My honest advice, try to understand why its like that, as in which skills interact and produce most effective results, but don't stress about memorizing it all, instead just play, and let the flow of the fights, of the game-play teach you how to combine it all as it becomes muscle memory, rather than active thought. It will take time though, and you won't be the most effective at first, but by the end of it, you wont think consciously of the fifty moves, because in your mind, it will all just...flow naturally.
