One player describes their character planting a bomb in a car, intending to kill all who are in the car when the bomb goes off.
Two named characters get in the car. Boom. Conflict begins.

Do we do two separate conflicts: Bomber vs Bombee #1 then Bomber vs. Bombee #2.

Or, does the Bomber only roll once (either as Challenger, or one Re-Roll as Answerer) and both Bombee's roll against the same total, in the order of highest to lowest?

Assuming Bomber rolls higher than both others and thus has established themselves as the Challenger and they both Answering this challenge.

Rustin, thanks for the PM reminder.

Here's a summary:

Dice, action & consequences summary
- To begin the round, everybody rolls dice for their forms according to their characters’ actions, and including dice for particular strengths as appropriate.
- Everybody gets a turn, in order from high roll to low.
- The high roll stands; everybody else picks up their dice.
- On your turn, reroll your dice, unless your turn was first.
- On your turn, make a challenge. Say who has to answer it.
- Everybody who has to answer, gets to answer, in turn order.
- On your answer, reroll your dice and compare.
- If you have to answer before your turn, you lose your move. You get a move only if it comes to your turn and no one’s challenged you.
- Once the last person’s had her turn, the round ends.
- After the first round, write names on the owe list.
- In the third round, all winning and losing is absolute. It never goes past the third round.

Vincent,

Thanks, I think that helps me understand.

From the wiki it sort of reads that for each challenge you could only have a single answerer.  I was mistaken. We can name multiple characters as answerers, and they all roll against that same total.

I would assume multiple challenges would have to stay inside the scope of the Endeavor?
I can’t make Sally fall in love with my character by chopping Joe’s foot off.

A reactive challenger will still be able to do dice damage to someone, even though the active character hasn’t had a chance to specifically challenge anyone yet. We assume something happened, caused by the active character, within the narrative because we have entered a conflict.

The situation I’m imagining is the car bomb, the bomb still went off even though one of the characters in the car won initiative.
