Mythical guardian of death's gate resist reduction

Hello just a question, can curse of frailty proc the mythical guardian of death’s gate rr proc? Or do i need another attack? Thanks.

RR like that when it’s a regular stat on an item and not part of a proc is only applied through weapon attacks or skills/spells that have %weapon dmg (and will be scaled down below 100% effect if the %wd is less than 100)
so no, wont work on Curse of Frailty

thank you very much
