On step 2 Collect 1 Research Notes 0/1 Kor-Sha Laboratory
Zam : In Kor-Sha Laboratory, kill some a worker's and loot Research Notes.
EQ Resources: Loot Research Notes from a Di`zok adherent or aruspex
I have completed all the steps and have difficulties getting this note. Killing multi-amount of mobs and could not get it drop. Here is the way to do it:
1) Put all your items from this quest in the bank.
2) Remove the quest and re-request it from Ingisitorma Varro
3) Zone into the Lab, through the door, not the cave
4) Kill the guardians at the zone-in. There are 2 of them. The Research Note should drop from them, loot it.
5) Go back to bank and collect back all the quest items you put there.
6) Hand each of them to a pet, and when you get it back it will update the task
7) Do the combine to get the Research Logbook
Go back to the Lab and redo step 1:
Kill some of the Kar`Zok 0/2 Kor-Sha Laboratory
In Kor-Sha Laboratory, kill Kar`Zok Sarnaks (green) until the task updates
9) Then hand-in and hail to complete the task.
The quest seems to be bugged, that the first Research Notes has to be the first drop (first step) you do. If you do other step first (once the task is updated once), you might not be able to get the Step 2 Research Note.
Hope this help.
