Steps by Steps Guide
Note: You need to have completed Mansión Ravenholdt and have Ravenholdt reputation unlocked in order to begin this questline.
To obtain the Honor Among Thieves Rune, you need to follow a specific questline that begins once you've completed the Ravenholdt Manor quest and unlocked Ravenholdt reputation. Here's a step-by-step guide:
1. Initiate the Questline: When you reach Level 45 and enter a major city, you'll receive mail directing you to Ravenholdt Manor to speak with Fahrad.
2. Fool Me Twice: Go to Ravenholdt Manor and find Fahrad. He will inform you about the mysterious figure "C" and his activities.
3. The Talisman of Kazdor:
- Head to Zul'Farrak in Tanaris. You must complete this quest solo, as entering Zul'Farrak puts you into a special solo instance.
- Search tents to find two Clay Vessels containing 
Vile Concoction.
- Use one Vile Concoction near Antu'sul and loot the Bone Offering from Antu'Sul's Satchel.
- Use the other Vile Concoction near Witch Doctor Zum'rah and loot the Deadguard from Witch Doctor Zum'Rah's Satchel.
Witch Doctor Zum'rah and Antu'sul Location:
- Equip the Deadguard and loot the revealed grave for the Flesh Offering.
- Combine the Bone Offering and the Flesh Offering into a Blood Magic Essence.
- Find a small stone block at the foot of the steps leading up the pyramid in Zul'Farrak. Jump onto it, then walk onto the edge to reach a small chest containing a Hollow Emblem.
- Combine the Hollow Emblem and the Blood Magic Essence into a Blood Magic Emblem.
- Ascend the pyramid and loot the Spellbound War Chest to obtain Kazdor's Pendant.
4. Best Laid Plans: Return to Ravenholdt Manor and give Kazdor's Pendant to Zan Sivadento in the basement.
5. One Last Drop: Take the Modified Pendant to the dead drop in Pyrewood Village.
6. Biding Our Time: Finally, return to Fahrad at Ravenholdt to receive your Honor Among Thieves Rune as well as the Thief's Hood.
