Sirius Dice unveils giant Themberchaud d20 for Dungeons & Dragons fans

Sirius Dice has put Themberchaud inside a 55mm D20, and the point is as much display as dice rolling. The oversized Dungeons & Dragons accessory is built as a crystal-clear resin piece with a pre-painted Themberchaud figure suspended inside, turning one roll into a tabletop showstopper.

The die is aimed squarely at collectors, Dungeon Masters, and fans who want a more dramatic way to call for a critical roll. At $81, it sits well above a standard consumable dice set and reads more like a premium fan object than a practical table staple. Sirius Dice is presenting it as a special-edition accessory, which matches the scale and the presentation.

Themberchaud gives the product its pull. The dragon has become one of the more recognizable modern creatures in the Dungeons & Dragons brand ecosystem, and Sirius Dice is leaning hard into that familiarity. A giant d20 with a dragon trapped inside is the kind of item that looks as good in a cabinet or on a desk as it does beside a character sheet, especially for players who already collect ornate dice as part of the hobby.

That merchandising strategy also helps explain why the release feels tailored for social sharing and retail display. The clear resin body lets the sculpted dragon stay visible from almost any angle, while the 55mm format makes the object immediately different from the dice most players actually bring to a session. It is the sort of release that turns a familiar gaming tool into a conversation piece, with the D20 itself doing the spotlight work.

The die is headed to retail on July 14, 2026, giving collectors a clear window to decide whether it belongs in a play bag, on a shelf, or in the completist pile. For D&D fans who value a striking piece of brand lore as much as a usable roll, Sirius Dice has made Themberchaud the kind of giant die that can sit at the center of the table even before the first initiative check is called.
