Tainted Grail: The Fall of Avalon - Sanctuary of Sarras is an action RPG expansion that adds a substantial underwater region to the base game's dark fantasy world. Players explore a submerged realm filled with ancient ruins, new characters, and a storyline tied to Nimue and rebels who defied King Arthur centuries earlier. The expansion delivers around 15 hours of content focused on exploration, combat, and narrative choices in a singleplayer experience available on Xbox Series X|S.
Gameplay
Combat blends melee weapons, ranged attacks, and magic spells in real-time encounters. Players manage stamina during fights, dodge incoming strikes, and switch between loadouts to adapt to different threats. The base systems carry over into the expansion, where underwater enemies scale dynamically to the player's level to maintain tension throughout the new area.
Progression receives a notable update with three distinct skill trees exclusive to the Sanctuary of Sarras. Activating scattered sacred shrines grants points to invest in these trees, and players can swap the active tree at any time to adjust their build on the fly. This encourages experimentation with different playstyles during the roughly 15-hour campaign. Over 20 new dungeons and interiors await exploration, alongside more than 100 pieces of equipment including armor sets, weapons, rings, amulets, relics, and spells.
Side content includes interactions with new characters whose stories players can influence through decisions. The underwater setting features shifting currents and ancient structures that shape navigation and discovery. Level scaling ensures encounters remain challenging regardless of prior progress in the main game.
Game Modes
The experience remains strictly singleplayer, centered on the main storyline and optional side quests within the new region. No separate multiplayer or co-op modes exist. Players follow a linear entry point into the Sanctuary during Act 2 of the base campaign, then gain freedom to explore the submerged zone before the story concludes and locks the area permanently.
Quest design emphasizes narrative depth over repetitive tasks. A new main questline reveals details about the rebel fleet's fate and Merlin's retribution, while side activities involve helping or ignoring new inhabitants. Fast travel becomes available after specific progress, and exploration rewards thorough players with hidden items and encounters.
Story and Setting
The expansion expands the Arthurian lore with a self-contained tale of deserters who sought escape from Avalon's wars. Six centuries of myth surround the sunken kingdom of Sarras, now accessible through a hidden passage. Players piece together events involving Nimue and the consequences of defiance against the king.
Ancient structures rise from the ocean floor in an environment untouched by the Wyrdness and Red Death that plague the surface world. The atmosphere shifts from the perpetual autumn of Avalon to a submerged domain where forgotten paths and naval creatures define the landscape.
Is It Worth Playing?
Players who enjoy first-person open-world action RPGs with strong narrative focus and build customization will find value in the expansion's additions. The new skill trees promote experimentation, and the story enriches the larger mythos without requiring a full replay of the base game. Reception for the Sanctuary of Sarras has been positive, with praise for the lore expansion, side quests, and the fresh progression layer that encourages trying different approaches.
The base game holds a Very Positive rating on major platforms, reflecting sustained player interest through patches and additional free content releases. Those seeking a compact 15-hour addition with new bosses, adversaries, and equipment will appreciate the focused scope. The singleplayer format suits those who prefer solo exploration and choice-driven storytelling over competitive or cooperative elements.
