By default, the challenge roll is 3-in-6, which represents rolling 3 or less on a d6 roll.
A player may elect to increase their character’s chance of success by bidding boons, which are fictional factors that makes a task easier, and increase the X-in-6 chance (up to 6-in-6, which is an auto success). Fictional factors that make a task harder are called banes, which decrease the X-in-6 chance (down to 0-in-6, which is an automatic failure). Boons and banes cancel out 1-for-1, which means a given roll should only be made with one or the other.
If you give me a mechanic where I the player can manipulate the roll I will go for it. Let me manipulate the roll, play with the dice and let us bargain. I agree it is not for everyone, but I frakkin love it!
One thing that could be added to the bargain is the Devil’s Bargain from Blades in the Dark. By accepting an extra negative outcome, that will always come true, I get a boon. Think it could be a good addition.
