Warlocks are spellcasters who have made a pact with a powerful entity to gain their powers. Wielding many powerful spells and abilities, they make for very helpful companions.

Best race for Warlock

1. Tiefling - each subrace innately knows a different, useful spell.
2. Drow - dark elves at level 3 and level 5 gain access to useful spells: Faerie Fire and Darkness. They also have Darkvision.

Ability Points

When distributing stat points for a Warlock, prioritize Charisma. Your secondary stats should be:

1. Constitution - it will grant some extra hit points and help with passing concentration checks.
2. Dexterity - high Dex will increase your Armor Class when wearing light armor.

Best background for Warlock

Among all available backgrounds, Warlocks can especially benefit from:

1. Charlatan - grants proficiency in Deception and Sleight of Hand, nicely complementing a high Dexterity build.
2. Criminal - just as useful as Charlatan, though granting Stealth instead of Sleight of Hand.

Eldritch Invocations

The Warlock's class ability, available from Level 2 onwards. They gain bonuses thanks to the pact they made. Among available invocations we especially recommend:

1. Agonizing Blast - Damage dealt by the Eldritch Blast cantrip is increased by the Warlock's Charisma modifier.
2. Repelling Blast - creatures hit with Eldritch Blast are pushed back by 3 meters. Nicely synergises with the previous invocation.
3. Mask of Many Faces - lets you cast Disguise Self without using a spell slot.
4. Devil's Sight - lets the Warlock see up to 24 meters in regular or magical darkness. Especially useful to races without innate Darkvision, such as Humans.

Pact boon

At Level 3, the Warlock receives a boon from their benefactor, granting additional abilities.

1. Pact of the Chain - the Warlock gains the ability to summon a Familiar, which can take one of several forms: an imp, a quasit or an animal. Each has different traits and can help you in combat. The familiar's form can be freely modified.
2. Pact of the Blade - the Warlock can summon a chosen melee weapon as an action. It can be drawn or hidden, but must be equipped by the Warlock. The Warlock is always proficient in using it.
3. Pact of the Tome - the Warlock receives a special grimoire from their patron. It lets them learn three Cantrips from any class. Having this book, the Warlock can cast these cantrips at will.

Best spells

The Warlock has few spell slots, though it's compensated by how these slots are always the highest available level. Additionally, Warlocks restore their spell slots on short rests, while most other casters require long rests.

Here are a few interesting cantrips and spells. You'll find the full list on the Best Warlock spells page in our guide.

Cantrips:

1. Eldritch Blast - the Warlock's signature cantrip, dealing a huge 1d10 damage. The damage scales as you level up, while the Agonizing Blast invocation makes it an extremely formidable attack.
2. Chill Touch - 1d8 damage and an additional effect preventing your foes from restoring health.
3. Minor Illusion - creates an illusory object to distract nearby creatures.

Spells:

1. Armor of Agathys - the Warlock gains +5 AC and deals 5 cold damage to each enemy who attacks them in melee.
2. Hex - the target receives 1d6 damage, takes bonus damage on subsequent attacks and has disadvantage on selected ability rolls.
3. Arms of Hadar - the target takes 2d6 necrotic damage and can no longer use reactions.
4. Expeditious Retreat - the caster can Dash as a bonus action.
5. Protection from Evil and Good - protects the target from fiends, fey, celestials, aberrations and elementals. These types of enemies can no longer charm, frighten or possess the target. They also have disadvantage on attacks against the target.
6. Witch Bolt - the target takes 1d12 damage. Every turn, the caster can remotely trigger the arc connecting them to the target to deal 1d12 damage again.
7. Misty Step - a Level 2 spell which lets the caster teleport to a chosen, visible location.
8. Hold Person - paralyzes a humanoid target, preventing them from moving or taking actions.
9. Hunger of Hadar - a Level 3 spell which creates a nightmarish sphere. Creatures inside the sphere take 2d6 damage. Ending a turn inside the sphere deals another 2d6 damage. The sphere counts as difficult terrain and all creatures within are blinded until they leave it.

Best subclass for Warlock

Warlock Subclasses are defined by the being they've made a pact with. Each mighty patron grants other abilities and exclusive spells.

The Fiend - the character has made a pact with an evil Fiend from another plane of existence. The Dark One's Blessing ability lets the Warlock restore hit points, equal to their Charisma modifier, whenever they reduce an enemy to 0 HP. This subclass' exclusive spells include:

1. Burning Hands - deals 3d6 fire damage.
2. Command - forces the target to stop, get closer, run away, go prone or drop their weapon.

The Great Old One - the character has made a pact with an ancient eldritch being. The Mortal Reminder ability frightens nearby enemies for a turn whenever the Warlock crits. This subclass' exclusive spells include:

1. Dissonant Whispers - frightens the target for 2 turns and deals 3d6 damage.
2. Phantasmal Force - a Level 2 spell which creates an illusion in the target's mind, dealing 1d6 damage every turn for 10 turns.

Archfey - the character has made a pact with a powerful Fey, gaining abilities revolving around crowd control and status ailments. Fey Presence is an action forcing nearby creatures to make a Wisdom saving throw. If failed, the creature is charmed or frightened. Available later on, Misty Escape lets the Warlock become invisible after being hit and cast the Misty Step spell. This subclass' exclusive spells include:

1. Faerie Fire - reveals hidden enemies and grants advantage on attacks against affected foes.
2. Phantasmal Force - the target's mind has an illusion implanted in it, dealing 1d6 physical damage each turn (spell lasts for up to 10 turns). When the affected target receives damage from a different source, the Phantasmal Force damage type also changes. Similarly to the previous spell, it requires maintaining concentration.
