I have purchase holy elemental the last two times it has appeared. I even purchased gems for this purpose. Each time I received Bane. Is this the only holy elemental hero?
Many many players had the same problem, same for me.
I know your pain, but there’s good news for you. It’s periodically.
I do 10x summon and get only 3 stars.
I get 2 epic token and get two 5 stars one after di other.
Bane is not the only holy/yellow hero, but he does seem to pop up a lot!
Consider it “luck of the draw”, alas.
