The Cyclopedia says I can sell certain items to Yasir, but when I go to Yasir he won't buy those items. Why not?

Question

The Cyclopedia says Yasir buys certain items including:

• Broken halberd
• Spiked iron ball
• Zaogun shoulderplates
• Warmaster's wristguards

Why won't he buy them from me?

Answer 1

Yasir will only buy those items from you once you have completed the quest that allows you to sell them to Esrik. You will need to complete The New Frontier quest and hand in at least 9 tomes of knowledge to be able to trade these items to Esrik. After you have done so, Yasir will also buy those items from you.
