Lets say you have six dots between the Dex and firearms and your gun its damage 2. You roll 8d10 from your Dexterity and Firearms and Gun damage and count how much of those rolls were more than 6. The number of rolls you get are your successes then I determine what happened based on those successes. For example:<br/><br/>Dex: 3<br/>Firearms: 3<br/>Gun: 2<br/>4,5,6,6,7,7,6,7<br/><br/>you have 6 successes wich turn into damage.
