Natural 20
The climax of almost every "I did something awesome, guys!" story on /tg/. A natural 20 is when you roll 20 on a 20-sided die (most commonly used by Dungeons and Dragons). In almost every system this is a critical success, meaning that whatever you did happens without question, even if it should be impossible for you to do based on your skill scores or stats. As such, it's a convenient way for a GM (or an OP) who's completely telling the truth about how the story went to make it go the way he wants.
Crits in Other Games
The Natural 20 signifies the crit, as stated above, which causes inhuman unnatural levels of goofiness and awesome. However, not all systems use the D20, so this handy list will try to encompass all of the Crit or Auto-Pass rolls for each system:
- GURPS:
- Warhammer Systems: A roll of 6 on a D6 will typically Auto-Hit or Auto-Wound, but not always.
- Dark Heresy: A roll of 1 on a D100, called a "Natural 1"
- Battletech:
- Pathfinder:
