How to Beat Starscourge Radahn in Elden Ring

Elden Ring has earned worldwide recognition for featuring some of gaming’s most formidable boss encounters. Among these legendary challenges stands Starscourge Radahn, a demigod warrior whose combat prowess has become legendary within the community. While technically classified as an optional encounter, recent developments confirm that defeating this colossal foe becomes essential for players seeking to experience the Shadow of the Erdtree expansion content. This guide provides comprehensive strategies to not only unlock but also conquer this monumental battle.

Starscourge Radahn occupies the southern peninsula of Caelid, specifically within Redmane Castle’s deepest reaches. Accessing this confrontation requires triggering the Radahn Festival event, which dramatically alters the castle’s layout and enemy placements. Once activated, warriors can utilize a mystical portal inside the fortress to transport directly to the combat arena where Radahn awaits.

Two distinct progression paths enable players to initiate the Radahn Festival in Elden Ring. The primary methods involve either advancing through Ranni the Witch’s extensive quest chain or acquiring and utilizing the Grand Lift of Dectus. Each approach offers unique advantages and fits different playstyles, though both ultimately lead to the same dramatic castle transformation.

When successfully triggered, the festival completely redesigns Redmane Castle’s interior, removing standard enemies and replacing them with festival attendees and merchants. The most crucial addition is the shimmering portal near the castle plaza that serves as the gateway to Radahn’s battlefield. This event-based alteration remains active until Radahn is defeated, after which the castle reverts to its normal state.

Ranni the Witch, offspring of Radagon and Rennala, ranks among Elden Ring’s most powerful demigods. Her initial appearance occurs at the Church of Elleh under the alias Renna, where she provides the Spirit Calling Bell to worthy Tarnished.

Initiating Ranni’s questline demands journeying to the Three Sisters area, accessible by traversing Caria Manor in Liurnia. Players must overcome Royal Knight Loretta to clear the path from Caria Manor to the Three Sisters towers.

Progressing through Ranni’s narrative involves multiple key stages: encountering Blaidd in Mistwood, assisting him in Siofra River, and collaborating with sorcerers Seluvis and Sellen. Each interaction progresses the story toward the Radahn Festival activation. This method typically requires 3-4 hours of dedicated quest progression but provides substantial narrative context and additional rewards beyond mere festival access.

The alternative approach utilizes the Grand Lift of Dectus, requiring collection of both Dectus Medallion halves. The left fragment resides within Fort Haight in Limgrave’s eastern peninsula, while the right half awaits discovery at Fort Faroth in Dragonbarrow. This method typically proves faster for players focused primarily on reaching Radahn quickly.

Once both medallion pieces are acquired, travel to the Grand Lift of Dectus located at the northern edge of Liurnia. Activating the lift transports players directly to the Altus Plateau, automatically triggering the Radahn Festival regardless of Ranni’s quest progression. This approach typically takes 1-2 hours depending on player navigation skills and prior knowledge of fort locations.

Before attempting the Radahn encounter, ensure your character reaches at least level 60-70 with appropriately upgraded weapons. The boss possesses devastating area-of-effect attacks and surprising mobility despite his massive size. Strategic use of the numerous summonable NPCs available during the fight can dramatically improve your chances of success.

Common mistakes include underestimating Radahn’s ranged capabilities and failing to utilize the mounted combat mechanics effectively. The battlefield’s open design intentionally accommodates Torrent, allowing players to evade many of Radahn’s deadliest attacks through mobility.

Optimization tips for advanced players include focusing on strike damage weapons, which Radahn exhibits particular vulnerability towards. Additionally, maintaining distance during his meteor phase and recognizing his attack patterns significantly reduces the encounter’s difficulty. Most players require 5-15 attempts to master the fight mechanics, though preparation significantly reduces this learning curve.
