Blade Waltz - Will now choose untargetable targets
Uh, what? I thought the whole point of being untargetable is to... you know.. be untargetable ?
Fiora's ult won't deal damage to untargetable enemies. If they used zhonya's before Fiora ults, she can't target them. Basically its to let Fiora get her full untargetable duration without preventing its counterplay.
Blade Waltz - Will now choose untargetable and invisible targets if necessary to continue Blade Waltz. If Fiora needs to jump to such a target to continue the Blade Waltz, she will do so, though Fiora will still fail to deal damage to untargetable/invisible units to which she jumps.
