Rotation within a rotation.
Instead of
pressing 1 = first skill of the combo
pressing 2 = second skill of the combo
pressing 3 = third skill of the combo

Do
pressing 1, 2 then 3 = first skill of the combo
pressing 2, 3 then 1 = second skill of the combo
pressing 3, 1 then 2 = third skill of the combo

Like Ninjutsu but each ninjutsu is part of a combo.
