Cryptek Harbinger of Storm

[CKO]

Does the - ap affect the haywire results?

Is it -3 or -2 with a glancing hit?

[TheGreatDalmuti]

You just get the glancing hit, then apply modifiers when rolling on the chart. The -2 for glancing for instance is applied at the same time when you would apply the -1 for Ap- .So yes you do apply it.
