'''Attack Rolls''' are rolls that determine whether an attack hits a target. When making an attack roll, roll a d20 and add appropriate modifiers (Ability Scores Modifier, Proficiency Bonus).
''For a comprehensive summary of the mechanics behind all rolls and modifiers, see: [[Die Rolls]]''


The attacker succeeds if the total results matches or exceeds the target's [[Armour Class]].

== Attack Roll Modifiers ==
An '''Attack Roll''' happens when the game wants to decide whether an attack will hit its target.  This is different from a [[Damage Roll]], which instead determines the amount of damage done.  The Attack Roll uses a D20 and can be affected by [[Die Rolls#Modifiers|Modifiers]] such as the Ability Score Modifier and Proficiency Bonus of the creature making the attack.  The result of the roll, after Modifiers, is compared to the [[Armor Class]] of the target.  If the Armor Class is reached or exceeded, the attack is a successful hit and a Damage Roll is made.


* The common modifiers for making attack rolls with melee or ranged weapons are [[Strength]] (Melee) and [[Dexterity]] (Ranged).
As a special case, a roll of 1 means that the attack fails regardless of bonuses and target 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.
* Some [[Spell|spells]] require attack rolls and the modifiers added are determined by the spellcasters' [[Character Abilities#Spellcasting|spellcasting]] ability
 
** [[Wisdom]] for [[Cleric]], [[Druid]], [[Ranger]]  
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.
** [[Intelligence]] for [[Wizard]], [[Arcane Trickster]] (Rogue), [[Eldritch Knight]] (Fighter)
 
** [[Charisma]] for [[Bard]], [[Paladin]], [[Warlock]], [[Sorcerer]]
The [[Ability Score]] used for the 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:
* [[Proficiency#Proficiency Bonus Chart|Proficiency Bonuses]] are added when making an attack rolls with weapons or spells.
 
* Rolling 1 on an attack roll always misses the target, regardless of any modifiers that the attacker has.

* Rolling 20 on an attack roll always hits the target, ignoring the target's [[Armour Class]].
