Toggle a modifier. The math handles itself.

  • Toggle Bless, Divine Favor, Crimson Rite — bonus dice animate and land in the Game Log, injected into the matching attack, damage, save, or check.
  • Crits are detected and doubled automatically, and modifiers only fire on the roll types they actually apply to.
  • Missing something? Build your own modifier in the custom builder, or turn any spell into one in two clicks.

Summon, track, and roll for your companions.

  • The Steel Defender and Drake Companion scale with your class level — HP, AC, attacks, and saves update live as you level up.
  • Clickable attack, damage, and save rolls, posted straight to the table's shared Game Log under the companion's own name.
  • Add any D&D Beyond monster you're entitled to — owned books, free rules, homebrew — or build one from scratch.

Questions people actually ask.

I've installed it — where is it?

Open any D&D Beyond character sheet. That's it — Rollwarden lives on the sheet itself, not in a browser popup, so there's nothing to click in your toolbar to "start" it. Load a character and the panels are there: a docked sidebar down one side by default, with a ⚙ button up by D&D Beyond's own header for settings.

The one thing that catches people out: it has to be an individual character sheet, not the My Characters list you land on first. Rollwarden deliberately stays out of the way on the list page — there are no dice there to work with — so click into a character and it appears. First time through, it'll offer a short tour.

Can I run Rollwarden alongside Beyond20?

You can, but expect conflicts. Both extensions hook into D&D Beyond's own roll flow to inject bonus dice and automate rolls, so running them together on the same character sheet can cause rolls to double up, apply the wrong modifiers, or behave inconsistently. If you're seeing rolls behave strangely, the first thing to try is disabling one of the two extensions on D&D Beyond. Rollwarden will show a one-time notice if it detects Beyond20 is also active. Neither extension is doing anything wrong — they simply weren't designed to share the same dice pipeline. If you run into a specific conflict, let us know on Discord or at support@rollwarden.app.

Is Rollwarden free?

Yes. Rollwarden is free to install and use. If you'd like to support development, you can buy the developer a coffee.

Does Rollwarden work on mobile?

No — Rollwarden is a desktop browser extension, so it needs a desktop browser with the extension installed. There's no mobile version, and mobile Chrome and Safari don't support extensions of this kind at all.

Does Rollwarden support Firefox?

Yes. Firefox is fully supported — it's the same extension, not a cut-down version. Modifier panels, dice interception, companions, Roll Log and stats, and pushing rolls to Discord and Roll20 all work exactly as they do on Chrome. It's a genuine port rather than a repackage: the mechanism Rollwarden uses to hook D&D Beyond's dice was re-validated on Firefox's engine before we'd claim support.

The build is with Mozilla awaiting add-on review — the last step is their approval, not more development. We'll put the install link here the moment it clears.

Which browsers does Rollwarden support?

Any desktop Chromium browser today, from the Chrome Web Store — Chrome, Edge, Brave, Vivaldi and Opera can all install from there.

Firefox is supported too, with its build awaiting Mozilla's review (see above). Edge has its own listing submitted as well, so Edge users get first-party updates instead of installing a Chrome extension — Edge works today either way.

Where do I report a bug or request a feature?

Join the Rollwarden Discord or email support@rollwarden.app — both are actively monitored.

Install Rollwarden from the Chrome Web Store and your next session's modifiers, crits, and companion rolls handle themselves.
