When a creature attacks another, | ''Main page: [[Attack Roll]]'' | ||
When a creature attacks another, the game rolls a D20. The result is modified by the attacking creature's [[#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. | |||
Result = {{D20}} + Ability Score Modifier + Proficiency Bonus | Result = {{D20}} + Ability Score Modifier + Proficiency Bonus | ||
Attacks done with [[Weapons]] always use an Attack Roll to determine success. Some spells also use an Attack Roll to determine whether they hit their intended target (such as [[Fire Bolt]] or [[Eldritch Blast]]), though other spells hit the target automatically (such as [[Magic Missile]] or [[Fireball]]). A spell that hits its target automatically may allow the target to make a Saving Throw instead; see below. | |||
The Attack Roll should not be confused with the Damage Roll, which instead determines the amount of damage done to a target by a successful attack. | |||
==== Modifiers ==== | |||
The [[Ability Score]] used for the Ability Score Modifier depends on the type of attack that's being made. Melee and ranged weapon attacks use Strength or Dexterity, depending on the weapon. For spells, the Ability Score used for the Modifier generally depends on the class of the caster; see the main [[Attack Roll]] page for details. | |||
For the creature's Proficiency Bonus to be added to the roll, the creature must be [[Proficiency|proficient]] in the kind of attack it's making. For weapon attacks, this is based on whether the creature has proficiency in the weapon being used. For spells, it's based on whether the creature has any innate spell casting capability granted by its class, subclass, or Feats. | |||
Attack Rolls can also have [[Advantage|Advantage / Disadvantage]]. | |||
==== Critical Miss / Critical Hit ==== | |||
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. Currently, a critical hit doubles all the damage dice involved in the damage roll, but not the modifiers. | |||
