activate blood heat just when you hit max,
j.holdC,5holdC,j.holdC,5holdC,hold2C,2C,5C,623B,5B,623C,41236C (lol it connects)
the only useful thing about this is the knowledge that you can connect your bloodheat arc after your 623C, which is could be useful under unsual situations, cause you can just infinate combo them with her loop until you run low on blood heat then just finish it with that, but thats assumming you connect a hit sometime while your in blood heat, and still have a least 1/2 of it left.
