What is the NAT 20 Rule?
The NAT 20 rule is a crucial concept in tabletop role-playing games, particularly in fantasy settings like Dungeons & Dragons (D&D). A NAT 20 is when a player rolls a 20 on a 20-sided die (d20) in certain situations, such as combat, skill checks, or ability checks. This article will delve into the ins and outs of the NAT 20 rule, its implications, and how it affects gameplay.
Direct Answer: What is the NAT 20 Rule?
A NAT 20 is when a player rolls a 20 on a d20, disregarding any modifiers or adjustments. This can happen in various situations, including:
• Combat: When rolling for attacks, damage, or ability checks
• Skill Checks: When attempting to perform a skill or ability
• Ability Checks: When rolling for ability scores or skill checks
Types of NAT 20s
There are two main types of NAT 20s:
- Natural 20 (NAT 20): A 20 on the d20, regardless of modifiers or adjustments
- Critical Success (Crit): A NAT 20 in combat or a situation where the result exceeds the target’s Armor Class (AC) by 10
How NAT 20 Affects Gameplay
The NAT 20 rule has significant implications for gameplay:
• Critical Hits: When a NAT 20 is achieved in combat, it results in a critical hit, dealing double damage (or triple damage with some abilities)
• Auto-Success: A NAT 20 can result in an auto-success in skill checks or ability checks, bypassing the need for additional checks or rolls
• Critical Failure: A NAT 1 can result in a critical failure, which can have detrimental effects on the player or the game
Rules and Exceptions
While the NAT 20 rule is straightforward, there are some exceptions and rules to consider:
• Opportune Parry and Riposte: In certain situations, a NAT 20 can result in a successful parry or riposte, negating the attack
• Other Effects: Some abilities, items, or conditions can alter the effects of a NAT 20 or 1
• GM Discretion: The Game Master (GM) may use their discretion to alter or ignore the NAT 20 rule in specific situations
Comparison with Other RPGs
While the NAT 20 rule is specific to D&D and some other fantasy RPGs, other systems may have similar mechanics:
• Rolling High: Some systems, like Pathfinder, have a similar concept where rolling high on a d20 can result in success
• Critical Hits: Other systems, like Savage Worlds, have critical hits that can deal bonus damage or have additional effects
Conclusion
In conclusion, the NAT 20 rule is a fundamental aspect of tabletop RPGs, particularly in D&D. Understanding the rule and its implications can greatly enhance gameplay and strategy. By mastering the NAT 20, players can gain an edge in combat, skill checks, and ability checks, leading to more exciting and unpredictable adventures.
