Summoning is too rig and login crystal 10 is a ripe off. What are we going to do with just 10 crystal. All summon are 500 or 1000 but mostly 1000. Plus we got to spend 2000 crystal for special mission. Once beat all the story. There nonething left to get crystal of. It not worth wasting your money on this game. You be wasting money just for that character that you most likely won't use or wasting money on the character u already have. They need to add farm crystal after beat story over and over.
