When a creature attacks another, it rolls a d20. The result is modified by its [[#Ability Score Modifier|Ability Score Modifier]] and [[#Proficiency Bonus|Proficiency Bonus]]. If the result matches or exceeds the [[Armor Class]] of the target, then the attack is successful. Otherwise, it's a failure; this could mean the attack was a miss, failed to hurt the target due to its armor, or the target was able to dodge or parry. | When a creature attacks another, it rolls a d20.

As a special case, a roll of 1 means that the attack fails regardless of bonuses and the target's Armor Class. This is called a Critical Miss. Likewise, a roll of 20 means the attack succeeds regardless of the target's Armor Class. This is called a Critical Hit. A critical hit also affects the result of the Damage Roll, though the details of how this will be implemented in the finished game are not known yet. | As a special case, a roll of 1 means that the attack fails regardless of bonuses and the target's Armor Class.

Various actions, other than attacking or making a save, still require the creature to make an attempt that may fail. The creature rolls a d20, and adds its [[#Ability Score Modifier|Ability Score Modifier]] and possibly a [[#Proficiency Bonus|Proficiency Bonus]]. The attempted action has a specific [[Difficulty Class]] which the result of the roll must match or exceed. | Various actions, other than attacking or making a save, still require the creature to make an attempt that may fail.

Ability Checks can be based purely on an [[Ability Score]], in which case they can only benefit from the Ability Score Modifier, but not any Proficiency Bonus. More commonly, however, the check will be related to a specific [[Skill]], which not only determines the Ability Score used for the Modifier, but also lets the creature use its Proficiency Bonus if it happens to be Proficient in that particular Skill. In this case, the check may be called a '''Skill Check''' rather than an Ability Check. | Ability Checks can be based purely on an [[Ability Score]], in which case they can only benefit from the Ability Score Modifier, but not any Proficiency Bonus.
