This worked for me before and I am just here to let everyone know of it. First I want to acknowledge that DBs are perfectly random, BUT this order of mets is a good sign. Yes I have only 1 post atm but it doesnt mean i'm a noob, ive been playing CO for very long. Anyway, heres the tip: Take your archer and go to slowapes, mini macs, but elf apes preferably. If you dont get a met by 750 kills then leave and move to another monster in AC. Not snakes tho they dont drop too good of stuff although i got a super lvl 30 dagger from them once but daggers suck theyre only worth like 5kk at super lol. So. You're in elf apes you should get a met every 250 kills maybe every 300. This is a good sign. I was there last week and i got a met every 250 kills religiously. after about the 9th or 10th met is a DB. So this is just a tip pretty much, if you have a pattern of mets coming in , dont stop. if you keep the pattern to the 9th or 10th met, give or take, then a DB is most likely on the way.
