RELATED: Elden Ring: How to Get Celestial Dew and Revive NPCs
Starting the Radahn Festival is required to fight the boss in Elden Ring, where Radahn is stationed in Wailing Dunes. It allows players to summon many helpful NPCs to help in the boss fight. There are two ways Tarnished can start the festival and it’s up to fans to decide which path they prefer to take.
Updated September 12, 2022 by Erik Petrovich: There are two methods in terms of how to get to Radahn, or at least how to start the Radahn Festival that triggers his boss fight in the first place. Either by progressing through Ranni’s questline or by activating the Grand Lift of Dectus, players will alter Redmane Castle and be able to fight the demigod. Getting to Redmane Castle in the first place is just as important as knowing how to start the Radahn Festival. Starscourge Radahn is a fearsome foe, but getting to the area is just as tough as it’s full of T-Rex dogs, Radahn Soldiers, and other servants of Rot to get in your way. Learning how to get to Radahn means learning how to avoid being trampled and ripped open by these overwhelming enemies.
How to Trigger the Radahn Festival
There are two methods to trigger the Radahn Festival: progressing Ranni’s questline, or activating the Grand Lift of Dectus in northeastern Liurnia. Ranni’s questline is the easier of the two methods, though it does mean getting through Caria Manor. The Grand Lift of Dectus
Ranni the Witch Method
Ranni’s questline is the fastest way to reach Radahn. At the beginning of Elden Ring, players will find her in the Church of Elleh where she goes by Renna in a thinly veiled attempt at concealing her identity. Here she gives the Spirit Calling Bell, which enables the tarnished to summon helping Spirits. It’s not necessary to meet here here to start her questline, but it does shed light on the nature of this demigod.
To start Ranni’s questline proper, head to the Three Sisters just beyond Caria Manor in north Liurnia of the Lakes. It’s quite the trek to get here, made easier if you know that the higher western area of Liurnia is accessed via a hill near the Village of Albinaurics. In Ranni’s Rise, the central Rise in the Three Sisters, players can enter the service of the demigod witch.
After introducing yourself to the crew, talk to Blaidd in the Siofra River. He will send you to talk to Seluvis, Ranni’s Preceptor, who leads the player to Sorceress Sellen in the Waypoint Ruins Cellar of Limgrave. She will reveal the secret of Nokron - talk to Blaidd one more time in the Siofra River to trigger the Radahn Festival.
Grand Lift of Dectus Method
The Grand Lift of Dectus method for starting the Radahn Festival requires players find two halves of the Dectus Medallion. The first, and easier, of the two halves is found in Fort Haight, to the southeast of the Mistwood.
The second half is found in the Dragonbarrow, a particularly tough zone in northern Caelid. To get here, players can either take a slope leading up from Sellia, Town of Sorcery, or travel to the Bestial Sanctum and head south. The other half of the Dectus Medallion is located in Fort Faroth, on the southern cliffs of the Dragonbarrow overlooking Radahn’s boss arena.
After acquiring both halves of the Dectus Medallion, head to the Grand Lift of Dectus location in northeast Liurnia. Stand on the raised platform and press the interact button when the “Use Dectus Medallion” prompt appears. The lift will take Tarnished to Altus Plateau. Summon Torrent and sprint past the two Giants and head for the nearest Site of Lost Grace on the nearby hill.
Activate the Site and pass the time to Nightfall. This triggers the Radahn Festival, allowing players to travel to the Impassable Greatbridge bonfire and face Radahn.
How to Get to Radahn and Redmane Castle in Caelid
To find out where Radahn is in Elden Ring, players can talk to Blaidd at the conclusion of this segment of Ranni’s quest or speak with Alexander in Limgrave. Both characters hint at the festival in the Caelid Wilds – head to the Impassible Greatbridge Site of Lost Grace in southeast Caelid as shown above to find the Radahn Festival location. There are a lot of disfigured T-Rex dogs around here, as well as Radahn Soldiers, but they will lock into combat with each other after a few seconds, a window of opportunity for the Tarnished to break through to the Site of Grace.
Near the Grace, a Waygate can be seen. Interact with it to teleport inside the Redmane Castle - this only works if the player has started the Radahn Festival, though, and will not function if Redmane Castle is in its default state. You can tell if it’s active if there is a little portal contained within the Waygate and a special effect that resembles wind coursing through it.
Upon arriving, walk north and keep moving in the same direction until you see a huge open area ahead. Eventually, Blaidd can be found inside alongside several other champions. Interact with him, then go upstairs where Jerren, the Witch Hunter welcomes everyone to the Radahn Festival. Ask him to join the event, then turn around to the northwest and enter the big castle. Take the lift just outside of the rear door, and interact with the waygate to officially start the Radahn battle in the Wailing Dunes.
Elden Ring is available now for PC, PlayStation 4 and 5, and Xbox One and Series X|S.
