Rollwarden — Smarter Dice Rolling for D&D Beyond

Rollwarden adds a toggleable layer of buffs, automated bonuses, and a companion tracker directly on top of your D&D Beyond character sheet — so you stop doing dice-math in your head and start clicking buttons.

Active Modifiers Panel
A floating panel lists every buff and feature your character can use, split into Features & Traits and Spells columns. Click to toggle one on, and Rollwarden automatically injects its bonus dice or flat bonus into D&D Beyond's own roll the next time you click any of the site's native dice icons — no separate roller, no manual math. Includes ready-made support for common effects like Bless, Spirit Shroud, Crimson Rite, Bardic Inspiration, Green Flame Blade, Booming Blade, Sacred Weapon, Aura of Protection, Haste, and more — many of which auto-scale their dice with your character level.

Build Your Own Modifiers
Don't see what you need? A guided, step-by-step wizard walks you through creating your own custom modifier: name it, then pick what it affects — Saving Throws, Ability Checks, Attack Rolls, Damage Rolls, and/or character Stats (AC, Speed, ability scores) — all in one buff if needed, just like Bless affecting both attacks and saves. Bonuses can be a fixed number, a dice roll, or tied live to one of your ability modifiers (so a "+ Charisma to attack rolls" modifier always stays correct as your character changes). Mark modifiers as mutually exclusive (like Green Flame Blade vs. Booming Blade) so toggling one off the other automatically. Edit or delete any modifier later, including the built-in ones.

Roll Breakdown Popups
After an attack, save, damage, or ability check roll, a small popup shows exactly what happened — base roll, each bonus that fired and from where, critical hits, and the final total — so you always know why a number is what it is.

Companion Tracker
A second panel tracks a summoned companion creature (Otherworldly Steed, Tyrannosaurus Rex, Giant Ape, Mammoth) with its own full stat block, HP tracking, and dice rolling for attacks, saves, and abilities. Give your companion a custom name that shows up on its stat block and in the shared Game Log. Companion rolls post to your table's real, shared Game Log alongside everyone else's.

Character Info, Always in Sync
Rollwarden reads your character's class, race, level, spell save DC, and spellcasting/ability modifiers directly off the sheet — so scaling effects and ability-based bonuses update automatically as your character levels up or your stats change, with no manual re-entry.

Settings
A single settings panel shows your character's key stats at a glance and lets you hide any individual panel or popup you don't want — Active Modifiers, Companion tracker, Roll Breakdown popups, or smaller reminder popups (weapon mastery, Haste's extra action, etc.) — without losing any of your saved data.

Privacy-respecting by design
Everything Rollwarden does happens locally in your browser. It reads your own character sheet to do its math and writes nothing anywhere except your own device's local storage. No accounts, no servers, no tracking, no remote code.
