Where X is the number of dice you're rolling. You're unfortunately going to have to keep an eye open for 10's. If you get any 10's you can add 1 to whatever number you get per 10 you roll. So if you roll 5d10 and get 5, 5, 7, 10, 10, it would count 3 successes, but you'd really get 5 [plus the automatic successes from Epic Attributes and other factors.])
