Quick, semi-related question -- is it standard in the rules that you mark experience if you roll a miss?  I think it's not in 2.3, but I'm not sure how it works, or worked previously.

Also, what if it was spend XP to change the result to 7-9?  That eschews the whole "10+ is the boring outcome" part of the above.

Along comes DW and they say make it dangerous and don't be afraid to kill characters, so I decide to go along with that. Actually, I am fine with that since that is supposed to be the tone of the game. Now what you are talking about here is to take me back to my old ways and fudge things enough that the players struggle but make killing more rare.

It's hard to fudge when players roll all the dice -- it might work for you if you rewrote the Last Breath move?  Or just include that rolling a miss on Last Breath will get an extra-potent bargain from Death in order to return to life.  There's some discussion of this in the text if I believe.

Just a thought if you wanted to keep things less lethal!  Otherwise, resurrection is a bit of a motif if people are fine playing a different character for awhile.
