Efficient Ways To Pay To Win

just here to drive the point home further, there is nothing guaranteed unless you sell the NX, every single other way of upgrading involves gambling with terrible odds against you.

You can buy protection scrolls and stuff in the CS, that's about the only thing though. And that's a terrible investment unless your equips are all worth $200 each anyway. Until your gear has 2+ lines of useful legendary pot, they're not worth protecting.
