The gacha that actually started my interest in the genre after genshin failed to do so. You can simply grind the unit in the weekly dungeon if you're very unlucky, the pull rates are good, no dupe system nor weapons, Very friendly to low spenders and f2p cuz there's nothing to whale for.
Can't say i enjoyed it all that much but the plot was alright, the gacha rates are pretty good (even though you NEED duplicates ffs) and the rewards are pretty good. If you see it and it reminds you of cool old games, try iy out, i don't have the same nostalgia.
It's a gacha rate with, as per usual, pretty awful pull rates but if you play mihoyo stuff, it's basically the same. The story sucks ass at the beginning but gets aight by the midpoint, stayed for the combat, it's kino, and collecting chests activates something in my brain.
