Very good game, very good strategy and play. But they make it too hard to obtain characters, once you have a certain number of characters, it's repeat mode over and over... No matter the money you pay for the summoning tears. And to upgrade a character is also an Odyssey and via crucis. It's understandable that we won't have a new character all the time when we summon, but it's not.faur for the repeat to go on indefinitely and take out money. All the hype of hero trials for NOTHING.
