How to complete the Elden Ring Sellen quest

Completing the Elden Ring Sellen quest can be a little tricky in some ways. Despite the fact that she's an early game NPC who you'll likely run into early on, a little like Kenneth Haight, you can't actually start the second stage of her story until much later in the game. You'll need to at least defeat Radahn, Rennala, and get to the Altus Plateau and find a hidden village filled with demi-humans.

That said, Selen's quest is the sorcery quest, and you get lots of powerful magical items and fancy-looking mage garbs by following it, such as the boss melting Comet Azur, and those big crystal headpieces you've probably seen knocking around. It's also how you get Selen's sorcery crown and Jeren's armor set, since his questline merges into this one once you defeat Radahn.

In this Elden Ring Selen quest guide, I'll explain every step in the sorcerer's story and what the potential rewards are for each. If you've managed to avoid spoilers all this time and still want to play blind, you might want to look away now.

Waypoint Ruins

How to start Sellen's quest 

You first meet Sorcerer Sellen at the Waypoint Ruins in Limgrave. She's located in the cellar there and you can access her room once you've defeated the Mad Pumpkin Head boss inside. Locate the door at the back of the cellar to find Sellen. Sellen will ask if you want to study under her and if you say yes, will sell Elden Ring sorceries and receive sorcery manuscripts. You need to accept this if you want to start her main quest.

You need to progress a lot further into the game to trigger the next part of this quest. You should also make sure you've beaten the main boss of the Raya Lucaria Academy, Rennala.

You need to head to the Hermit Village in Mt. Gelmir. To get here, head to the west side of the Altus Plateau, past the Wyndham Ruins, and look for the Seethewater River site of grace. Keep heading along the river, past the fort, and past the lava pool with Magma Wyrm boss. In the village you'll find a Demi-Human Queen boss, and just past it, Primeval Sorcerer Azur. Speak to them to get the Comet Azur sorcery. 

You can now head back to Sellen at Waypoint Ruins. Choose “Let us journey together” when prompted and she'll ask you to find another sorcerer. You also receive the Sellian Sealbreaker item.

Sellia Hideaway

How to find Lusat in Sellia Hideaway 

Now, head to Caelid. To the north-east of the Church of the Plague site of grace near Sellia, you'll find a graveyard guarded by a battlemage.  Find the tallest headstone and hit the wall to reveal the entrance to Sellia Hideaway.

Make your way through this dungeon, breaking through a few illusion walls until you reach the big room with the blue crystals and the Royal Revenant below. Make your way across the crystal bridge and drop to the lower one towards the end to take you back to solid ground. Hop across the gap and follow the wall of the cave until you spot another blue crystal bridge below to your right. You'll know if you're at the right place because there's a crystal snail sitting on it. 

From there, drop down to the area below. It's quite a long drop with a hostile sorcerer at the bottom, so be careful. Once it's been dispatched, use the Sellian Sealbreaker on the blue seal and venture down the tunnel to find Lusat at the end. You'll receive the Stars of Ruin sorcery.

Now return to Sellen at Waypoint Ruins and exhaust all of her dialogue options.

Witchbane Ruins

Find Sellen at the Witchbane Ruins 

To access the next step of the quest, you'll have to defeat Starscourge Radahn at Redmane Castle. 

Talk to Sellen and she'll ask you to head to the Witchbane Ruins in the Weeping Peninsula. It's located on the western half, directly south of the Fourth Church of Marika. If you spot the Walking Mausoleum, you are close. Head down to the cellar to find Sellen chained and talk to her to receive the “Sellen's Primal Glintstone” item.

Three Sisters

Locate the body at the Three Sisters

Next, you need to head to the Three Sisters near Caria Manor in West Liurnia. You should have unlocked this location and the site of grace during Ranni's quest, but if not, you'll have to venture through the manor and beat Royal Knight Loretta.

Look for some ruins located between Ranni's Rise and Renna's Rise. There is an illusory floor here in between the two rows of archways. Head down the steps and break through the illusory wall at the back of the room. You'll find Sellen's body here so transplant the Primal Glintstone when prompted.

Jerren

Speak to Jerren at Redmane Castle 

If you didn't speak to Jerren after defeating Radahn, do so now. You'll find him outside the door to the chapel where he'll tell you he's heading off to complete some unfinished business. If you already talked to him, return to Witchbane Ruins in the Weeping Peninsula.

Head back down into the Witchbane Ruins cellar and find Jerren here. He's killed Sellen's “body”. Talk to him to exhaust all his dialogue options once more.

Sellen or Jerren choice

Elden Ring Sellen or Jerren choice: Who should you side with? 

Now head to the Raya Lucaria Grand Library site of grace—where you fought Rennala. Head outside towards the lift, but don't take it. You should see two summon signs by the boss room door—one for Sellen, the other for Jerren. 

Now you have to choose who you want to help. Whichever one you pick will join you in defeating the other.

If you help Sellen to kill Jerren, you get: 

• Eccentric’s Armor set 
• Glintstone Kris dagger
• Shard Spiral sorcery (added to shop)
• Witch’s Glintstone Crown

If you challenge Sellen and have Jerren help you kill her, you get: 

• Ancient Dragon Smithing Stone
• Rune Arc
• Furlcalling Finger Remedy
• Selen’s Bell Bearing
• Witch’s Glintstone Crown

And that's it. Head back to the library to get your rewards, and to see what happens to Sellen.
