Interestingly, the wiki page it links to seems to be missing now. If those numbers are correct, I should see an improvement of 2 in accuracy and defence if I improve luck by 5. I assume that's before diminishing returns?
I started to realize the depth of this game when someone pointed out the 2.5% proc damage per accuracy bonus of staves. I had completely ignored it as it seems a worthless stat. After building an Arcane Blade around proc / accuracy bonuses and seeing what ridiculous damage you can get, I suddenly realized that probably none of these stats should be ignored
