In our current DW game I am playing a bard with the alignment Neutral.
"When you avoid a conflict or diffuse a tense situation, mark XP."
I used Parley to try to get my party to lower their weapons in a tense situation. I rolled an 8. Another character, who had a bond with me, then interfered to negate my roll (8-2=6). Combat ensued. Do I mark XP?
On the one hand, I made a move to diffuse a tense situation and avoid a conflict. It would be consistent with rolling highlighted stats that my attempt is what matters, not the success of the move (e.g. if DEX is highlighted I still mark XP if I fail my Defy Danger roll).
On the other hand, in the fiction, I was not able to successfully diffuse the situation. A literal interpretation of the rules would dictate that I did not, in fact, diffuse the situation.
Which is more important, the intent of your actions or the outcome? I could see it going either way.
[edit] Furthermore, do I mark XP when I run away from a fight?
