Oh, whoops, it’d be plus whatever the related skill/stat is. I guess I forgot to include that (let me do that now). Like for example if you’re trying to outrun an explosion and you roll three 6s and ALSO have 5 in speed, you’d get a 23 total which is an EPIC SUCCESS.
(… which means you run so fast that the explosion is trying to escape you?)
So not only do you totally succeed in outrunning the explosion, the triple 6s gives you a boost/advantage, AND the “epic” part means… I don’t know… you get to declare a story detail or something?
