Tracking OneDnD Exhaustion

I can't figure out an effective way to track Exhaustion on the "DnD 5e by Roll20" sheets using the OneDnD method of subtracting it from every d20 roll.

I tried changing Core Dice Roll to use "1d20-@{exhaustion_level}" which seemed fine at first, until I realized that adding any calculations beyond a basic dice causes it to not add any additional modifiers to any d20 rolls. Like if I have +6 Stealth and 4 Exhaustion, it should be rolling 1d20+6-4. Instead it just rolls 1d20-4.

The other solution I've found is to just create a separate Global Modifier for every type of roll, but that's incredibly tedious to manage.

Does anyone know a good way to handle this?

Global Modifier is the best method, you only need to make three of them (saves, attacks, and skills). Set it up as a query that asks the exhaustion level. 

From my memory, the Core Dice Roll is used with a couple other calculations (such as Advantage/Disadvantage), so you can't modify the roll at the end.  You should be able to use this:

-@{exhaustion_level}[Exhaustion]+1d20

However, one problem with using the @{exhaustion_level} attribute is that it only goes up to a maximum of 6.  Instead, you could use an 'other resource'. If you do, I would suggest setting it up to be the first 'other resource' on each player's character's sheet:

Then you'd reference it in the Core Dice Roll like so:

-@{repeating_resource_$0_resource_left}[Exhaustion]+1d20

Ah, you're right about it working when I put the -Exhaustion first on the Core Dice Roll.

I'm not running into an issue with it capping out at 6 though. It seems to work fine at higher levels.

-Edit- Nope, okay. It works, but the character sheet starts throwing out complaints about it being over 6. So you were right about that being the limit I think. I did have to use one of the resource boxes in the end.

I have a newer version here that works with the exhaustion level on the sheet,
rather than a token marker. It can be found here.

I've got a script somewhere that reads the number on a token marker to track exhaustion. and modifies the base roll. I dropped it when I realized it had two issues:

1) it couldn't account for multiple tokens assigned to one character (mooks)

2) You had to make sure the token marker was correct whenever you pulled out a fresh token.

Here's the code if anyone wants to fiddle with it.

on('ready', () => {
    const exhaustionMarker = "Exhaustion::5992372";
    const exhaustionRx = new RegExp(`(?<=${exhaustionMarker}@)\\d`);
    function setExhaustion(obj) {
        const tokenStatus = obj.get("statusmarkers");
        let rollString = {
            core_die: "1d20"
        };
        if (tokenStatus.includes("Exhaustion")) {
            let exhaustionLevel = exhaustionRx.exec(tokenStatus);
            if (exhaustionLevel === null) {
                exhaustionLevel = 0;
            } else {
                rollString = {
                    core_die: "-" + exhaustionLevel + "[Exhaustion]+1d20"
                };
            }
        }
        if (obj.get("represents")) {
            setAttrs(obj.get(("represents")), rollString);
        }
    }
  const onChangeGraphic = function(obj,prev) {
    if(obj.get('statusmarkers') !== prev.statusmarkers) {
      setExhaustion(obj);
    }
  };
  on("change:graphic:statusmarkers", onChangeGraphic);
  if('undefined' !== typeof TokenMod && TokenMod.ObserveTokenChange){
    TokenMod.ObserveTokenChange(onChangeGraphic);
  }
});

I don’t see a Pro subscriber tag next to Zack’s name, so I’m assuming he doesn’t have access to scripts  :) Still might be helpful for anyone who does!

True, I hadn't checked. But maybe it will have some value to someone. :)
