Storm King's Thunder is a Dungeons & Dragons adventure campaign for 5th Edition, published by Wizards of the Coast, and is officially available on the Roll20 Marketplace.



Giants have emerged from their strongholds to threaten civilization as never before. Hill giants are stealing all the grain and livestock they can while stone giants have been scouring settlements that have been around forever. Fire giants are press-ganging the smallfolk into the desert, while frost giant longships have been pillaging along the Sword Coast. Even the elusive cloud giants have been witnessed, their wondrous floating cities appearing above Waterdeep and Baldur’s Gate. Where is the storm giant King Hekaton, who is tasked with keeping order among the giants?

The humans, dwarves, elves, and other small folk of the Sword Coast will be crushed underfoot from the onslaught of these giant foes. The only chance at survival is for the small folk to work together to investigate this invasion and harness the power of rune magic, the giants’ weapon against their ancient enemy the dragons. The only way the people of Faerun can restore order is to use the giants’ own power against them. This adventure for characters level 1 - 11+.

Included in the Roll20 Module edition of Storm King’s Thunder:

Over 250 hours of campaign preparation completed for Roll20 users
Over 200 statted Tokens featuring original artwork from Dungeons & Dragons.
Over 40 battle-ready Maps. The module is advanced feature-enabled, with Dynamic Lighting on 23 Maps.
The entire book's content is presented in Handout form with cross-linking for efficiency

Accessing Your Module

The Game Creation Page

When you Create a New Game, on the right hand side of the creation page is a section called Optional: Choose a Module. Listed here will be various modules available on the Marketplace. Storm King's Thunder (a thumbnail of the image you see at the top of this page) will be listed here too. After purchasing this module, a big white checkmark icon will appear over the thumbnail when you hover your mouse over the Storm King's Thunder option. This showcases that you have this module unlocked (Content that has not been purchased yet will reveal a shopping cart icon and will link you to its Marketplace listing). Click on the thumbnail to select it. This will assign this module as the template for your new game as well as automatically choose the Official Roll20 OGL Character Sheet as well as the 5th Edition SRD Compendium to be applied to it. Name the game whatever you wish and click the blue ✔ I'm ready, Create Game! button to create the your new game. After a minute or two (this is a very large module to load), Roll20's application will open with your new game and Storm King's Thunder's content will be available to you as well as access to the 5th Edition character sheet and Compendium.

Adding Pre-Existing PCs to the Game

Storm King's Thunder is designed with either player characters beginning at level 1 or adapting existing characters from a previous Wizards of the Coast adventure (Lost Mine of Phandelver, Hoard of the Dragon Queen, Prince of Apocalypse, and Out of the Abyss). If your gaming group is coming from one of these adventures or some other adventure in another Roll20 game, there are two ways to pull their character sheets from another game to this one.

Character Vault

The Character Vault is a place to import one's Character Journal, Character Sheet, and linked Token for safe keeping. Any player can import a character into the Character Vault regardless of their subscription level. Usually, exporting characters into a game requires the game creator to have a Pro subscription; however, if your game uses a purchased Marketplace module, the Character Vault's export capacity unlocks, allowing players to export their saved characters to that game.

To save your character to the Vault, go to the Character Vault page and click on the blue + Import Existing Character button. This will bring you to the Import Page where there is a drop down list of Games that you've created or are currently a player in. Select the game you need and then a second drop menu down appears that lists any Available Characters: you have access to (has control of). Select the character you want and click on the blue Import Character button.

This will bring you back to the main Character Vault page and your selected character will now be listed in the Vault, as well as the date it was added, and the option to export it to a game or delete it from the Vault. Clicking on the blue Export to Game » button beside your desired character will reveal another drop-down menu of available games you can export your character to. Only Pro-level or Module-unlocked games will be available on this list. Choose the desire game and click on Export to Game button to add it to the game. This will add the character journal, sheet, and linked token to that game.

Transmogrifier (Pro)

Pro Subscribers have access to the Transmogrifier tool. This will allow them to copy individual items or batches of items from one game into their current one. You're not limited to Character Journals either. Most features in the Roll20 app are transferable via the Transmogrifier.

The Adventure Book's Content

Purchasing the Storm King's Thunder module does not include a PDF of the adventure book, but the entire book's contents has been converted into Handout form on the Journal Tab. The Handouts are organized by book chapter and the bestiary of Monsters/NPCs, Magical Items, and player handouts have their own separate Handout folder. All Handouts utilize cross-linking for easy jumping between adventure chapters, map guides, monsters/NPCs, magical items, player handouts, etc.

Battle Map Scaling

Map scale varies across the collection of battle maps within Storm King's Thunder. To make movement and token placement ideal, we have adjusted the grid on some of the maps so that tokens are easier to select and manipulate. Listed below are all the maps in this module and what scale they are currently set at. We also include instructions on how change the grid if you want to follow a closely accurate strategic method of combat. With the latter, we recommend moving the tokens with the arrow keys instead of the mouse due to the small token size. With the adjusted maps, we tried to keep the tokens size relative, so a large creature is larger than a medium creature and so on.

Non-Gridded Maps

These maps do not have a grid, but are sized so that if you use the Measurement Tool, it will count the correct distance length.

Non-Gridded Maps in Storm King's Thunder

  • Bryn Shander
  • Goldenfields
  • Triboar
  • The North
  • Everlund
  • Tuern & Purple Rock
  • Gundarlun & Ruathym

50 Foot Maps

Each grid square on the art is 50' with no Roll20 grid subdivisions. Medium/Small tokens are set to .5 to .5 units (technically 25' by 25') here. The grid is disabled so there's no snapping.

If you wish to set it for scale accuracy, enable the Grid and set the Grid Size in Page Settings to 0.1 units. Token Sizing is as follows: Medium/Small/Tiny (0.1 unit by 0.1 unit), Large (0.2 unit by 0.2 unit), Huge (0.3 unit by 0.3 unit), gargantuan (0.4 unit by 0.4 unit)

50 Foot Maps in Storm King's Thunder

  • Flint Rock
  • Grandfather Tree
  • Great Worm Cavern
  • Morgur's Mound
  • One Stone
  • Raven Rock

  • Stone Stand

20 Foot Maps

Each grid square on the art is 20' with a single subdivision in the Roll20 grid (Grid Size set to 0.5). Each Roll20 grid square is 10'. Medium/Small tokens are set to 1 unit (technically 10' by 10') here.

If you wish to set it for scale accuracy, set the Grid Size in Page Settings to 0.25 units. Token size is as follows: Medium/Small/Tiny (0.25 unit by 0.25 unit), Large (0.5 unit by 0.5 unit), Huge (0.75 unit by 0.75 unit), gargantuan (1 unit by 1 unit)

Optimization Recommendations

Storm King's Thunder is one of the largest if not the largest module we offer on the Roll20 Marketplace in regards to scale (giant dungeons offer a lot of ground to cover) and amount of content. A GM may find that such a large game may run sluggishly on their's or their player's browser, or find the content very overwhelming at first. There's a couple of optimizing measures you can take to help manage the bulk of this module.

Archiving Pages/Journals

The Page Toolbar and the Journal Tab both have an archival system. This allows you to pack up Pages and Character/Handouts into an archive folder for safe keeping, so you have less items to scroll through to get what you need. Anything placed in the Archive can always be retrieved later.

The Page Archive

The Page Archive
The Archive Button on the Page Settings Window

To archive a Page, you need to open the Page Settings of the Page in question and scroll to the bottom of the window where there is a button labeled Archive Page. Clicking on this button will close the Page Settings window and also move that Page from its spot on the Page Toolbar and into the Page Archive. As soon as one or more pages are added to the Page Archive, a new Page appears with an Inbox Icon (left image) as the very last item on the right side of the Page Toolbar titled "[Number of Pages] Archived". This is the Page Archive.

Clicking on the Page Archive will open a window that displays all presently Archived Pages. You can restore Pages from the Archive by clicking on the Restore button beside the Page Title in this window. The original position of the Page before you archived it is retained. If there are no other Pages in the Page Archive, its icon is hidden from the Page Toolbar.

The Journal Archive

The Journal Tab Archive
Archiving Journals.png

To archive a Journal item, Handout or Character, right click on it to bring up an options menu. One of the available options is Archive Item. Clicking on this option will move the Journal item into the Journal Archive. As soon as one or more items are moved to the Journal Archive, it appears at the bottom of the Journal Tab featuring an Inbox Icon (right image).

Clicking on the Journal Archive will open a window that displays all presently Archived Journal items. You can restore Handouts and Characters from the Archive by clicking on the Restore button beside the Handout/Character Title/Name in this window. The original location of the Journal Item before you archived it is retained. If there are no other items in the Journal Archive, its icon and listing is hidden from the Journal tab.

Adjusting Dynamic Lighting Settings

For Plus and Pro Subscribers, Dynamic Lighting has been set up for many of the available Battle Maps in by Storm King's Thunder. If you or your players are having difficulty with the Dynamic Lighting (lag), we recommend a couple of options to try:

Enable 'Only Update on Drop' on the Page Settings: This will adjust the lighting/line-of-sight only after a user picks up a token and then drops it down to a new location on the Tabletop.
Turn Off 'Has Sight' on NPC tokens: All tokens on the Tabletop have Has Sight enabled. If it's just the GM struggling with lag, it's possible that the sight radius of every single token on the Tabletop being calculated is slowing down their Dynamic Lighting processing. If they double click on a token to bring up its Token Settings, they can disable the Has Sight option from the Advanced Settings tab of that window.

Breaking Up the Campaign

The number of statted Character Journals in a game is what affects game performance. For users who are running the module over a WiFi connection, it may be necessary to break the module up into two or three smaller games so there's less content to load each time you launch the app.

Step 1: Create a new game with the Storm King's Thunder module.
Step 2: Add your players character journal/sheets to the game and anything else important to to your game.
Step 3: Go the Game Details page for this game and click on the Settings button to drop down a menu. Select Copy Game.
Step 4: On the Game Creation Page, make certain that the options for Players and Player Settings, Pages, Decks, and Journal are checked off. Any other options are up to the GM's discretion whether they're needed or not. ALSO, select the Character Sheet you were using as the option defaults to None upon a game copy. If you weren't using a custom or community-created sheet for Storm King's Thunder, select the Dungeons & Dragons 5th Edition SRD by Roll20 character sheet.
Step 5: Repeat Step 4 as needed.
Step 6: Begin deleting content from your games. Pages are deleted from the Page Settings and Journal items are deleted by right clicking on them to bring up their Options menu. These are permanent changes, but if you ever make a mistake, you can always create a new game with the Storm King's Thunder module to retrieve that content again.

Pro Subscribers can skip several of these steps with the Transmogrifier Tool. Instead of making multiple copies of the same game and making varying deletions, all they have to do is make a single game for the entire module first. Then they can create another game without the module to play from (make sure you assign the desired 5th Edition Character Sheet you want to use). From the blank game, they can pull in the module content from their Storm King's Thunder game via the Transmogrifier only when it's needed.
