Stillwater Cave is an early-to-midgame dungeon located near the southern edge of Liurnia of the Lakes in Elden Ring. Exploring this cavernous area provides players with valuable items, unique crafting materials, and a challenging boss battle against a Cleanrot Knight. Navigating its treacherous interior requires preparation against environmental hazards like status effects and surprise ambushes.

Finding the Location of Stillwater Cave

To locate Stillwater Cave, head to the far southern shore of the Liurnia wetlands, directly beneath the towering cliffs bordering Limgrave. The cave entrance sits tucked away along the cliffside wall surrounded by shallow, murky waters. Players approaching from the Lake-Facing Cliffs can carefully descend the mountain path to reach the lake floor near the cavern entryway.

Keep an eye out for aggressive wildlife and toxic pools guarding the exterior of the location. Bringing a torch or lantern is highly recommended, as the interior completely lacks natural light sources. Setting up at a nearby Site of Grace before venturing inside ensures you will not lose your progress upon an unexpected defeat.

Preparing for Environmental Hazards Inside

The primary obstacle within Stillwater Cave is the dangerous poison swamp covering much of the floor. Standing in these toxic pools rapidly fills your poison meter, eventually causing continuous health loss over time. Bringing Neutralizing Boluses or using poison-curing incantations will make your exploration far smoother and safer.

In addition to environmental traps, you will encounter multiple Servant of Rot enemies hiding along the murky paths. These aggressive foes can attack from range with poisonous projectiles and quickly overwhelm unprepared adventurers. Maintaining a cautious pace allows you to lure individual targets away from larger groups effectively.

Navigating Through the Cavernous Paths

As you progress deeper into the cave, search every corner for useful crafting resources like Poisonbloom and Cave Moss. Small ledges and hidden alcoves often contain treasure chests holding specialized gear and consumable items. Clearing out ambient enemies before looting guarantees you can collect items without taking unnecessary damage.

Drop down through the lower tunnels carefully to avoid fall damage or landing directly into enemy ambushes. The winding path eventually leads toward a fog wall blocking the final chamber. Ensure your health and FP reserves are fully replenished before stepping through the threshold into the boss arena.

Defeating the Boss and Claiming Rewards

The boss waiting inside Stillwater Cave is a formidable Cleanrot Knight equipped with a thrusting sword and spear. This agile opponent uses rapid holy attacks and dangerous grab maneuvers that inflict heavy physical damage. Using spirit ashes or dodging sideways during thrust attacks creates crucial openings to land heavy counter-strikes.

Defeating the Cleanrot Knight grants a generous amount of Runes alongside the Winged Sword Insignia talisman. This valuable accessory increases your attack power with successive melee hits, making it an excellent reward for fast-attacking combat builds. Completing this dungeon thoroughly prepares players for the greater challenges awaiting them across Liurnia.
