How do you complete the "How to get a powerful accessory 2" in the season pass? I've done my weekly 5k kill quest, I took a 3k kill quest from the black spirit and finished it and he doesn't have a chat option. Because it says daily old moon guild subjugation quest I did a guild kill quest too and it's still not completed.

Jetina's mission:

• Kill Quantity 3,000: any monster location

At first I failed at reading as well and thought it was any of the daily kill quests. Nope it's all regions or whatever. I slaughter those grass beatles. 

Jetina doesn't have a 3k kill quest. I even waited until reset and she still doesn't have it.

I have the same issue... i've killed 1500 polly and 2500 bashims so far, nothing completed. I coudnt find a "kill 3k" on jetina. only normal daily quests

You get this quest as alternative to normal daily quest from Jetina, it will be first on list of daily quest

jetina won't even talk to my season alt beyond the "I am Jetina, manager of the old moon guild" intro. what am I missing? 

IF you don't see this quest, and the BS is not talking to you, it is possible that you accepted a daily with her on another character and you will need to finish it or forfeit it to get this quest.

There is a requirement in order for this quest to show up, First open the Black Spirit & click on the quest called "A Cry for Help" complete that quest then select the quest "Old Moon Guild's Trade Offer"finish that quest & finish the quest "Shinning Brighter" After that you should be able to get "[Season] Old Moon Guild Special Monster Mission" That gives you the quest to grind out 3k mobs.

Just finished polly's .from a different char that acepted it then turn it in (could have cancelled and waited untill tomorrow but wtf :),

used Oo button / suggested / [Season] [lvl 60] Steps to greater heights / clicked the down arrow looking thing (quest acceptance condition) to open the BlackSpirit link then he gave me the quest with the Defeat 3,000 monsters. hope this helps
