Out of all the spellcasters in the Dungeons & Dragons universe, the Warlock is the most versatile, which is one of the reasons it's so popular among players. In Dungeons & Dragons, Warlocks are unique casters that allow for a lot of customization and options for different builds. It’s possible to make a warlock as a melee bruiser with a few game-changing spells, a hard-hitting sniper with powerful cantrips, or anywhere in between. Since there are so many potential ways to play a Warlock, there are also plenty of feats that can synergize with any build you make.

For those who don’t know, feats are special abilities that can be taken in place of ability score improvements at certain levels. There’s no one best feat for a Warlock since there are so many different types of Warlocks to play, but here are some good choices.

Updated on July 15, 2021, by Kristy Ambrose: The tradition of the Warlock as a highly customizable character that can fit in almost any role, and that doesn't just mean as their role in the party. A Warlock can be any moral alignment, although this might depend on their backstory and pact, and almost any race can make an ideal Warlock. Knowing the best Feats to choose from during the initial stages is still an essential part of early character creation, so we've added a few more of the best Warlock Feats in D&D 5e to our list.

Polearm Master

  • Ideal Otherworldly Patron: The Hexblade
  • Useful Ability: Allows players to make attacks as a bonus action, grants opportunity attacks whenever enemies enter your melee range
  • Ideal Combination: Great Weapon Master Feat

Let’s start with a good feat for any melee Warlock build, especially those with the Hexblade Pact and/or the Pact of the Blade Pact Boon, the Polearm Master. As a melee Warlock, you’ll want to be taking as many attacks as you can, so the extra bonus and opportunity attacks fit perfectly.

You’ll want to use a glaive or halberd for this feat, because both have the reachability, meaning you basically have a 10 foot “do not enter” zone around you. Since both of these are heavy weapons, this feat can combo nicely with the Great Weapon Master Feat, which will sometimes allow you to make a regular melee attack as a bonus action, as well as sacrifice some accuracy for extra damage.

Spell Sniper

  • Ideal Otherworldly Patron: The Fathomless or The Fiend
  • Useful Ability: Makes Eldritch Blast even more reliable and removes the need for Eldritch Spear.
  • Ideal Combination: Resilience or War Caster Feats

On the other hand, maybe you want to do build on your Eldritch blast powers, focusing your Eldritch Invocations into improving your ubiquitous cantrip. In that case, Spell Sniper might be the feat for you. As the name suggests, the feat doubles the range of spells that require an attack roll, bringing your Eldritch Blast range up to an impressive 240 feet (or 600 feet with the right invocations).

This kind of build works best with a Warlock intended to be a Damage dealer, thus the connection to Pacts that correspond with that party role. Any build intended to do spell damage also blends well with Spell Sniper.

Crossbow Expert

  • Source: D&D Player's Handbook
  • Ideal Otherworldly Patron: Hexblade
  • Useful Ability: The loading property of crossbows doesn't matter, no Disadvantage for being in contact with a creature when you shoot.
  • Ideal Combination: Elven Accuracy Feat

As a Warlock with a handy long-range damaging cantrip at your fingertips, you likely won’t ever pick up a crossbow, but the Crossbow Expert feat can still be a good investment for an Eldritch Blast-focused Warlock.

Spell Sniper is a nice compliment to this, but not all enemies are considerate enough to stay exactly 600 feet away from you. Crossbow Expert means that you can attack enemies that are right in your face with Eldritch Blast without disadvantage, which is perfect if you chose a full range build.

Fey Touched

  • Ideal Otherworldly Patron: The Archfey
  • Useful Ability: +1 bonus to Intelligence, Wisdom, or Charisma, learn Misty Step and one 1st-level spell from the Divination or Enchantment school.
  • Ideal Combination: Hex spell

Extra spells are always a bonus, and since the Warlock has a reputation for fewer choices in that regard in comparison to Sorcerers or Wizards, this choice of Feat is a good choice for any of the best Warlock builds. The Archfey is a natural choice for a number of reasons, one that could be related to the character's ancestry or upbringing. Characters that are connected to the Fey are often high in Charisma and Dexterity, important skills for Warlocks, making the choice feel even more organic.

Elemental Adept

  • Source: D&D Player's Handbook
  • Ideal Otherworldly Patron: The Fiend
  • Useful Ability: Spells ignore resistance to a damage type, such as acid, cold, fire, lightning, or thunder, and any 1 damage is counted as 2.
  • Ideal Combination: Spell Sniper Feat

One of the most popular Warlock Pacts is The Fiend, which allows you to make a deal with a devil in exchange for a variety of fire-and-brimstone-related abilities. The main weakness of this Pact is that sometimes you come across an enemy that is resistant to fire, in which case you are out of luck. Unless of course, you take the Elemental Adept feat. You will want to set it to fire damage, which allows you not only to ignore fire resistance but also will help you flub your fire damage rolls less.

War Caster

  • Source: D&D Player's Handbook
  • Ideal Otherworldly Patron: The Hexblade or The Celestial
  • Useful Ability: Maintain Concentration when taking damage
  • Ideal Combination: Elven Accuracy Feat

This Feat isn’t necessarily warlock-specific, since it is beneficial to almost any spellcasting class, but they do have the advantage of being helpful in pretty much any Warlock build. War Caster will help Warlocks who like crowd control to maintain their concentrations, be in melee combat to cast while fully armed, or use cantrips as part of their wide variety of spells for opportunity attacks.

Plus, since Warlocks have more limited spell slots than other casters, the ability to make concentration spells last as long as possible without breaking lets you get the most use out of your kit. Add the Elven Accuracy Feat, which also covers spellcasting, to make this even more deadly.

Flames of Phlegethos

  • Ideal Otherworldly Patron: The Fiend
  • Useful Ability: Deal fire damage in an area to enemies that hit you with melee attacks whenever you cast a fire spell.
  • Ideal Combination: Spell Sniper Feat

Some race-specific Feats can be useful and plenty of Warlocks choose this ascendancy. Flames of Phlegethos is a good feat for Tieflings who have a pact with The Fiend. It doesn’t stack well with Elemental Adept, since it lets you reroll 1s while Elemental Adept bumps them up to 2s, so you might want to pick one or the other. It does give +1 to Charisma, so if you need one extra to get your spellcasting bonus higher, it might be the better choice.

Elven Accuracy

  • Ideal Otherworldly Patron: The Archfey
  • Useful Ability: Reroll one attack roll if you have Advantage, +1 bonus in Dexterity, Intelligence, Wisdom, or Charisma.
  • Ideal Combination: Crossbow Expert Feat

Elven Accuracy is another Feat that gives a boost to Charisma and is good for races that already have the stats to make good Warlocks. Any race of Elven descent has access to Elven Accuracy, and it affects both spell and weapon damage. Since Warlocks use Charisma to cast, it will give a reroll on any attacks that you already have Advantage, meaning it can be useful if you have a party that is good at setting that up for you.
