I played around with this so I can make possibly the least practical bleed build on Val, and I tried using Dead Cross after L1->L5. It extended the combo, but there were a few times when the enemy slipped out and punished it. From what I can tell, this can only happen if the opponent has a BB at full meter (or possibly a SM). Other than that, I'd say it's a reliable (somewhat lol) combo extender. Has anyone else found out when this will and won't work?
