Pact Magic

Your arcane research and your patron’s magic have given you spellcasting ability.

Cantrips

You have two cantrips of your choice from the warlock spell list. At higher levels, you learn additional warlock cantrips of your choice, as indicated by the Warlock table’s Cantrips Known column.

Spell Slots

The Warlock table shows how many spell slots you have to cast your warlock spells from 1st to 5th level. The table also shows the level of each slot; all of your spell slots are the same level. To cast one of your warlock spells of the first or higher level, you must use a spell slot. When you finish a short or long rest, you regain all of your expended spell slots.

For example, at fifth level, you have two 3rd-level spell slots. To cast the 1st-level spell witch bolt, you must use one of those slots and cast it as a 3rd-level spell.

Spells known at the first level and higher

At 1rst level, you can choose two 1st-level spells from the warlock spell list.

When you learn more warlock spells of 1st level or higher, the Spells Known column of the Warlock table displays them. A spell you choose must have a level no higher than that indicated in the table’s Slot Level column for your level. When you reach sixth level, for example, you learn a new warlock spell that can be of the first, second, or third level.

Furthermore, when you level up in this class, you can replace one of your warlock spells with another from the warlock spell list, which must be of the same level as your spell slots.

Spellcasting Ability

Charisma is your spellcasting ability for warlock spells, so use it whenever a spell mentions your spellcasting ability. In addition, you use your Charisma modifier to determine the saving throw DC for a warlock spell you cast and to make an attack roll with one.

Spell save DC = 8 + proficiency bonus + Charisma modifier.
Spell attack modifier equals your proficiency bonus plus your Charisma modifier.

Spellcasting Focus

You can use an arcane focus to cast warlock spells.

Otherworldly Patron

At the 1st level, you have made an agreement with an otherworldly being chosen from the list of available patrons. Your choice grants you features at the first level, as well as at the sixth, tenth, and fourteenth levels.

Eldritch Invocations

In your research into occult lore, you discovered eldritch invocations, fragments of forbidden knowledge that endow you with a permanent magical ability.

At the 2nd level, you gain two eldritch invocations of your choosing. The Optional Features page contains a list of all available options. When you reach certain warlock levels, you gain access to additional invocations of your choice, as indicated in the Warlock table’s Invocations Known column.

Furthermore, as you advance in this class, you can replace one of the invocations you know with another invocation that is available at that level.

If an eldritch invocation requires prerequisites, you must meet them before learning it. You can learn the invocation while meeting the prerequisites. A level prerequisite indicates your level in this class.

Pact Boon

At the third level, your otherworldly patron rewards you with a gift for your loyal service. You receive one of the following features of your choosing.

1. Pact of the Blade

You can use your action to make a pact weapon with your empty hand. You can change the form of this melee weapon each time you create it. You are skilled with it when you use it. This weapon is classified as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Your pact weapon vanishes if it is more than 5 feet away from you for 1 minute or longer. It will also disappear if you use this feature again, dismiss the weapon (no action required), or die.

You can turn one magic weapon into your pact weapon by performing a special ritual while holding it. The ritual is performed over a one-hour period, which can be completed during a brief rest. You can then dismiss the weapon, which disappears into an extradimensional space and reappears whenever you create a pact weapon after that. This method cannot be used to affect an artifact or a sentient weapon. If you die, perform the 1-hour ritual on a different weapon, or break your bond with the weapon, it no longer serves as your pact weapon. If you are in extradimensional space, the weapon appears at your feet when the bond is broken.

2. Pact of the Chain

You learn the find familiar spell and can use it in a ritual. The spell does not count against your total number of spells known.

When you cast the spell, you can select one of your familiar’s normal forms or one of the special forms listed below: imp, pseudodragon, quasit, or sprite.

Furthermore, when you use the Attack action, you can skip one of your own attacks and allow your familiar to use its reaction to launch one of its own.

3. Pact of the Talisman

Your patron gives you an amulet, which is a talisman that can help the wearer in times of great need. When the wearer fails an ability check, they can add a d4 to the roll, potentially resulting in a success. This benefit can be used as many times as your proficiency bonus, and all expended uses are restored after a long rest.

If you lose the talisman, you can request a replacement from your patron by performing a one-hour ceremony. This ceremony can be performed during a short or long rest period and destroys the previous amulet. When you die, the talisman turns into ash.

4. Pact of the Tome

Your patron gives you a grimoire known as the Book of Shadows. When you gain this feature, select three cantrips from any class’s spell list. The cantrips do not have to come from the same spell list. You can cast those cantrips whenever you want while carrying the book. They do not count against your total number of known cantrips. Any cantrip you cast using this feature is considered a warlock cantrip by you. If you lose your Book of Shadows, you can request a replacement from your patron by performing a one-hour ceremony. This ceremony can take place during a short or long rest, and it destroys the previous book. When you die, the book turns into ash.

Ability Score Improvement

When you reach the 4th level, you can choose to increase one ability score by two or two ability scores by one. This feature cannot be used to increase an ability score above 20.

If your DM permits the use of feats, you may instead take one.

Eldritch Versatility

is an optional feature for fourth-level warlocks.

When you reach a level in this class that grants the Ability Score Improvement feature, you can do one of the following, which represents a shift in your occult studies.

Replace one cantrip learned through this class’s Pact Magic feature with another from the warlock spell list.
Replace the option you selected for the Pact Boon feature with one of its other options.
If you are 12th level or higher, replace one of your Mystic Arcanum spells with another warlock spell of the same level.
If this change makes you ineligible for any of your Eldritch Invocations, you must replace them with invocations for which you are eligible.

Otherworldly Patron Feature

At the 6th level, you gain a feature granted by your Otherworldly Patron.

Ability Score Improvement

When you reach the 8th level, you can choose to increase one ability score by two or two ability scores by one. This feature cannot be used to increase an ability score above 20.

At higher levels, you gain more warlock spells of your choosing that can be cast in this manner: one 7th-level spell at 13th level, one 8th-level spell at 15th level, and one 9th-level spell at 17th level. After a long rest, you regain full use of your Mystic Arcanum.
