Celebrating GM’s Day!

We’re celebrating GMs everywhere with some incredible discounts, tools, and more!

Since 2003, GM’s Day has been a day of celebration for the incredible creatives behind the screen at your table whether it’s in-person or online. The official day for GM’s Day is March 4th, but at Roll20, we celebrate this amazing holiday for two weeks!

We have plenty of discounts across all our sites from Roll20 to DriveThruRPG to Demiplane and while we would love to highlight all of them, here are a few favorite titles as well as tools, to either celebrate your GM or celebrate yourself as the forever GM!

D&D Waterdeep: Dungeon of the Mad Mage

20% off on Roll20

Who is the “Mad Mage”? None other than the powerful wizard Halaster Blackcloak. He created the Undermountain: a vast, multi-level dungeon complex filled with traps, monsters, and mysteries!

Roll20 offers tools and features specifically designed to support the exploration, combat, and storytelling elements of the iconic dungeon crawl. It’s easy to manage tokens representing characters, monsters, and NPCs within the dungeon, and DMs have the freedom to set up encounters in advance, move tokens around the map during gameplay, and streamline combat encounters and other interactions. Additionally, integrated character sheets for D&D support character creation, stat tracking, and automated rolling of dice for attacks, saving throws, and other checks.

Plunge into the Undermountain’s depths with 26 adventuring maps ready for exploration with pre-placed tokens and full Dynamic Lighting support, including doors and windows (Subscribe to access Dynamic Lighting!)

Remastered Edition

Since we originally released Waterdeep: Dungeon of the Mad Mage, we’ve also released a bunch of new Roll20 features! This product is now updated with the following:

Doors and Windows, interactable by players on the token layer!
Page Folders, better organizing the maps by chapter!
Token Actions on all NPCs, allowing GMs to quickly roll without needing to open their sheets!
Higher Quality Art, like tokens and art handouts, using new “pop-out” style tokens and nameless handouts to avoid spoilers!

Improved Cross-Linking in adventure text handouts, getting you to the right paragraphs right when you need them!
Corrected Dynamic Lighting, fixing some edge cases and making moving through maps a breeze!
Errata from the last few years included in the text where appropriate!

Dungeon of the Mad Mage Companion

40% off on DMsGuild

Halaster’s Game: The Companion rewrites Halaster Blackcloak into a deranged game show host whose program, Dungeon of the Mad Mage, is broadcast across the Multiverse! It’s this insidious game that the adventurers find themselves trapped in! (Note: the Companion is still a hefty resource for DMs that don’t adopt this element.)

DM Notes: Quick notes for every chapter, summarizing the level and listing the highlights.

Variants Galore: Where something could be polished, or where it ought to have been abolished, the Companion provides you variants you can use—be it a rewritten narrative, new foes, or alternate encounters.

Magic Items: To spare yourself the time of leafing through the Dungeon Master’s Guide, the magic items found in these chapters have been included.

Monster Statblocks: You guessed it: the monsters used throughout these levels have been compiled and their statblocks reproduced for your convenience.

Dungeon of the Mad Mage Companion: The Complete Edition is your one-stop guide for running and fleshing out Dungeon of the Mad Mage!

(Just A Few) GM Tools

While Roll20 has a massive span of GM Tools available, we wanted to highlight some of our favorites that we recently released to help make your next campaign simple to set up and easy to use.

Free Maps & Tokens

We have a few selected free Roll20 Maps and Tokens for quick claims to get your table set! Whether you’re prepping your first session or hoping to quickly find quality art for your campaign on a budget, we’ve curated a collection of free art and tokens to get you started quickly. From heroes and monsters to maps and decor, our gracious marketplace partners have teamed up to offer a great selection of starter art.

Free Quickstarts

Get into your game fast with free quickstarts on Roll20! These quickstarts are set up to help you learn a game and walk you through the mechanics. They include ready-to-play adventures, too!

Some of our favorites:

Map Pins

One of the most asked for features, Map Pins, has arrived for everyone with different levels of customization. Map Pins allow GMs to pin information and link handouts to specific map locations, creating a richer, more interactive storytelling experience. Pins can be visible or hidden, allowing for dramatic reveals during play like unveiling a quest or NPC backstory, shedding light on a found location, or springing a trap on an unsuspecting party.

Maps Pins is officially out of beta, meaning it’s ready to go for your next campaign setup. Read more about it in our Help Center here!

Foreground Layer

Foreground Layer came out of Beta in April and we are loving the community’s response and showing us how they use it! The highly requested Foreground Layer provides GMs way more control. You can incorporate rooftops, tree cover, weather effects, reactive traps, and countless other creative uses, with fine tuned controls for how elements fade in-and-out and interact with lighting.

Dungeon Scrawl

Dungeon Scrawl helps connect your ideas to the table with as little friction as possible, and today, we’re making it even easier to manage images, customize the look and feel of your maps, and share your creations with others!
