what the

is that like a final attack?? (video works for me)

that looks so cool

I believe it's the new assassin skill, "mark of assassin" (upgraded by "mark of night lord")
it works kind of like Xenon's triple counter point skill, but on things you attack. (mobs get a mark, hit them again, and it does damage (not sure if aoe) seems pretty straightforward)

also double flash jump yeeeeeeeee
