Ok so now it is confirmed that the Artifacs that drop of Cora are ALSO avail at the level four and even the level three area of covetous, somthing needs to be adjusted with Cora. Cora can take anywhere from 10 - 30 minutes to kill and only a small chance at recieving and artifact, with only a few items of any real value (that is if you even considering unravelling to relic frags valua) and a 1 hour spawn time between coras she is a COMPLETE waste of risk (work) vs reward. I can kill all of the critters in level 4 at least twice befroe i can even kill cora once and I have recieved more arties and have unravelled MANY MANY more relic frags than i could even dream of obtaiing from Cora? Soooooo in conclusion I, and I am sure many others have decided Cora just isn't worth it. Therefore Cora by her initial design is a COMPLETE waste of time.
