The thrill of landing a critical hit in Dungeons & Dragons 5th Edition is unparalleled. It’s the moment when your carefully planned strategy culminates in a burst of damage that can turn the tide of battle. But how exactly do you reliably achieve these glorious crits? The most common way to score a critical hit in 5e is by rolling a natural 20 on your attack roll, but savvy players and DMs alike know that there are other, often more potent, methods to increase their chances or even guarantee a critical hit.
The Core Mechanic: Rolling a Natural 20
At its heart, the critical hit mechanic in 5e is elegantly simple. When you make an attack roll, whether it’s with a sword, a bow, or a spell requiring an attack roll, and the d20 shows a 20 before any modifiers are added, you’ve scored a critical hit. This natural 20 automatically hits, regardless of the target’s Armor Class (AC). This is where the fun begins, as it unleashes the doubled damage.
Doubling the Dice: The Damage Calculation
The standard rule for a critical hit is that you double the number of damage dice rolled for the attack. For example, if you crit with a longsword, which normally deals 1d8 slashing damage, you would roll two d8s and add them together. Then, you would add any relevant modifiers, such as your Strength modifier or any magical bonuses on your weapon.
It’s important to note that you only double the dice. Flat bonuses, like the +3 from a magical weapon or the extra damage from a feature like Hunter’s Mark, are added only once. This means that the more dice you roll for damage, the more impactful your critical hit will be. Classes and builds that stack damage dice, like Rogues with Sneak Attack or Paladins with Divine Smite, are particularly devastating when they crit.
Beyond the 20: Expanding Your Critical Potential
While rolling a natural 20 is the most common way to achieve a critical hit, it’s also the least reliable. Relying solely on the 5% chance inherent in a d20 roll means you’ll be waiting a long time for that sweet, sweet crit. Fortunately, there are several ways to circumvent this reliance on chance and increase your critical hit potential significantly.
Exploiting Conditions: The Guaranteed Crit
The most reliable way to guarantee a critical hit is to exploit certain conditions that automatically turn a successful attack into a critical hit. The two primary conditions that grant this effect are:
- Paralyzed: A paralyzed creature is incapacitated and unable to move or act. Any attack that hits a paralyzed creature is automatically a critical hit.
- Unconscious: An unconscious creature is incapacitated, can’t move or speak, and is unaware of its surroundings. An attack that hits an unconscious creature is automatically a critical hit.
These conditions are powerful, and setting them up often requires teamwork, specific spells, or class features. For example, a spellcaster could use Hold Person to paralyze a humanoid, setting it up for a devastating critical hit from a melee attacker.
Advantage: Stack the Odds
While advantage doesn’t guarantee a critical hit, it drastically increases your chances. When you have advantage on an attack roll, you roll two d20s and take the higher result. This effectively increases your chance of rolling a natural 20 from 5% to approximately 9.75%. While not a massive jump, over the course of a combat, these increased odds can significantly boost your crit rate.
Several factors can grant advantage, including:
- Flanking: When a creature and at least one of its allies are flanking an enemy, they both have advantage on attack rolls against that enemy. (Note: Flanking rules are optional and may not be used by every DM.)
- Specific spells and abilities: Many spells and class features grant advantage on attack rolls, such as the Faerie Fire spell, which gives advantage to attack rolls against creatures affected by it.
- Help action: A character can use their action to Help another character, granting them advantage on their next attack roll.
Expanding the Critical Range
Some classes, subclasses, and magic items can expand the range of numbers that trigger a critical hit. Instead of only critting on a natural 20, you might crit on a 19 or 20, or even an 18, 19, or 20. This significantly increases your critical hit chance.
Examples of features that expand the critical range include:
- Champion Fighter (Improved Critical): The Champion fighter subclass gains the Improved Critical feature at 3rd level, which allows them to score a critical hit on a roll of 19 or 20.
- Hexblade Warlock (Hexblade’s Curse): The Hexblade warlock gains the Hexblade’s Curse feature, which, among other effects, allows them to score a critical hit against the cursed target on a roll of 19 or 20.
- Certain Magic Weapons: Some magic weapons have properties that expand the critical hit range.
These features are highly sought after, as they provide a consistent and reliable way to increase your critical hit frequency.
Optimizing for Critical Hits: Building the Crit Machine
If you want to truly maximize your critical hit potential, you need to build your character around the concept. This involves choosing classes, feats, and equipment that synergize to increase your critical hit chance and damage.
Here are some tips for building a critical hit focused character:
- Choose classes that synergize with critical hits: Classes like Paladin, Rogue, and Barbarian excel at delivering burst damage, which is amplified by critical hits. Consider multiclassing to combine the benefits of different classes.
- Prioritize advantage: Look for ways to consistently gain advantage on your attack rolls. This could involve choosing spells and abilities that grant advantage, or coordinating with your party to set up flanking opportunities.
- Maximize damage dice: Focus on features and abilities that add extra damage dice to your attacks, such as Sneak Attack, Divine Smite, or Hunter’s Mark.
- Seek out expanded critical range: If possible, acquire magic items or class features that expand your critical hit range.
- Consider Feats: Certain feats like Great Weapon Master (if you plan to build a strength based melee class) can help you secure additional bonuses to your damage or crit potential.
By carefully planning your character build and playstyle, you can become a critical hit machine, capable of unleashing devastating bursts of damage that will leave your enemies reeling. Don’t forget to check out Games Learning Society for more D&D tips and resources!

Frequently Asked Questions (FAQs)
1. Do critical hits automatically hit in 5e?
Yes, in D&D 5e, a natural 20 on an attack roll automatically hits, regardless of the target’s Armor Class (AC). A critical hit will always hit.
2. How do you calculate critical hit damage in 5e?
When you score a critical hit, you roll all of the attack’s damage dice twice and add them together. Then, you add any relevant modifiers, such as your Strength modifier or magical bonuses.
3. Do spells get critical hits in 5e?
Yes, spells that require an attack roll can score critical hits in 5e. The damage dice are doubled just like with weapon attacks.
4. What conditions cause automatic critical hits in 5e?
The two main conditions that cause automatic critical hits are being Paralyzed or Unconscious. Any attack that hits a creature with either of these conditions is automatically a critical hit.
5. How can I increase my chance of getting a critical hit in 5e?
You can increase your chances of getting a critical hit by gaining advantage on your attack rolls or by using features that expand your critical hit range, such as the Champion Fighter’s Improved Critical feature.
6. Do critical hits ignore damage reduction or resistance in 5e?
No, critical hits do not ignore damage resistance. The damage is simply doubled before resistance is applied. They also do not ignore damage reduction which is percentage based “armor”.
7. What happens if a creature is immune to critical hits in 5e?
If a creature is immune to critical hits, it takes normal damage instead of double damage when hit by a critical.
8. Can a natural 1 be a critical failure in 5e?
Strictly speaking, Critical Failures don’t exist in 5E. There are three kinds of d20 rolls: attack rolls, ability checks, and saving throws. However, ability checks and saving throws do not automatically fail on a natural 1. On an attack roll, a 1 always misses.
9. What is the range of a critical hit in 5e?
The default range for a critical hit is a roll of 20 on the d20 attack roll. Some features can expand this range to include rolls of 19 or even 18.
10. Do critical hits affect all types of attacks in 5e?
Critical hits can affect any attack that requires an attack roll, including weapon attacks, spell attacks, and some special abilities.
11. Does sneak attack damage get doubled on a critical hit?
Yes, if a Rogue scores a critical hit with an attack that includes Sneak Attack damage, all the Sneak Attack damage dice are doubled.
12. If I have multiple sources of extra damage, do they all get doubled on a critical hit?
Only the damage dice are doubled on a critical hit. Flat bonuses to damage, such as the +3 from a magic weapon, are added only once.
13. Are there any feats that specifically enhance critical hits in 5e?
While there aren’t feats that specifically enhance critical hits, feats that increase your chance to hit (like Sharpshooter or Great Weapon Master) can indirectly increase your chances of scoring a crit with advantage. Also Great Weapon Master can add additional damage.
14. How does the Help action interact with critical hits?
The Help action grants advantage on the target’s next attack roll. Advantage increases the chance of rolling a natural 20 and scoring a critical hit.
15. Can I confirm a critical hit in D&D 5e?
No, there is no confirmation roll for critical hits in D&D 5e. If you roll a natural 20 on an attack roll, it is automatically a critical hit. The confirmation roll was something found in earlier editions of the game.
