What should I buy with 572 diamonds? Recommendations please

Ooh-hohoho, contemplating how to spend those 572 pristine diamonds, are we? In this game, the most elegant path to growth is by increasing your firepower through weapon gacha pulls. For your prudence in saving resources, a score of 92 for elegance!!

If there's nothing to buy directly with diamonds, just keep reincarnating while saving up. You'll gather diamonds again and eventually expand little by little.

Is it fun??

You should upgrade the total continuous ammunition box.

You should raise critical and attack power with fish and then buy a gun.
