I’m working on modding some skills, and I wanted to share some tips that I’ve figured out, and hopefully get some answers for things I can’t figure out.
Skills pass AffixLevels to the Affix, and then the Affixes have a min and max value. I got inconsistent results (the final values of the affix when in game) when first messing with these numbers, but I figured out a way that always works. If you set Graph Override to “Linear_Graph”, then the final values are determined by the following equations:
Final Min = AffixLevel * Min / 100
Final Max = AffixLevel * Max / 100
So if you set the Min and Max values in the Affix to 200, then the you pass AffixLevel 1 for level 1 of the skill, and AffixLevel 2 for level 2 of the skill etc then the final skill will have a value of 2, 4, 6, 8, etc. This is exactly how block (Block and Parry) works, and how I figured out this method.
Another example for clarity.
Hope that helps.
