Not sure I'm following what you are asking. That ability call should roll the attack, and if you have always roll damage enabled will roll the damage for that action as well. If you are asking how to roll for additional attacks on the NPC sheet, simply increment the $X to what ever the row number of the action you want is (actions are numbered starting at 0, so the second action would be $1). If you don't have always roll damage enabled, then clicking on the name of the action in the chat output should roll the damage. If that's not what you are asking, can you give a more detailed explanation of what you are trying to accomplish? EDIT: Specifically, I'm confused by "Now, how do i roll the damage from the info used from the sheet?".
