Cosmic Vessel: a free mod expands Baldurs Gate three

Published on June 10, 2026 | Translated from Spanish

The Baldur’s Gate 3 community celebrates the arrival of Cosmic Vessel, a fan-made mod that adds an original character, a new class, spells, and weapons. As free content, players can extend their experience without paying extra, filling the void left by the original studio by not releasing official expansions.

How modders overcome the game engine's limitations 🛠️

The modder team behind Cosmic Vessel has worked with Larian Studios' engine to integrate custom animations and visual effects for the new spells. They also modified data tables to balance the additional class with existing ones, avoiding progression breaks. The process involved adjusting dialogue and quest scripts so the new character fits without conflicts with the main storyline, all using free editing tools.

The DLC that never was, but fans made for themselves 🎭

While Larian executives counted bills on their vacations, a group of fans with coffee and patience has birthed what the company didn't want to release: new and free content. Cosmic Vessel shows that if there's no official expansion, you can always ask a modder to make one in their spare time. Of course, don't expect them to fix your corrupted save; that's another mod entirely.
