The game used to be good but greed ruined it beyond salvation, every new 5* demon released is more powerful than the last or adds some new pvp gimick, if you want a single copy of a 5* you need 18k-26k gems to do a 200-300 parchment summon To fully upgrade a single 5* you need 6 extra copies and now with Transcend (rolling gacha 1000-5000+ times to buff a single demon) whales get extra skill slots and extra stats and not a few but 500-800 extra attack points. Avoid this "game" like the plague.
