|Average Cost To Upgrade|
|Star Level||Gems Used||Success Rate||Delicate Gems||Flawless Gems|
note that after level 3 it is cheapest to use 4 Gems each time you are upgrading.
I Chose to recommend using flawless gems at level 7 because the ratio of flawless to delicate is more consistent with drop rates, but feel free to change this slightly as needed. I would suggest saving up 2x as many as needed to upgrade an item to level 15 and then try because this is only an average, your results may vary.
The average upgrade cost per level = (the cost to upgrade to previous level + Gems used) / Success Rate
So if you use 1 delicate gem to upgrade to level 1 then the average cost to get to level 1 is:
1/.65 = 1.538 Delicate Gems
level 2 is:
(1.538+1)/.6 = 4.231 Delicate Gems
Starting at level 4 it gets a little more difficult, you must do the same thing then subtract level 1 cost * fail rate:
(9.51+4)/.8 – (1.538*.2) = 16.578 Delicate Gems
This is to account for not losing the average amount invested on that level down each time you fail
You stop doing this after level 8. Delicate and Flawless Gems must be calculated separately.
