Could someone say me how to execute properly Ossom's opener and Lucrezia's one? I'm just curious, I never heard by that names. (I suppose it's from mnks from this FC, if so, does it need a skill speed threshold?)

And then, aside from above question, I would like to know if there is any skill speed threshold to achieve something in special.

Thank you and keep the post going on, I really like the information you are posting!
