For the D2 one... It depends on if you hit them krouching or standing... Standing, you do the up arrow, like you did. Krouching, you do the straight arrow.
You kan also do F2D13~electric arrow, dash, d1~special...
I mentioned this in the other thread... But F2D13~electric arrow, B3 works... I just don't know if it's character specific, stance specific or what.... It's also pretty hard.
EDIT: I'll keep adding in electric arrow kombos.
