Brawler's Arena

Right. Maybe this was not a fitting moment for it though.
Where do you draw the line between "a player knows" and "this seems highly unlikely to be possible"? I guess if it were to be impossible to make the bookcase topple I'd have to add "you look at the bookcase and it seems impossible to topple it", so they can still change their action at that time.
That quote was from the 'signature weapon' move on the character sheet :). You are completely right, though.
Noted! :)
I wouldn't ever want to make any of my party members feel useless. If they do happen to lose their weapon or spellbook, I'd give them either a chance to get it back quickly or an alternative that they can use for a short while. I do however like the narrative of losing your most prized possession (for a while). Forcing them into creative new ideas that allow them to discover they are not defined by their weapon.
If that makes sense :)

This is very insightful, by the way. Thank you for taking the time to explain everything in detail!

Very useful, thanks! :)

That's actually a cool idea. I might steal that in the future ;)
Right. I'll be careful not to add negatives to successful rolls (unless this is discussed beforehand). Thanks for letting me know.

No problem. Depending on what happens next, I was thinking of having the goblin jump into a hole in the wall or a narrow crack behind furniture. Whether it gets that far, we don't know yet. So it might be relevant soon.

I would draw it forth from a conversation. :)
If they attempt something that does not seem feasible in the fiction then you chat about it.
It is is impossible, they have to try a different tack.
If it is possible but unlikely, then you roll for it.
If it is not hard, then it just happens.

The rolling decided in this case. But don't let them roll for things that are not possible. Get everyone on the same page BEFORE the dice come out, so there is not confusion about what is possible.
Or, it might be hard to use it as a weapon, even if it is not hard to topple it, especially with Bend Bars Lift Gates making the toppling possible where for others it might not be ('narrative permission'). In this case I might chat with the player and negotiate outcomes before they roll (always before, the player should not be surprised by what happens as a result of a roll, it should always be "of course that happens"). If they don't like the potential outcomes of a move, then they need to pick another move or do something else.

PbP can make us rush these things. Find a balance and accept that it is slow, especially at first while we all learn what the others things reality is.

"PLAYER: I leap across the chasm, do I need to roll Defy Danger DEX?"
"GM: Um.. the chasm is 60" across. It would be almost impossible for you to make it across, but you could, maybe, reach that ledge 20" below you on the other side. It will hurt unless you roll really well. Do you want to try?"
"PLAYER: Oh. I thought it was 16 feet, no I will, instead... push this enemy into the chasm. Defy Danger STR? Not my best stat, but it should be glorious!"
There is a lot going on, and the GM does not have the player's character sheets in front of them (though, it is not a bad idea for them to also have a copy of each sheet, for many reasons). Players need to speak up when their sheet contradicts the GM. "I'm immune to fear, because of my Quest Vow" or something.
Making the move a bit meaningless if you take the sting out of it. Let the consequence stand, unless you find you messed up.
It's m' job?
By the same logic: Don't let the consequences on a 7-9 negate the fact that they succeeded at what they were doing. It can be hard to come up with costs that don't. Practice.
On a miss, do that. The ranger is not as attached to their spear (or whatever it was, I have not looked at that part of the sheet) and can presumably make another one, even if it is crude and has some downsides.

I chose to waste ammo on this goblin to get the hit.
Is this the one that is already hurt?

Doh! Missed out one of my dice. Adding it here.
A 2 or better will make this a 10+ and save me the ammo.

Gotcha. Talk about it rather than drawing my own conclusions.
Definitely not easy, I've noticed in games. I always have the sheets nearby to check the moves when a player wants to use one. Or I just ask "what does your move say exactly?". Often the moves are quite vague though, but we come to an agreement.
Hmm, I'd say it depends a lot on the situation and how hard of a move seems necessary. Sometimes you just wanna give them a scare, rather than a crippling debility. No?
Still, I appreciate the effort and time :)
Yes, I try my hardest to not let that happen.
Just what I had in mind ;)

If you want Boy to retrieve the body and/or the weapon, you can have that happen.

I think that about ends the combat scene. The one goblin on John's sword can be swiftly dealt with if he so desires. Should we end things here?

If this is the end of this mock combat, I would like to set up another mock situation in another PbtA, this time with me as the GM and you guys, just 2 PCs. You guys ok with it?

Definitely, happy to help!

By all means.
We can always come back to this one later if we want.

Maybe we find that we don't have time to rest up and are assaulted by a new foe while unready and in a more desperate situation (one characer down a weapon (though within reach), one with dead weight skewered on their weapon, some with lowered HP).
