Sorry if this was known. I dont know yet how useful this may be, but it’s surely a nice addition to his arsenal, simply from the fact nobody will expect it.
HK into close HK is 1 frame link, and can stack up nice damage if opponent decides to not break, for example after shadow Skull Splitter or any stagger attack.
I recorded videos of it, but I am total cripple at video editing so I’ll post them when I learn basics.
