Chrome Extension · D&D Beyond

Your character sheet, automated.

Rollwarden overlays modifier automation, a companion tracker, and roll helpers directly onto D&D Beyond — so bonus dice, crits, and summoned creatures resolve themselves in the Game Log.

Active Modifiers

Toggle a modifier. The math handles itself.

Rollwarden hooks D&D Beyond's own dice worker — bonus dice animate and land in the Game Log like any other roll.

⚔️

Live dice injection

Bless, Divine Favor, Spirit Shroud, Crimson Rite, Haste, Sacred Weapon and more — bonus dice get injected into the matching attack, damage, save, or check automatically.

💥

Crit-aware

Critical hits double a modifier's bonus dice, detected from a context-menu crit or a natural 20 on the preceding attack — no manual doubling.

🎯

Skill & save restrictions

Modifiers like Warder's Intuition only fire on the roll types they actually apply to, like Investigation checks.

🛡️

Forced advantage

Vecna's Link, Large Form, Grappled, and Haste automatically force advantage on the saves and checks they affect.

⚡

Live AC & Speed

Haste updates AC (+2) and Speed (×2) directly on the sheet the moment it's toggled on.

🛠️

Custom modifier builder

Build your own attack, save, or ability-check modifiers with dice or flat bonuses — and hide any built-in modifier you don't use.

Companion Panel

Summon, track, and roll for your companion — in the shared Game Log.

  • Full stat blocks and HP tracking for Otherworldly Steed, Tyrannosaurus Rex, Giant Ape, and Mammoth.
  • Clickable saving throws and attack / damage / save-effect rolls, posted straight to the table's shared Game Log.
  • Spell-summoned creatures scale automatically with the spell level they were cast at.
  • Give your companion a custom name that shows up on the stat block and in every roll it makes.
  • Companions can carry their own modifiers — Bless, Crusader's Mantle, Aura of Devotion, Haste.

Roll Breakdown & Reminders

Know exactly what just happened — without digging through the log.

  • Draggable popups break down every roll's dice, modifiers, and damage types as it lands.
  • A celebratory banner fires on crits, so the table knows immediately.
  • Smaller reminders surface weapon mastery effects, Haste's extra action, and secondary-target damage for spells like Green Flame Blade and Booming Blade.
  • Everything auto-dismisses, and any popup can be turned off in settings.

The Rollwarden button

A draggable launcher sits on your sheet and opens a settings modal where you can hide any panel or popup you don't want — Active Modifiers, Companion, Roll Breakdown, or Reminders.

Bring your D&D Beyond sheet to life.

Load Rollwarden as an unpacked Chrome extension and your next session's modifiers, crits, and companion rolls handle themselves.
