Diallos Quest In Elden Ring: Complete Walkthrough And Essential Rewards For 2026 Players

As of August 5, 2026, Elden Ring continues to maintain a massive player base, with Tarnished across the world still unraveling the tragic narrative of House Hoslow. Diallos, the younger son of the house, remains a pivotal NPC whose questline provides deep lore regarding the Volcano Manor and the fate of Jarburg. Completing this quest is essential for players seeking to obtain the Hoslow’s Petal Whip and the Mask of Hoslow, both of which remain high-tier gear options in the current meta.

Context & Background Section

Diallos first appears in the Roundtable Hold, lamenting the disappearance of his follower, Lanya. His narrative arc is tied intrinsically to the overarching politics of the Erdtree and the rebellion at Volcano Manor. Players initially encounter him at the Academy Gate Town in Liurnia of the Lakes, where he grieves over his fallen companion.

Following this encounter, Diallos relocates to the Roundtable Hold before eventually finding his way to Volcano Manor. Joining the Manor's assassination quests is a prerequisite for his progression. However, players must exercise caution; progressing too far into the Volcano Manor questline—specifically defeating Rykard, Lord of Blasphemy—will terminate Diallos's questline prematurely. By participating in the Manor’s requests and speaking to him regularly, players unlock the final phase of his story, which shifts the action to the peaceful settlement of Jarburg.

Impact & Utility Section

The primary utility of the Diallos questline lies in the acquisition of the Hoslow’s Petal Whip. This weapon is highly coveted by dexterity and status-effect builds due to its exceptional range and bleed buildup potential. In the current 2026 balance state of Elden Ring, dual-wielding this weapon alongside a second whip remains a top-tier strategy for both PvE content and competitive dueling.

Beyond the combat rewards, the questline is widely regarded as one of the most emotional side stories in the game. It humanizes the NPCs of the Lands Between, highlighting the themes of duty and sacrifice. Completing the quest to its conclusion—which involves defending the small pot-creatures of Jarburg—provides the player with the Diallos's Mask and the Numen's Rune, providing both cosmetic variety and a significant boost to the player's rune count. Failure to complete this quest results in missing out on the unique dialogue interactions with Jar-Bairn, the young jar who serves as the heart of the Jarburg community.

What's Next Section

With the Shadow of the Erdtree expansion having solidified the game's expansive legacy, players returning to the base game in August 2026 are often focusing on "completionist" runs. If you have already defeated Rykard, the quest is locked for your current playthrough. Players must ensure they complete the Diallos narrative before initiating the boss fight in the Audience Pathway.

For those currently navigating the quest, prioritize checking on the jars in Jarburg frequently. The quest progression in this final phase is time-gated by the player's rest cycles at Sites of Grace. If the progression stalls, fast-traveling to a different region and returning to Jarburg usually triggers the necessary world-state update. As the community continues to refine speedrunning routes and build optimization, the Hoslow set remains a staple of the Elden Ring experience. Whether you are aiming for the platinum trophy or perfecting your character’s appearance, follow the steps outlined above to ensure you secure these legendary items before your final ascent to the Elden Throne.
