'''Spells''' are magical energies from the multiverse conjured by spellcasters ([[Wizard]], [[Sorcerer]], [[Druid]], [[Warlock]], etc.) through experience, knowledge, or innate ability to create magical [[Condition|Effects]], deal damage to enemies, or heal their allies.
'''Spells''' are magical effects that are created by creatures via '''spellcasting'''.{{note|The term ''spellcasting'' refers {{em|both}} to the act of casting spells, as well as the Spellcasting class feature. The latter is always capitalised, whereas the former is generally not.}} Spells are frequently cast to deal [[Damage mechanics|damage]] and provide [[healing]], or to inflict [[condition|conditions]] on the targets.
''See: [[Spells#Spell Properties Table|List of all spells]]''
All [[Class|classes]] are capable of casting spells with the help of [[Scrolls|scrolls]] and [[Equipment|magic items]], and classes with the Spellcasting or Pact Magic features – called ''spellcasters'' – have spell slots they can expend to cast spells they know, without the need for scrolls.
All spellcasters are [[Proficiency#Proficiency Bonus Chart|proficient]] with Spell Attacks. When they make an '''Attack Roll''' with a '''Spell''', they roll against the target's [[Armour Class]] (or AC):
Spells are created from the Weave, the magical energies of the multiverse. They are conjured through experience, knowledge, or innate ability, or via the use of scrolls and magical items.
Spells which do not invoke an '''Attack Roll''' often require the target to roll a [[Saving Throw]] against the spellcaster's spellcasting [[Difficulty Class]] (or DC):
=== Spell levels ===
All spells have a level – a measure of its power and difficulty to cast. To cast a spell, the caster must usually expend a [[Spells#Spell slots|spell slot]] of sufficient level. Spells cast from scrolls {{em|do not}} consume spell slots when cast, nor do most spells granted by magic items.
Level 0 spells are called ''cantrips'', and can always be cast at will, without expending a spell slot.
== Spell Slots ==
=== Spellcasting ability ===
'''Spell Slots''' are the spellcasters' [[Resource]] used to cast '''Spells'''. Once '''Spell Slots''' are depleted, they can only be regained through a [[Long Rest]], with the following notable exceptions:
Every class – including those without the Spellcasting feature – has a designated [[Ability scores|ability]] known as their ''spellcasting ability'', which represents their capacity to cast spells.{{note|Some spells designate a specific spellcasting ability regardless of the class casting them. This is most commonly a result of spells obtained via racial features. [[Arcane Trickster]] Rogues and [[Eldritch Knight]] Fighters gain the Spellcasting feature as part of the subclass selected at Level 3.}}
* Certain classes like [[Wizard]] and some [[Druid]] subclasses have the ability to regain a small number of '''Spell Slots''' once per Long Rest.
* [[Warlock]]s only need to take a [[Short Rest]] to fully regain their Spell Slots.
=== Spell Slot Levels ===
{{table list|
Each Spell Slot has a level that corresponds to the level of spells that can be cast using that slot: {{Icon|4 Level 1 Spell Slots.png}} Level 1, {{Icon|2 Level 2 Spell Slots.png}} Level 2, {{Icon|2 Level 3 Spell Slots.png}} Level 3, and so on.
When casting a spell, the spellcasting ability used depends on whether the spell was learned (first two points below) or cast from an item.
* Spells learned from taking levels in a class will use that class' spellcasting ability modifier.
* Spells learned from scribing a scroll into your Spellbook count as Wizard spells (because learning from scrolls is a Wizard feature) and thus use Intelligence.
* Spells from other sources (including items, [[Illithid Powers]] that require a saving throw, and using scrolls directly from inventory) use the spellcasting ability of the class the creature most recently took a {{em|first}} level in.{{note|A character who starts with 5 levels in [[Sorcerer]] will use Charisma for all of their sorcerer spells, as well as spells granted by equipment (e.g. the Firebolt cantrip granted by the [[Gold Wyrmling Staff]]) and spell scrolls. If this character at level 6 takes their first level in [[Wizard]] then their Wizard spells (including spell scrolls scribed into their Spellbook) will use Intelligence, their Sorcerer spells will continue to use Charisma, but spells granted from equipment and spell scrolls cast directly from inventory will now use Intelligence. If the character at level 7 takes their sixth level in Sorcerer then nothing changes, because Sorcerer is not a "new" class on this character. However if the character at level 8 now takes their first level in [[Druid]] then their Sorcerer spells continue to use Charisma, their Wizard spells (including scrolls scribed into their Spellbook) continue to use Intelligence, their Druid spells now use Wisdom, and spells granted by equipment and scrolls cast directly from inventory now use Wisdom since Druid is a "new" class on this character.}}
== Spell properties ==
Each spell belongs to a school which defines its general purpose, and all spells have a range at which they can be cast, and a specified target or [[Area|area of effect]]. A spell may have an instantaneous effect when cast (for example a magical attack), or a spell may have an effect which persists for a specified ''duration'' (measured in ''turns'').
Most spells can be interrupted by {{SAI|Counterspell}} before they are cast, and most spells cannot be cast by {{Cond|Silenced}} creatures.
=== Schools of magic ===
{{confused with|Wizard|custom=the Wizard School class feature.}}
Every spell belongs to one of eight schools of magic: [[abjuration]], [[conjuration]], [[divination]], [[enchantment (school)|enchantment]], [[evocation]], [[illusion]], [[necromancy]], or [[transmutation]]. Some class features only benefit spells of a specific school.
=== Casting time ===
All spells have a casting time that determines whether it requires the caster to take an {{r|action}}, a {{r|bonus}}, or a {{r|reaction}}. Most spells require the caster to take an action.
=== Spell saves ===
Harmful spells which {{em|don't}} require an attack roll, such spells that target an area or a specific point in space – or that affect a target directly – often allow targeted creatures to attempt a [[saving throw|save]] against the spell, potentially ignoring or reducing the spell's effect.
The [[Difficulty Class]] (DC) of these saves – called the ''spell save DC'' – is generally based on the caster's spellcasting DC:
Cantrips {{Icon|Cantrips Icon.png}} do not consume any spell slots and are effectively an infinite resource.
; Examples of spells that require saves:
* {{SAI|Grease|h=20px}}
* {{SAI|Fireball|h=20px}}
* {{SAI|Hold Person|h=20px}}
Due to their unique mechanics, the spell slots of a [[Warlock]] are colored differently, like so: {{Icon|Warlock 2 Level 1 Spell Slots Icon.png}}
Certain [[List of equipment that affect Spell Save DC|equipment]] worn by the caster can also affect their Spell DCs.
=== Upcasting ===
=== Spell attack rolls ===
'''Upcasting''' refers to when a spellcaster chooses to use a higher level spell slot to cast a lower level spell. Many spells gain additional damage dice, area of effect, targets, or other effects when upcast, but some spells gain no additional benefit. [[Warlock]] spells are '''always''' upcast to their highest known spell level.
Some harmful spells – typically those cast in the form of rays or as projectiles – require the caster to make an [[Attacks|attack roll]] against the target's [[Armour Class|AC]] in order to determine if their spell attack is a hit or a miss.
=== Spell Slot Amount ===
The caster adds their spellcasting ability modifier, as well as their proficiency bonus, to the results of the attack roll:
The total amount of spell slots a spellcaster would get is dependent upon their '''Effective Spellcaster Level (ESL).''' For full spellcasters ({{Class|Bard}}s, {{Class|Cleric}}s, {{Class|Druid}}s, {{Class|Sorcerer}}s, and {{Class|Wizard}}s) this is exactly their class level (A level 5 wizard has an Effective Spellcaster Level of 5); "Half-spellcasters" ({{Class|Ranger}}s and {{Class|Paladin}}s), are not considered spellcasters until class level 2, at which point their Effective Spellcaster Level is their class level halved. "One-third-spellcasters" ({{Class|Arcane Trickster}}s and {{Class|Eldritch Knight}}s) are all subclasses that can only be taken at class level three, their Effective Spellcaster Level is their class level divided by three. For the purpose of determining Spell Slot Distribution the Effective Spellcaster Level is '''rounded up'''.
<!-- In 5e, ESL of a multiclassed character rounds down immediately after division and the results are then summed up. We don't know how Larian handles multiclassing yet, So I've elected to omit this detail. -->
Once the '''Effective Spellcaster Level''' is known, one can consult the following table to find out their character's spell slot distribution:

==== Ending concentration ====
[[File:Concentration_Example.webp|thumb|upright|right|Concentration icon in the hotbar. Clicking "X" will end concentration.]]
Although concentration normally lasts for a spell's full duration, or until another concentration spell is cast, there are multiple ways for concentration to break:
; Manually : Concentration can be ended by the player at any time via the “X” on the current concentration spell's icon, displayed next to the caster's main portrait.
; Taking damage : Any time a creature concentrating on a spell takes damage, they make a Constitution save against a DC equal to half the damage taken, or 10, whichever is higher.{{note|Constitution saves are sometimes erroneously referred to as a ''Constitution checks''.}} If the save fails, concentration ends.
; Conditions : Some conditions – such as {{Cond|Downed}} or {{Cond|Sleeping}} – also end concentration, without allowing a save.
; Long rests : Taking a [[Resting|long rest]] ends concentration.
; Dismissing companion : Sending a companion to camp or otherwise removing them from the active party ends their concentration.
== Spellcasters ==
Spellcasters can either be ''full casters'' – meaning they can learn up to 6th level spells, ''half casters'' – meaning they can learn up to 3rd level spells, or ''one-third casters'' – meaning they can learn up to 2nd level spells. Non spellcasters do not gain or add spell slots.
* {{Class|Rogue}} (other than [[Arcane Trickster]])
* {{Class|Fighter}} (other than [[Eldritch Knight]])
=== Known spells ===
Known spells are spells generally learned from taking levels in a class with the Spellcasting or Pact Magic features. Each caster class has access to its own list of spells, though there is significant overlap between classes.
The following classes must learn spells through leveling up:
* {{Class|Arcane Trickster}}
* {{Class|Bard}}
* {{Class|Eldritch Knight}}
* {{Class|Ranger}}
* {{Class|Sorcerer}}
* {{Class|Wizard}}
* {{Class|Warlock}}
These classes, with the exception of wizard, also have access to the Replacement Spell feature, which allows them to swap a known spell each time a new level is taken in them. Wizards can instead learn new spells from scrolls, without needing to give up an already known spell.
The following classes automatically learn all their available spells when a level is taken in them:
* {{Class|Cleric}}
* {{Class|Druid}}
* {{Class|Paladin}}
[[File:Wizard-spellbook.webp|thumb|A Wizard's Spellbook window: it allows you to change prepared spells outside combat]]
=== Prepared spells ===
[[File:Prepared Spells Icon.webp|24px]]
Some casters – known as ''prepared spellcasters'' to set them apart from ''spontaneous spellcasters'' – must ''prepare'' a smaller selection of their known spells to cast them. Spells can be prepared at any time except during combat.
Prepared spellcasters include:
* {{Class|Cleric}}
* {{Class|Druid}}
* {{Class|Paladin}}
* {{Class|Wizard}}
The number of prepared spells each class can have at a time is equal to {{InfoBlob|spellcasting ability modifier + class level}} (minimum of 1).
Additionally, spells granted by [[Race|racial features]] or by certain class features (such as by [[Cleric|cleric Domains]]) are considered ''inherent'' and are always prepared.
Some spells with ongoing effects that do not require concentration, like {{SAI|Speak with Animals}} or {{SAI|Aid}}, must remain in the caster's prepared spells list after being cast, or their effects will end.
=== Spell slots ===
All spellcasters have spell slots, which they expend to cast their known spells. Cantrips {{SpellSlot|cantrip|w=24}} do not expend spell slots and can be cast at will. Depleted spell slots are generally replenished by taking a [[Long Rest]] ([[Short Rest]] for Warlocks), though there are methods of [[List of sources of additional resources#Spell slots|creating additional slots, or replenishing expended ones]].
A spell of a given level requires a spell slot of the same level or higher to be expended to cast it. Many spells will be {{Icon|Upcast Icon.png|24px}} [[Upcasting|upcast]] when cast with a higher spell slot, making them more powerful. Even if it gains no other benefit, a spell always counts as a spell of the level of the slot used to cast it.
The number of spell slot for each level across ESL has no clear pattern, but when a spell level opens up does have an identifiable pattern. '''The maximum spell level a spellcaster has access to is their ESL halved and then rounded up.'''
A caster's available Spellcasting spell slots are determined by the caster's ''effective spellcaster level'' (''ESL''). A full caster's ESL is exactly their class level, whereas the ESL of half-casters and one-third casters is equal to half and one third their level, respectively, rounded up.
{{Class|Warlock}}s are unique in this regard, their spell slots are all of a uniform level, matching the highest spell slot available of a normal full spellcaster class until spell level 5, which is the highest level spell slot warlocks can have. They also simply gain a spell slot at class level 1,2, and 11.
When multiple classes with the Spellcasting feature are chosen for a character, the creature's total ESL is instead the summed ESL of every individual spellcasting class they have taken a level in, each rounded down.
== Concentration ==
==== Pact Magic ====
''Main page: [[Concentration]]''
Warlocks do not cast spells through the Spellcasting feature, but through their unique Pact Magic feature. Spell slots granted by Pact Magic are always of the highest level the Warlock can cast, and are replenished on a short rest. Spells cast using Pact Magic are always upcast at the highest possible level.
'''{{Concentration}}''' is another type of resource a spellcaster has. Certain spells require the caster to continuously put focus into the spell in order to maintain its effects, such spells are called '''{{Concentration}}''' spells, and this requirement will be clearly labeled with the '''{{Concentration}}''' tag in the spell's description. The caster may still do other actions while concentrating, but are at risk of losing said concentration under certain circumstances. If the caster loses Concentration, the spell ends prematurely. A caster can only concentrate on one spell at a time, said spell will be shown on top of/next to the caster's portrait.
To distinguish them from Spellcasting spell slots, Pact Magic spell slots have a unique colour: {{SpellSlot|1 Warlock|2|w=24}}
When the caster takes damage, they must make a Constitution [[Saving Throws|Saving Throw]] ({{D20}} + [[Constitution#Constitution Modifier Chart|Constitution Modifier]]) to maintain Concentration. The result must match or exceed a [[Difficulty Class|DC]] of 10 or half the number of damage they received, whichever is higher.
Spell slots gained from Pact Magic are calculated differently than those gained from Spellcasting. As such, levels taken in warlock are ignored when calculating ESL.
* Ways you can lose Concentration while maintaining Concentration Spells:
==== Other uses of spell slots ====
** Failing a Concentration Check by taking damage.
Some Wizard subclass features (such as [[Arcane Ward]] and [[Grim Harvest]]) and the Paladin's [[Divine Smite]] ability have varying effects depending on level of the spell or spell slot used to power them.
** Casting another Concentration Spell.
** Being affected by [[Condition]]s such as [[Condition#Downed|Downed]], [[Condition#Sleeping|Sleeping]], [[Rage]], etc.
** Voluntarily ending the concentration effect. (This is done by clicking the x button on the concentrated spell's icon on top of/next to the caster's portrait)
== Spellcasting Ability and Proficiency ==
=== Ritual spells ===
Every class, ''even non-spellcasters'', has an [[Ability Scores|ability]] specifically designated to represent their ability to cast spells. This ability would be that class's '''Spellcasting Ability''', the Ability Score Modifier of said '''Spellcasting Ability''' is directly added to the difficulty for which the spellcaster's targets face when trying to mitigate the effects of most spells from said spellcaster. This added difficulty-to-resist is more simply known as the spellcaster's '''Spellcasting Ability Modifier.'''
When a {{Icon|Ritual Spell Icon.png|24px}} ritual spell is cast outside of combat/turn-based mode, it does not consume spell slots and is effectively free to cast. Ritual spells consume spell slots as normal in combat/turn-based mode.
Non-spellcasters typically only cast spells by using magical items (which include scrolls), however, they are not considered '''Proficient''' spellcasters. Whereas actual Spellcasters are considered '''Proficient''' at spellcasting, whether with learned spells or magical items. '''Spellcasting Proficiency''' has similar function to '''Spellcasting Ability Modifier'''.
For more details, see the [[Saving Throw]] and [[Attack Roll]] pages for a comprehensive explanation of how the '''Spellcasting Ability Modifier''' and '''Spellcasting Proficiency''' is applied.
Each class uses a different [[Ability Modifier|Ability Score Modifier]] for spellcasting:<!-- Sorted by spellcaster status, and then alphabetically -->
* {{SmallIcon|Intelligence_Ability_Icon.png|link=Intelligence}} '''[[Intelligence]] (INT)''': {{Class|Wizard}}s, {{Class|Fighter}}s*<sup>†</sup>, and {{Class|Rogue}}s*<sup>†</sup>.

<div class="width:50%" style="padding:5px">
== Prepared Spells ==
'''Prepared Spells''' are Spells that must be prepared beforehand in order to be cast, this can only be done outside of combat. Spellcasters that primarily utilizes this type of spells are known as '''Prepared Spellcasters'''. This includes:
* {{Class|Cleric}}
* {{Class|Druid}}
* {{Class|Paladin}}
* {{Class|Wizard}}
These spellcasters will need to anticipate which spells would be useful in advance. In exchange, these classes will have access to every class-level-appropriate spell in their Spell List.
Uniquely, Wizards are prepared casters that can only choose a subset of eligible spells to be learnt on leveling up, but are allowed to learn more spells by transcribing scrolls.
The number of Prepared Spells each class can have at a time is equal to '''(Spellcasting Ability Modifier + Class Level) (Minimum of 1)'''
For this purpose a Paladin's class level is '''halved and rounded down'''.
</div>
<div class="width:50%" style="padding:5px">
== Known Spells ==
'''Known Spells''' are spells permanently memorized by a spellcaster, meaning these Spells are functionally '''Always Prepared'''. Spellcasters that primarily utilizes this type of spells are known as '''Spontaneous Spellcasters'''. This includes:
* {{Class|Arcane Trickster}}
* {{Class|Bard}}
* {{Class|Eldritch Knight}}
* {{Class|Ranger}}
* {{Class|Sorcerer}}
* {{Class|Warlock}}
These spellcasters will not need to worry about spell preparation. In exchange, they can only learn a subset of their class's Spell List.
Spontaneous Spellcasters have access to the '''Replacement Spell''' feature, which allows them to swap a known spell each time they level up.
Additionally, Spells granted by [[Character_Creation#Playable_Races|Races]] or by certain Subclasses (such as [[Cleric]] Domains) are considered "inherent" and is '''Always Prepared'''. This happens even if the character in question has a class that is normally is a Prepared Spellcaster.

* '''Cantrips''' are '''Spells''' that do not cost [[Spells#Spell Slots|Spell Slots]] to cast.
{{div col | style = column-width: 18em; list-style-type: none;}}
* '''Level 3 Spells''' are '''Spells''' that consume Level 3 [[Spells#Spell Slots|Spell Slots]] when cast.
Spells can be cast from scrolls that are bought, found or looted. Spells cast from scrolls cannot be [[Upcasting|upcast]] (cast with a higher level spell slot for additional benefits e.g. to affect more targets) or benefit from [[metamagic]]. Scrolls cannot be created (scribed from a wizard's spellbook). Wizards can learn spells from scrolls (scribe the spell from a scroll into their spellbook). See [[Wizard|Wizard/Spell scribing]].

Spells are magical effects that are created by creatures via spellcasting.[note 1] Spells are frequently cast to deal damage and provide healing, or to inflict conditions on the targets.
All classes are capable of casting spells with the help of scrolls and magic items, and classes with the Spellcasting or Pact Magic features – called spellcasters – have spell slots they can expend to cast spells they know, without the need for scrolls.
Spells are created from the Weave, the magical energies of the multiverse. They are conjured through experience, knowledge, or innate ability, or via the use of scrolls and magical items.
All spells have a level – a measure of its power and difficulty to cast. To cast a spell, the caster must usually expend a spell slot of sufficient level. Spells cast from scrolls do not consume spell slots when cast, nor do most spells granted by magic items.
Level 0 spells are called cantrips, and can always be cast at will, without expending a spell slot.
Every class – including those without the Spellcasting feature – has a designated ability known as their spellcasting ability, which represents their capacity to cast spells.[note 2]
When casting a spell, the spellcasting ability used depends on whether the spell was learned (first two points below) or cast from an item.
Spells learned from taking levels in a class will use that class' spellcasting ability modifier.
Spells learned from scribing a scroll into your Spellbook count as Wizard spells (because learning from scrolls is a Wizard feature) and thus use Intelligence.
Spells from other sources (including items, Illithid Powers that require a saving throw, and using scrolls directly from inventory) use the spellcasting ability of the class the creature most recently took a first level in.[note 3]
Each spell belongs to a school which defines its general purpose, and all spells have a range at which they can be cast, and a specified target or area of effect. A spell may have an instantaneous effect when cast (for example a magical attack), or a spell may have an effect which persists for a specified duration (measured in turns).
Most spells can be interrupted by Counterspell before they are cast, and most spells cannot be cast by Silenced creatures.
All spells have a casting time that determines whether it requires the caster to take an Action, a Bonus action, or a Reaction. Most spells require the caster to take an action.
Harmful spells which don't require an attack roll, such spells that target an area or a specific point in space – or that affect a target directly – often allow targeted creatures to attempt a save against the spell, potentially ignoring or reducing the spell's effect.
The Difficulty Class (DC) of these saves – called the spell save DC – is generally based on the caster's spellcasting DC:
Some harmful spells – typically those cast in the form of rays or as projectiles – require the caster to make an attack roll against the target's AC in order to determine if their spell attack is a hit or a miss.
The caster adds their spellcasting ability modifier, as well as their proficiency bonus, to the results of the attack roll:
Most spells with a duration require Concentration to maintain them. A caster may only maintain the effect of one concentration spell at a time. If concentration on a spell is broken, the spell's effects are ended immediately.

↑Some spells designate a specific spellcasting ability regardless of the class casting them. This is most commonly a result of spells obtained via racial features. Arcane Trickster Rogues and Eldritch Knight Fighters gain the Spellcasting feature as part of the subclass selected at Level 3.
↑A character who starts with 5 levels in Sorcerer will use Charisma for all of their sorcerer spells, as well as spells granted by equipment (e.g. the Firebolt cantrip granted by the Gold Wyrmling Staff) and spell scrolls. If this character at level 6 takes their first level in Wizard then their Wizard spells (including spell scrolls scribed into their Spellbook) will use Intelligence, their Sorcerer spells will continue to use Charisma, but spells granted from equipment and spell scrolls cast directly from inventory will now use Intelligence.
