Equation 2.3. CA damage calculation for non crit hits:
Total damage when CA is granted = base damage * (1+ 0.15) * (1+ CHA bonus%) * (1+ CAbonus %) * (1+ blink dog %) * (1+ intellect devourer%)
Equation 2.4. CA damage calculation for critical hits:
Total damage with CA and CRIT = base damage * (1+ 0.75 + sum of all crit severity bonuses + 0.15 + CHA bonus + CAbonus) * (1+blink dog %) * (1+ intellect devourer %)
For example
Say I have 18 CHA (8% CHA bonus), CA bonus of 400 (converts to 4.9% from section 1.4), a purple blink dog and only base severity of 75%.
CA damage (non crit) = base damage * 1.15 * 1.08 * 1.049 * 1.05
CA damage (non crit) = base damage * 1.368, or you do 36.8% extra damage with CA
CA damage (crit) = base damage * ( 1+ 0.75 + 0.15+ 0.08 + 0.049) *1.05 = base damage * 2.029 * 1.05
CA damage (crit) = base damage * 2.13045
As you can see with crit attacks all the CA bonus is added to crit severity for some reason. It's unusual but it works in predicting damage dealt.
懒得翻译了，基本上初中英语过关的都看得懂吧，如果这篇文的公式没错，那么会有以下结论。
1.天生高魅力属性的职业是大爷（盗贼，法师，毒奶）
2.自带CA，或者能提供团队CA的职业是大爷（盗贼，变节法师，豹群游侠）
3.闪耀猎犬是神级伙伴
