Ok, so the first 2 are from my phone, why the sizing.
I was just doing a little grind on level 12 explores at Divinion Fields and got this last one. the first epic key of the 2 I have, I have no clue where I got but this was both not in the vault event. I checked by the end of the first one that added epic keys. and this last one. It was gotten about some days after the first event ended and I saw that I could open a epic vault as I’m doing my normal ones.
no clue if there is a trick to the chance or what. Every one in my guild has not even seen one yet. and I guess most of chat. course I know some of you have that are prob going to post under me at some later date lol. but ya… did not see that diamond drop coming… dont think i ever seen a 50 diamond drop on normal vaults ever… So ya… good luck to you all that are hunting for one!
last note, I dont ever really see normal vault keys drop when events not on. so i dont know if epic keys dont get a boosted chance from the event or the key has a higher one when the event is off.
