Players contribute action & description towards an open ended outcome based on the cards they played on the challenge, but they must not resolve the challenge it if they did not play the final point on the card. Leave room for the Player or Narrator to write the final resolution.
There are some exceptions…
Occasionally the Narrator may reserve writing challenge outcomes to themselves in cases where particular information is to be delivered to further the game or other odd circumstances require it. This convention will not be over-used and will be clearly specified on the challenge card outcome..
Some challenges may have a different outcome for each Character, in this case each character writes their own outcome based on the strength of their own cards played. This should be apparent from the nature of the challenge.
