Oh, and to add one more thing since it's actually in the game. ALMOST universally, you use a 20 sided die to determine the result of ACTIONS. Such as attacking, searching, convincing, etc etc etc. In most systems, rolling a 1 on that 20 sided die is not only an automatic fail of whatever you were doing, but the person running the game will often add some kind of negative effect. You can see this happen in BTW when Hannah/Tharine attempts to do something at those ruins and "rolls a 1". Oscar tells her that she falls on her face and takes some damage.
The reverse of that is a "natural 20". Most of the time, this is an automatic success on whatever you're doing. In addition, you'll usually get some kind of bonus or perk. For example, if you roll a 20 while attacking, it's a critical hit which means you do more damage.
Just some extra info
