How to make a device to randomly choose one of three possibilities, with caveat that sometimes one of them is not available?

This looks like a job for a Rondel. Put the three attacks in consecutive sectors of a circle, and after the initial d3, put a marker (a coin, a d6, whatever) on the previously used move. When choosing ...

How do you handle random encounters if the GM isn't supposed to roll dice?

What you're describing is what I'd call, in traditional D&D, a random reaction roll, not a random encounter — so I'll address reactions and how to decide them in Dungeon World. The GM rules are ...

How can I generate multi-story random dungeons without having to do the entire random gen process by hand?

I'm unsure if this answers your question; as I'm not sure if you want the enemies, descriptions, and all that to be generated as well. Assuming not, I have a non-generated solution that may work.. ...

How do you handle random encounters if the GM isn't supposed to roll dice?

Well, I hope they're not going into a genuinely random building. Just barging into somebody's house isn't likely to get much in the way of a friendly reaction, but if the PCs say "oh, I want to ...

For the Conjure Animals spells, are the summoned fey spirits 'smart' enough to take a form that fits the summoning locale?

This is a matter of DM technique and the flow of play Currently I'm running Conjure Animals fairly restrictively. That's a DM choice, and you don't have to tie your own hands. But I don't think ...

How can I get an AnyDice conditional to convert a sequence to a boolean?

You're slightly wrong about what's wrong But it's slightly Anydice's fault. It doesn't have good debugging tools. The specific issue Anydice has here is that you're trying to compare a die to a value. ...

What's the closest I can get to simulating critical hits with a dice pool, without relying on the total sum?

If you want a fun way to do it and you're in person, you could have someone call a pair of the dice which have to add up to exactly 8 (e.g. 1+7, 2+6... 7+1) which is 4.86% according to anydice (though ...

How do you handle random encounters if the GM isn't supposed to roll dice?

Use a coin. Beyond the first roll, you're just rolling a d2 and picking one of the options that weren't used before. If you can 3D print, make a coin with one side "1", and the other side &...
