Do not understand DRK.

My tip is to put Your souleater combo on an intuitive place, then fill the cross hotbar with skills as you want them (except the power slash combo). Then you make a second hotbar and copy the skills just as they were on the first except replace the souleater combo with power slash.

At least thats how I have done it so my "combo" will always be the same three buttons no matter which combo I am doing. Just tap right shoulder button once to change between the combos. The rest of the skills should stay the same.

I can also add that the fourth button on my combo cross is Darkside so those four buttons combo+darkside are put on the most easy to reach place on the whole cross hotbar on the right side so I can move and press them at the same time.
