800+ Star Club
@Kesh thank you for the strategy it's appreciated.
However for myself at least the main question was more what bonus actually help as its not exactly clear from the descriptions.
Basically Are the collections needed for the event counted as quest items or not as the bonus we should use differ if they do or not.
Seems like we don't really have a definite answer to this though as some say one bonus help and others say the other one do
I found that what really helped is spyglass. Another poster said that is the only bonus she used and she got the quest finished early. I have all the items I need to complete the quest as of yesterday but I have not collected them yet. No need to hurry. Right now, I am just flying to 3-star Dahshur. The only destination I cannot 3-star on this quest is Paphos as I don't have enough beds and e-readers. I will start flying to my thurderbird excavations in a couple of hours.
I gotta say that compared to this quest and other quests, the Age of Ashes definitely had a bug in their program, at least on the Cold War collection.
