What's good people? I wanted to contribute in some way so here are the only two ways that I've been able to combo into Taokaka's Astral Heat (console version of course):
{1} 4B+C -> Astral Heat.
To do this one, do back throw and immediately hold the opposite direction (buffering the charge, you'll cross up, so you're already charging the correct way), time the rest of the motion to be completed the instant the opponent hits the floor. Tao should jump to the side of the screen, do her start up, and hit the opponent in mid air. Obviously a good player will tech the throw, but yeah.
{2} 6C (Charge) -> Astral Heat.
This one is even less practical, but if you do 6C (charge), and hold 4 while C is charging, and you by some miracle hit the opponent, then the Astral Heat will combo. I assume that you don't have to fully charge 6C, only the amount that the Astral Heat requires. I don't think you can combo off of just 6C without the charge.
I know these are kinda shitty set ups, but have you guys found any others?
