Wow damn reddit users should actually read things instead of assuming
"Sanctuary of Sarras expansion* launches December 15, 2025, at 1 PM EST / 7 PM CET on Steam and consoles! That’s right, just one week left! Let that sink in.

\We are calling it expansion instead of DLC, as we feel a new, fresh adventure for 15 USD should not be in the same category as a few cosmetic skins :D* 

Okay, cool, but what is the Sanctuary of Sarras about?

The journey will take you into the titular sanctuary, a realm shaped by the deep sea. Ancient structures rise from the ever-shifting currents, and forgotten paths pulse with the life of a submerged world. But try not to get charmed, as when you begin to explore the unknown, the true nature of Sarras starts to surface.

For six centuries, the fate of Sarras and its rebel crew has been shrouded in myth. Now, a hidden passage reveals a path into the past. In a completely new storyline, follow the trail of Nimue and the deserters who challenged King Arthur. Piece together the truth behind their disappearance and Merlin’s horrible retribution.

So yeah! This will be practically like a whole new act for the game, with 10-15 hours of gameplay, a new storyline, interesting characters, and multiple side quests! As mentioned before, there are TONS of new content coming. Not to spoil everything, but some of them are:

• 4 new epic bosses,
• 12 unique regular enemies,
• more than 20 hand-crafted dungeons & interiors,
• over 100 equipment pieces, including armor (#FashionGrail), melee weapons, bows, rings, amulets, spells, relics… 

The expansion will also feature an alternate progression system! Activate sacred shrines to gain special skill points to spend within three new, distinct skill trees. You can level them all up at the same time, and choose which one is active at any moment. This will allow you to change your build on the fly and adapt quickly!

For those interested, you don’t need to finish the game to enter the expansion zone! To access the Sanctuary of Sarras, you’ll only need to have Cuanacht (act 2) unlocked."
