The term “natural 20” is a cornerstone of tabletop role-playing games, particularly Dungeons & Dragons (D&D), and it often elicits cheers, gasps, and a flurry of excited commentary around the gaming table. But what exactly does it mean, and why is it called “natural”? The answer lies in the distinction between the raw roll of a die and the modified results we often use in gameplay. A natural 20 specifically refers to the outcome when a 20-sided die (d20) lands with the face marked “20” facing upwards, without any modifiers influencing the result. In essence, it’s the purest form of a 20, unmodified by any stat bonuses or other adjustments. The term “natural” emphasizes that the 20 is achieved on the face of the die itself, distinguishing it from a modified result that equals 20.
The Importance of a Natural 20
The significance of a natural 20 stems from the rules of D&D, where certain events are triggered by rolling this particular number on a d20. Most importantly, on an attack roll, a natural 20 is an automatic hit, regardless of the target’s Armor Class (AC), often leading to a critical hit. The critical hit allows the player to deal additional damage, making this roll highly coveted and extremely powerful. The term “natural” sets it apart from, say, rolling a 15 and having a +5 modifier, which would also equal 20. This distinction is what gives a natural 20 its legendary status. It’s not just any 20; it’s the 20.
Why the Emphasis on “Natural”?
The emphasis on “natural” is about clarity and consistency in the game rules. In D&D, many rolls are modified by a character’s abilities, skills, or special effects. Without the term “natural,” ambiguity might arise when discussing whether a specific outcome of 20 was achieved through sheer luck (the face of the die), or if it was “manufactured” by adding to a lower roll. The term “natural 20” also provides an easy way for players and Dungeon Masters to immediately know that a game-changing critical success has occurred, adding to the drama and narrative of the game. It also helps set it apart from a normal success, as a “natural 20” often triggers additional actions and rewards.
Related FAQs about Natural 20s and Related Rolls
1. What is the difference between a “Natural 20” and a “Dirty 20”?
A “natural 20” occurs when the d20 lands with the number 20 facing up, and this number is not the result of modifications. A “dirty 20” (or unnatural 20) refers to a roll that equals 20 only after modifiers are added. For instance, rolling a 15 and adding a +5 modifier creates a dirty 20. While both results end up at 20, only a natural 20 triggers a critical success on an attack roll in many instances.
2. Does a natural 20 always guarantee success in D&D?
Yes, generally, a natural 20 is an automatic success for an attack roll. It will hit the target regardless of their AC and usually trigger a critical hit. However, a natural 20 on an ability check outside of combat does not guarantee an automatic success; it merely means you roll a 20, and modifiers need to be applied. If the end total is below the difficulty check (DC), you still might fail that check, unless a specific rule in the game you play states otherwise.
3. What is the opposite of a natural 20?
The opposite of a natural 20 is a natural 1, which typically results in an automatic failure on an attack roll. In many instances, a natural 1 on an attack roll might result in the player suffering a “fumble,” which can have an adverse or disadvantageous outcome.
4. Why is a natural 1 considered a critical failure?
In contrast to the guaranteed success of a natural 20, a natural 1 represents the worst possible outcome on a d20. This is why it is often treated as an automatic failure on an attack roll. This mechanic enhances the element of chance and risk in the game.
5. What is a critical hit caused by a natural 20?
A critical hit, often triggered by a natural 20, usually allows the player to roll additional damage dice. For example, if a character rolls a natural 20 with a longsword, they might roll two d8s instead of just one. Additional damage can also be added (non-dice damage), but only once, not doubled.
6. Do you always deal double damage on a natural 20?
While the basic rule of a critical hit is to double the damage dice, some variations exist across different editions of D&D and other tabletop role-playing systems. Some systems might have additional effects or modifiers for critical hits, so it is important to clarify your specific game’s rules.
7. Is a natural 20 an automatic success for Death Saving Throws?
Yes, on a death saving throw, a natural 20 is an automatic success, and also stabilizes the character and regains them 1 HP. This gives them a chance to fight another day.
8. What happens when you roll a natural 1 on a death saving throw?
Rolling a natural 1 on a death saving throw is extremely dangerous. It results in the character recording two failures instead of the normal one, increasing the risk of character death.
9. What are the odds of rolling a natural 20 on a d20?
The odds of rolling a natural 20 on a d20 are 1 in 20, or 5%. This relatively rare outcome is part of what makes it so memorable and impactful.
10. Can a natural 20 be beaten by a higher DC?
In most cases, no. On an attack roll, a natural 20 is an automatic hit regardless of the target’s Armor Class (AC). It also typically triggers a critical hit. In some games and systems, an exception may exist, but that’s typically for an ability check or save.
11. Does a natural 20 guarantee success on a skill check?
No, a natural 20 on a skill check means that the dice showed 20, but the modifiers still apply to this number. If the total after the modifier is not high enough to overcome the Difficulty Class (DC), the check is still a failure. Only a natural 20 on an attack roll has this automatic hit condition. However, some homebrew rules in certain games may change that.
12. Are there any rules or abilities that can negate the effects of a natural 20?
While very rare, some specific abilities or rules might exist in a specific D&D edition or homebrew rule that might, in an unusual circumstance, negate a natural 20, but that is generally unlikely.
13. Why is it sometimes referred to as a “crit” when a natural 20 is rolled?
“Crit” is short for “critical,” referring to the critical success that frequently accompanies a natural 20 on an attack roll. This often means the character inflicts additional damage by rolling more dice, enhancing the game’s combat.
14. Is the concept of the natural 20 the same in all tabletop RPGs?
While the natural 20 concept is a core element of D&D, other tabletop RPGs might have similar but different rules for critical successes. Not all games use a d20 or have automatic successes for specific rolls. Check each game’s rulebook for specifics.
15. Can you choose to fail a death save to get a natural 20 or natural 1 outcome?
No, you cannot choose to fail a death save. These are required rolls that are always made whenever a character is in danger of dying and not at 0HP. The outcome of the death saving throw is determined by the roll of a die.
By understanding the significance and nuances of the natural 20, players and game masters alike can fully appreciate the exciting and dramatic moments it often creates in tabletop role-playing games.
