When combat starts, all combatants make an Initiative roll to determine the turn order. This is effectively a Dexterity Ability Check, but made using a D4 instead of a {{D20}}. Proficiency does not normally apply, but some class features, spells and magical items can provide bonuses to the Initiative roll.

= Advantage / Disadvantage =
 
Rolls can be modified by various bonuses and penalties.  These can take the form of adding or subtracting a value from the result, or requiring two rolls instead of one and taking the lower or higher of the two values.
 
== Advantage / Disadvantage ==
 
''Main page: [[Advantage]]''
''Main page: [[Advantage]]''


In various situations, a creature can have {{Advantage}} or {{Disadvantage}} on an Attack Roll, Saving Throw, or Ability Check.
In various situations, a creature can have {{Advantage}} or {{Disadvantage}} on an Attack Roll, Saving Throw, or Ability Check.


Advantage means that you make the roll twice and use the higher result. Disadvantage means you use the lower result.
'''Advantage''' means that you make the roll twice and use the higher result. '''Disadvantage''' means you use the lower result.
 
Advantage and Disadvantage cannot stack.  In other words, you never roll more than twice.  Additionally, they cancel each other out, no matter how many sources of Advantage or Disadvantage you have.  For instance, if you had three sources of Advantage and only one source of Disadvantage, they would still cancel each other out, causing you to roll normally.
 
== Ability Score Modifier ==
 
''Main page: [[Ability Score Modifier]]''
 
A creature's [[Ability Score]]s can modify the result of rolls, depending on how high or low the Ability Score is.  Which Ability Score is used to determine the Modifier depends on the roll that's being made.  The Ability Score Modifier for a specific [[Ability Score]] can also be referred to by the name of that Ability Score, such as: Strength Modifier, Dexterity Modifier, etc.
 
=== For Attack Rolls ===
 
Weapon attacks will generally use Strength or Dexterity, depending on the weapon and the type of attack made.  See [[Attack Roll]] for details.
 
Spell attacks will use an [[Ability Score]] depending on the [[Class]] of the creature making it.  Again, see the Attack Roll page for details.
 
=== For Damage Rolls ===
 
For Weapon attacks, the same rules apply to Damage Rolls as for Attack Rolls.  If the Damage Roll involves multiple dice, such as the 2d6 damage of a Greatsword, then the Modifier is applied to the total value, not to each individual die.
 
For the damage of Spells, there is generally no Ability Score Modifier, though there are exceptions to this rule.  For example, {{SAI|Agonising Blast}} allows the [[Warlock]] to add its Charisma Modifier to the damage of {{SAI|Eldritch Blast}}.
 
=== For Saving Throws ===
 
For saves against various threats, the threat in question determines which Ability Score is used to make the save.  For example, the {{SAI|Web}} spell requires you to make a Dexterity Save, whereas {{SAI|Crown of Madness}} requires a Wisdom Save.
 
=== For Difficulty Class ===
An Ability Score Modifier is also used in the Difficulty Class of a Saving Throw, such as by casting a spell.  The Modifier affects the Difficulty Class (DC) of the Save imposed on the target, using the formula:
 
<div style="text-align: center;">'''Spell Save DC = {{InfoBlob|8 + Spellcasting Ability Score Modifier + Proficiency Bonus}}'''</div>
 
This allows spellcasters to increase the effectiveness of their spells by increasing their [[Spells#Spellcasting_Ability_Modifier|Spellcasting Ability Modifier]], even when those spells do not involve Attack Rolls.
 
Note: The Ability Score used to determine the Spell Save DC is not necessarily the same as the type of Saving Throw imposed on targets.
 
=== For Ability Checks ===
 
An Ability Check is always based on a specific [[Ability Score]], which determines the [[Ability Score Modifier]] that will be used. One type of Ability Check is the [[Skill Check]], since each [[Skill]] is based on a specific Ability Score. For example, an Athletics Check uses [[Strength]], whereas a Sleight of Hand Check uses [[Dexterity]].
 
== Proficiency Bonus ==
 
''Main page: [[Proficiency Bonus]]''
 
Creatures can have Proficiency in a number of different areas, allowing them to add their {{SmallIcon|Proficiency Icon.png}} [[Proficiency Bonus]] to related rolls.  Proficiencies can be granted by a creature's [[Background]], [[Race]], [[Class]], and [[Feats]] chosen when leveling up.
 
=== For Attack Rolls ===
 
Attack Rolls made with [[Weapons]] can benefit from Proficiency with the type of weapon that's being used.  This kind of Proficiency can be granted by the creature's [[Race]], [[Class]], or [[Feats]] chosen when leveling up.
 
Attack Rolls made for spells benefit from Proficiency in spell casting, which all creatures capable of casting spells have.  The creature could have spell casting capabilities due to its [[Class]], or from a [[Feat]] it chose when leveling up.
 
=== For Saving Throws ===
 
A creature can have Proficiency in a specific type of Saving Throw, like Strength Saving Throws or Dexterity Saving Throws.  Each [[Class]] gains Proficiency in two such types of Saving Throw at level 1, and it can add their Proficiency Bonus to those types of Saving Throws.
 
=== For Difficulty Class ===
A creature's Proficiency Bonus also affects the Difficulty Class of the Saving Throw that enemies must roll when affected by that creature's spells (and some non-spell abilities).  The formula for this is:
 
<div style="text-align: center;">'''Spell Save DC = {{InfoBlob|8 + Spellcasting Ability Score Modifier + Proficiency Bonus}}'''</div>
 
=== For Ability Checks ===
 
An Ability Check may be based only on an [[Ability Scores|Ability]] rather than a [[Skill]], in which case no Proficiency Bonus is possible.  If it's based on a Skill, however, a creature will get a Proficiency Bonus in the corresponding Skill Checks if it's Proficient in that Skill.


Proficiency in a [[Skill]] can be granted by [[Race]], [[Class]], or a [[Feat]] chosen when leveling up. For example, all Elves have an innate feature called Keen Senses which grants them Proficiency in Perception.  Rangers can gain Proficiency in a number of skills based on class features they choose: Bounty Hunter grants Proficiency in Investigation, Keeper of the Veil and Mage Breaker both grant Proficiency in Arcana, and so on.  The [[Skilled]] Feat, if chosen when leveling up, allows a creature to gain Proficiency in any three Skills.
Advantage and Disadvantage cannot stack. In other words, you never roll more than twice. Additionally, they cancel each other out, no matter how many sources of Advantage or Disadvantage you have. For instance, if you had three sources of Advantage and only one source of Disadvantage, they would still cancel each other out, causing you to roll normally.
