save the world. If he fails, the dragon will die along with everyone else.
- The PC rolls and gets a very good result
- The dragon responds "Leave the injured man and you may go"
- The PC leaves the NPC and goes
Sound about right? You discuss it with the player after the game. They tell you:
"I gave it my best shot. I saw no way of surviving the encounter with the dragon. I believed any more discussion would lead to my death in addition to the death of the NPC. As much as I would have liked to save the NPC, I didn't see any alternative. My mission to save the world is more important."
What do you respond?
Because I know how I would respond. I screwed up. At the very least I should have given the player an insight check to know that the dragon's response was just an opening offer, not an ultimatum. At this point I'd discuss with the PC what to do next. He's not an oathbreaker, but it is a gray area one that certainly could haunt him even if he believed there was no better option. Maybe he needs to say a dozen Hail Titanias*. Seek counsel of another paladin or cleric. Have a dream/vision where he visits the Feywild and learns that at some point he must return the bones of the NPC to a sacred grove.
Because that's what we should be addressing. What's an appropriate response for a DM in this situation and why?
