Completely dependent on luck. I got it on two characters, first time took 37 and 2nd time took 70-ish (both were before "another way to break the seal")
If you get bored of eod1 really easily (I know most people do...) my best advice is to just do 1-2 eod1 a day so you don't get too sick of it, until you collect the 50 cores. And if you're lucky enough for the ring to drop in less than 50, grats. But I wouldn't count on it.
Run eod1 a lot from lv.90-110; it'll be an easy way to level up and get merg at the same time (two birds with one stone, since leveling from 100-110 takes pretty long without eod1. Eod1 all the way up to 125 if you still dont have merg since LS exp isn't that great either).
