Oh sorry, I didn't notice you included in the original post that amber and Sare are using these. Like I said this changes some things around. With the WT you have on Ganyu, you can expect a 137.6805% increase in damage while the random set is expected to give you 154.224% more damage. However, just a little more crit rate on your WT set and you can equal this damage. About 6.745% more crit rate for the WT set and you can get equal damage to the random set you have. This is a total of 33.145% crit rate.

New calculations: WT: Crit: (0.264+0.20) * (198) = 91.872 Dmg bonus+crit: (0.91872 + (0.238745 * 0.91872) + 0.238745) * 100 = 137.6805

Random: Crit: (0.664+.20) * (178.5) = 154.224

How much crit rate do you need for WT to beat the random set. let’s set 0.264 = X and solve for X. (((0.264 + 0.20) * 198/100) + (0.238745 * ((0.264 + 0.20) * 198/100)) + 0.238745) * 100 > 154.224 (((X + 0.20) * 198/100) + (0.238745 * ((X + 0.20) * 198/100)) + 0.238745) * 100 > 154.224

(((X + 0.20) * 1.98) + (0.238745 * ((X + 0.20) * 1.98)) + 0.238745) * 100 > 154.224 Set (X + 0.2) = Y ((Y * 1.98) + (0.238745 * (Y * 1.98)) + 0.238745) * 100 > 154.224 (1.98Y + 0.4727151Y + 0.238745) * 100 > 154.224 (2.4527151Y + 0.238745) * 100 > 154.224 245.27151Y + 23.8745 > 154.224 245.27151Y + 23.8745 > 154.224 245.27151Y > 130.34949999999998 Y > 130.34949999999998/245.27151 = 0.531449820649777 X > 0.531449820649777 – 0.2 = 0.33144982064977696

So, keeping your crit damage the same, your crit rate for WT needs to be above 33.14 in order to beat the random set you have. Good luck.
