[Question] Crashing Blow

So do i need a Crushing Blow affix (chance to take 25%hp of the enemy) before Crushing Blow Mythstone (chance to cast…) mounted in my items to take effect?

For Example. I have 6x epic items “without” crushing blow affix equiped in my rogue, then i put a Mythstone-Rebirth (increase chance to cast a crushing blow) on my armulet, so even without a crushing blow affix im still be able to cast a crushing blow? Or i need to have a crushing blow affix in my items before the mythstone-rebirth going to work?

“~and I’m also here just for the POPCORN…”

No you dont have to. Crushing blow is cap at 60% for your info

Mythstones are just working like affixes : you can get crushing blow MS without Crushing Blow Epic/Crystal
