How to Find Diallos and Complete His Quest

Complete Diallos' quest in elden ring, from Roundtable Hold to Jarburg, to receive Diallos' Mask and Hoslow's Petal Whip.

First Meeting - Roundtable Hold

You will first encounter Diallos in Roundtable Hold, standing near the path to the balcony. He will speak briefly about himself and mention his missing servant, Lanya, describing her as a tomboy who has run off.

Second Meeting - Academy Gate Town, Liurnia

After reaching the Liurnia region and completing Stormveil Castle, Diallos will leave Roundtable Hold to search for Lanya. Head north from the Academy Gate Town Site of Grace in Liurnia. You will find Diallos northwest of this Site of Grace, standing over Lanya’s body. He will comment on a particular house. Lanya's death is unavoidable and a requirement for progressing Diallos' questline. Further progress requires access to Volcano Manor.

Third Meeting - Volcano Manor

Diallos can next be found in the Drawing Room at Volcano Manor, after you agree to join the Recusants. He expresses regret for his weakness and his decision to join them. Continue to speak with him and exhaust his dialogue as you complete the assassination contracts. After defeating the main boss of Volcano Manor, Diallos will depart.

Final Meeting - Jarburg

Jarburg is an optional village in eastern Liurnia. To reach it, start at the Artist’s Shack Site of Grace and head south along the cliff edge. Look for tombstones to drop down to Jarburg and its Site of Grace. You must first progress Jar-Bairn’s quest by speaking with the small jar NPC (non-player character — anyone the game controls, not you) outside a house and resting at the Site of Grace. Once Jar-Bairn mentions the new Potenate, go to the village. You will find Diallos tending to a small jar in one of the houses. Speak with him and exhaust his dialogue, then rest at the Site of Grace. You may need to rest multiple times or warp away and return to trigger the next event: Jarburg will have been attacked. You will find Diallos gravely injured. Speak with him and respond that he defended the jars well to ease his mind before he passes. Rest at the Site of Grace again, and you will find Jar-Bairn standing over Diallos. Exhaust Jar-Bairn’s dialogue, then rest at the Site of Grace one more time. You will then find Diallos’s Mask, Hoslow’s Petal Whip, and a Numen’s Rune.
