A critical hit with a shortsword.

When a creature rolls a natural 20 on an attack roll, the attack is a critical hit. Critical hits automatically land regardless of the target's AC, and the attacker also rolls twice the normal number of dice to determine damage dealt.

Mechanics

Any ability that uses an attack roll, including spell attacks, is capable of landing critical hits. Any dice that are rolled for damage, including additional dice such as those from smites or combat manoeuvres, are rolled twice. Abilities with multiple attack rolls like Scorching Ray Scorching Ray can have multiple critical hits, with each attack rolling independently of one another.

Flat modifiers and bonuses to damage – including the creature's relevant ability score modifier and proficiency bonus – are not doubled.

Maximizing critical hits

Any effect that triggers a re-roll of an attack die will increase the likelihood of landing a critical hit. Attacking with Advantage almost doubles the likelihood of rolling a critical.[1] Features that allow for situational rerolls, like Halfling Luck Halfling Luck, similarly increase the odds.

On the other side of things, effects that add dice or trigger re-rolls of damage die can make the most out of critical hits when they occur. These include:

Reducing critical threshold

Some feats, passive features, and items reduce the critical hit threshold by 1, allowing the creature to land critical hits by rolling either 19 or 20 on attack rolls. Multiple sources of this effect stack, allowing the critical hit threshold to go even lower than 19.

Guaranteed critical hits

There are also several ways to guarantee a critical hit.
