4. Details: The critical hit chance modifier from Air's Embrace with Air Mastery does not appear to be working.
5. Steps to Reproduce:
   • Dex > 80 = 8%
   • Armor weak spot 80 = 5%
   • Longbow base chance = 5%
   • Equipment bonuses ~ 5%
   • Air's embrace 80, air mastery 60 = 7.5%
   • Observed crit rate: 828 crit out of 4482 bow attacks, suggesting a crit rate of 17.36% - 19.64% @ 95% confidence interval.
   • All formulas published by Port imply that with Air embrace, I should have a crit rate greater than 20%, but the formulas only work when AE is ignored.
