I only have two Epic Monsters so far, but during the promotions this month, I tried for Epic Toe Jammer and Epic Clackula. I failed every time, and now they’re gone. Meanwhile, these guys are the Epics the game decided to actually give me:
A literal fluke, I was trying for Knurv, and it happened to be during the Mythical promotions in early Anniversary Month.
First try, no torches, for no particular reason other than curiosity last Spooktacle. My brother told me Epic Ghazt was available and, seeing nothing else better to do, I looked up the combo and tried it.
Therefore, my conclusion is I can only get Epics if I don’t really want to get Epics. Basically, I’ll stop trying consciously to get them and just pick random combos until I get one.
I’m sure this strategy will work beneficially in every regard without a shadow of a doubt.
