For me, whenever I do eir frontal (the ass dash
), or any combo actually, I listen to the "beat" of each and every sound of its respective animation. For eir frontal, it'd be something like this:
*pretend this is like a music sheet x.x
*assume 1 = any skill of your choice
Eir frontal to the right:
What you see/hear..............: > > AS S > > AS 1
The actual button pressing: > > A SS > > A S1
I hope you understand this notation. Basically, you press 2 buttons or sequences of buttons in quick succession (not simultaneously) during the first button animation, then press the 3rd button during the 2nd button/button sequence animation and so on. Listening to the sound really helps a lot, so think of comboing as a sequence of rhythmic button presses.
