Random Roll +/-1

Looking for a way to essentially roll a two-sided die where the results are either 1 or -1. Rolling (1d2-1) gets me halfway there, but I don't know how to exclude specific die results(in this case, 0). The goal is to have a randomized positive/negative multiplier for fluctuations in shop prices.

You could make a Roll Table that have only the two options, "1" and "-1", and call it for example, multiplier . Then you just make rolls with: 1t[multiplier] <a href="https://wiki.roll20.net/Roll_Table" rel="nofollow">https://wiki.roll20.net/Roll_Table</a>

This will also work [[2*(1d2-1)-1]]

Both are not as intuitive/one-click as I would have hoped, but they are both definitely workarounds that I can work into my random gens in a pinch. Thanks guys. Going one step further, is there a way to utilitize the rollable tables to generate a "shop inventory list" that will generate a semi-random amount of pre-gen items with prices and variable availability and output it as a table in-game? I could swear I saw someone do it once, but went our separate ways before I could ask how they did it.

While not exactly -1/+1, there are the Fate/Fudge dice built-in to Roll20 that are -1/0/+1 (<a href="https://wiki.roll20.net/Dice_Reference#FATE_Dice" rel="nofollow">https://wiki.roll20.net/Dice_Reference#FATE_Dice</a>).

Random inventory/pricing list sounds like a job for the recursive tables script . It supports expanding inline rolls within table items, which can include calls to other tables .&nbsp; Mediocre said: Going one step further, is there a way to utilitize the rollable tables to generate a "shop inventory list" that will generate a semi-random amount of pre-gen items with prices and variable availability and output it as a table in-game?
