  • Table of all crafting XP per level

    Took quite some work, 2 days of writing down how much items I crafted between levels and some curve approximations in Excel, but I'm quite confident that the XP per level formula is an elegant quadratic one:

    Code:
    10x^2 + 50x
    I've tested this for lvls 1-5, 24, 26, 31-38 and it always matches.

    So there you go, this should be the table with XPs for every crafting level. Better get started ;-).

    Thanks! Knowing I need 17k level 14 uncommons to finish helps me plan my time effectively.

              UmbraDei Thanks mate!

              Edit: Hang on, I have a really dumb question--how were you able to get the formula from the values in the table?

                Edit: Hang on, I have a really dumb question--how were you able to get the formula from the values in the table?

                i had a lot of approximate values in lvls 20-38, which were maybe 50-100 XP off due to counting errors and the perk where you can randomly get extra levels (and so extra XP). Using trendline fitting in Excel you can then check which trend works best and it turns out it was a quadratic one.

                The nice mathematical property of quadratic curves is that they are uniquely identified by 3 data points. So I started a new account with 0 crafting XP, wrote down *exactly* how much XP lvl 1-4 needed, and then calculated the corresponding formula. Checking that one back to earlier approximations of the lvl20+ numbers in some cases matched as close as 0.1%, so I'm highly confident it's correct.

                And also, the formula is elegant enough to be something a human developer would come up with.
