I thought this game will be fun, but not at all. At tutorial, this game will be fun but when I finished tutorial, this game is p2w. Summon is very low to get *3. Vampire need EXP vampire potion. Equipment drop very difficult to get A grade. And this is so grindy, I need thousand cube fragments to get 1 character. Stupid cube. If you tryhard grindy / want waste your money, this game is for you.
