A major D&D adventure is heading to Larian’s RPG via a wildly ambitious mod — the Mad Wizard Dungeon (Mad Mage’s Domain). The team asks for patience as the Waterdeep epic takes its first big steps.

You could call Baldur’s Gate 3 endless. Not because of Larian’s masterwork of branching choices and consequences this time. Not even because of the freedom afforded by 12 classes and 46 subclasses, plus a mountain of skills inside and outside combat. The game’s boundlessness also shows in its mod pipeline: the creation and editing tools are deep enough to enable truly outsized projects. Exhibit A: Mad Mage’s Domain, a fan effort targeting one of Dungeons & Dragons’ most iconic campaigns.

Dungeon Masters who love running tables in Waterdeep — and BG3 players who’ve adventured across Gale’s homeland — will likely recognize what’s coming. A group of fans is moving to adapt The Mad Mage’s Dungeon, the famed campaign that carries heroes from level 5 to 20 into the yawning depths beneath the Yawning Portal. The idea is to expand BG3 with a full dive into that legendary well and everything lurking below.

This won’t be easy: those who descend must brave “a labyrinthine dungeon that everyone but the hardiest adventurers avoids,” the “domain of a Mad Wizard who has stocked his lair with monsters, traps, and mysteries.” Over the years, the campaign has earned a near-mythic reputation, and bringing it to BG3 is as bold as it sounds. Lead developer Andromeda told FRVR the vision is already taking shape with help from roughly 400 volunteers.

A faithful adaptation—with smart liberties

Players have been pushing the official tools hard. While standout mods already exist, Andromeda spent months mastering the editor before committing. Now, she tells FRVR she’s ready to build Mad Mage’s Domain, and the community support looks robust. Many modders signed on with the goal of echoing BG3’s signature “decision, consequence, reaction” loop inside the adaptation.

“We plan to adapt the entire Mad Wizard’s Dungeon campaign to BG3, including all 23 dungeon levels and Skullport,” Andromeda said. “With 10 companion characters, over 500 named NPCs, and an expanded level range from 1 to 20 (the base game tops at 12), there’s a lot of work ahead — but with 400+ passionate volunteers, we’re ready.” She also wants to tackle a known weakness of the original: “It’s long and light on narrative scaffolding.” The BG3 dialogue system and act-based structure, she argues, let them enrich the throughline, deepen side characters, and let players experience the campaign in a fresh, story-forward way.

Building a giant mod is its own boss fight

Make no mistake: this is one of the most ambitious BG3 mods in development. Even at this early stage, the biggest hurdles haven’t been tool bugs so much as organization. “As a free, volunteer-driven project, finding robust, no-cost project management has been tough,” Andromeda noted. “We’ve rolled out custom systems and workarounds, and the team’s commitment keeps us moving.”

Accordingly, there’s no demo window yet. The scope suggests a multi-year runway, even as the community cheers the prospect of playing Waterdeep’s marquee crawl inside BG3’s D&D-based mechanics. Critics online caution that scale can bite back, but the prevailing sentiment is simple: with ambitions like these, patience is part of the adventure.

Bottom line: expect a faithful dive into the Mad Mage’s depths, framed with stronger narrative bones and tuned to BG3’s language — without losing that classic, old-school dungeon-crawl flavor.
