You have 10 flat armor penetration, and 40% armor penetration. And the targets are affected by 30% armor reduction and 20 flat armor reduction,

Target A has 80 armor. The 80 is reduced to 56 by the 30% armor reduction. The 56 is reduced to 36 by the 20 armor reduction. The 36 is reduced to 26 by your 10 armor penetration. The 26 is reduced to 15.6 by your 40% armor penetration. 26 − (26 × 0.40) = 26 − 10.4 = 15.6        Target A takes damage as if it has 15.6 armor. Target B has 18 armor. The 18 is reduced to 12.6 by your 30% armor reduction. The 12.6 is reduced to −7.4 by your 20 armor reduction. The −7.4 is not reduced by your 10 armor penetration (cannot penetrate below 0). The −7.4 is not reduced by your 40% armor penetration (cannot penetrate below 0). Target B takes damage as if it has −7.4 armor. ...

Guys...no percentage is working when negative armor on target.... so if target has 20 armor, you have 30 armor penetration, it gets -10 armor and that's all. Clearly explained up there
