This game is fun for the earlier level then gets stupidly frustratingly hard in the mid 60s (from my experience) you NEED EARTH,WATER AND FIRE WEAPONS if you don't then you don't have enough damage you kill the enemies quick enough and you can't complete the challenges, i don't know how to ascend my 3 star weapon to a 4 star (the tutorial wasn't detailed enough) and rare resources becomes too rare at times (and diamonds are useless unless it's for stamina) uninstall might come back someday
