Jar-Bairn is one of the many NPCs you'll encounter that has an optional side quest in Elden Ring. For this part of our Elden Ring Wiki guide, you'll find details of where to find him, how to begin his questline, and the outcome of any choices you make that may impact his story.

Jar-Bairn was introduced to Elden Ring as part of Update 1.03., added as an NPC with a questline integrated with both Alexander the Iron Fist and Diallos. You can find him in Jarburg, just south of the Carian Study Hall in Liurnia of the Lankes. Upon entering the area from the south, look to the left to see him perched on the edge of a building's stoop.

Speak to Jar-Bairn

When you first speak to Jar-Bairn, he'll ask if you're to be the new Potentate for the village. To progress his quest, you must answer in the affirmative, although he will ultimately reject you for this role regardless. Exhaust his dialogue, and then reload the area and speak to him again to access the next leg of his quest.

Pick the Flowers

Upon reloading the area and speaking to him again, Jar-Bairn will tell you about the rare flowers growing in Jarburg and indicate that you're free to pick them. Pick a handful (you don't need to get every one) and then rest at the nearby site of grace.

Exhaust his dialogue again--this time concerning his uncle Alexander, presumed to be Alexander the Iron Fist--and then rest at the Site of Grace yet again to unlock more dialogue and the next leg of Jar-Bairn's questline.

Learn About the Poachers

Once you've unlocked Jar-Bairn's dialogue concerning poachers, reload the area to chat with Jar-Bairn again to learn that the new Jarburg Potentate has arrived. Head to one of the eastern shacks in the village to find the village's new Potentate, Diallos.

Speaking to Diallos here will reveal that he's found a new lease on life as the Potentate of Jarburg, and that he's happy to put his old life behind him. After you've exhausted Diallos' dialogue, leave Jarburg for a time to unlock the penultimate step of Jar-Bairn's quest.

The Sacking of Jarburg

Returning to Jarburg will reveal the slaughter of the pot denizens of the village (the only way this can be prevented is to completely avoid this questline to begin with). Find Jar-Bairn in the center of the path through the village, about halfway along; speak to him to learn that the poachers visited, but that Diallos valiantly fought them off. Look just beyond Jar-Bairn to see Diallos laying mortally wounded upon the ground.

After exhausting Diallos' dialogue and reloading the area, the Jar-Bairn will have moved to be next to Diallos' body. Speak to him here and then reload the area once more to find him back at his customary spot on the stoop of a village building. Exhaust his dialogue, wherein he will mention his hopes to set out on a journey to become a Warrior Jar. From here, you may now proceed to the final part of Jar-Bairn's quest.

Finishing Jar-Bairn's Questline

The final part of Jar-Bairn's questline links with the Alexander the Iron Fist Questline. If you have been keeping up with Alexander's questline, you will meet him in Crumbling Farum Azula, where he will challenge you to a duel.

To complete Jar-Bairn's quest, you must defeat Alexander and receive the key item Alexander's Innards. Return to Jarburg and present these to Jar-Bairn and reload the area one final time to receive the Companion Jar Talisman from where the Jar-Bairn had been sitting and officially end his quest.
