New Reboot Server. How Good?

You can get them for meso but you can also still get them for NX, as far as I can tell

So if you'd rather not grind for meso to buy them at the potion shop, cash is a shortcut.

Those are meso values. Red cubes are 12.5m, Black cubes are 22.6m. Their full price is at the top and the 1,250 and 2,260 are a result of the eastern method of grouping zeros in sets of 4 rather than sets of 3, it's 1,250 ten thousand mesos and 2,260 ten thousand mesos. You can get 5 red cubes (and only red cubes) through NX insofar as you get reward points from NX, but you can't directly buy anything like that for NX in Reboot. There are also no items with random rewards (gacha boxes, their version of style boxes)
