Talisman of Sargha is a Dragonflight toy that drops from Qalashi mobs in the Obsidian Citadel and scales your character up considerably, even in combat.
Guide awaiting review
Head to Obsidian Citadel
Travel to the Obsidian Citadel in the Waking Shores and make your way to the basement area at 30.09, 60.61, where Qalashi mobs are located.
Farm Qalashi Mobs
Grind the Qalashi mobs in the basement of the Obsidian Citadel. The drop has been seen multiple times in the same session, including twice for the same player, so continue farming the area around 34.57, 62.36.
Expand Your Farm Area
If you haven't seen a drop yet, extend your route to the nearby area at 36, 61 in the Waking Shores to cover more Qalashi spawn locations.
Tips
The toy scales your character up considerably and the effect persists in combat, but reverts to your original form while mounted.
The Talisman of Sargha is listed under the WoD expansion in the Toy Box in-game, despite being a Dragonflight drop — this is a known display quirk.
See the video guide for a visual walkthrough of the farming route.
