OG Vision SP2 not 100% power drain

5 star OG vision in aw versus node 42. My teammate has been fighting imiw and he hits him with the sp2, but power drain was not 100%. Does anyone have any explaination?

IMIW's armor passive reduces power drain/burn i think

i got it. 18% reduction per armor effect for power drain/steal. Thanks
