By "earn" on fuckula event, i meant win.
And on the same sentence, i wrote, "for what u understand you..." and i meant "for what i understand you..."
Sorry for mistyping / misthinking.
(Edit) I remember 1 more thing, i guess that that feature is deprecated. The temples allows you to boost your heroes stats, but when trying to unlock the 5th slot, to that you can add more heroes, to increase the tower boost, you need a """"moonstone"""", that does not even exist on the game, i unlocked the 4th slot, probably around the 4th world (cant remember exactly), i'm currently on the 15th world, and never seem a so called "moonstone" in the game.
