[Top 5] D&D: Best Warlock Multiclass

D&D: Best Warlock Multiclass
The cover of the Player's Handbook by Wizards of the Coast

An unknown, shadowy being wreathed in tentacles and teeth. A devilish god cracking a fire-strung whip. A kind smile from the Divine, guiding your hands to heal your allies. The Warlock class gives versatile abilities that mix magic and combat into one and is open to a lot of mix-and-match with other classes. Here are five great multiclasses for the Warlock class in D&D 


Sorcerers: For when you don't want to work for your magic

This one is pretty low on the list because it’s one of the most common builds. So common, in fact, that many DMs ban it altogether. The Sorcerer multiclass gives you access to cast an insane amount of Eldritch Blasts thanks to the metamagic, to the bane of every DM. Even better, with your Eldritch Invocations, you can add bonuses to your blasts to give them an even better punch. Not the most creative build, but a good one nonetheless, and pretty equal in terms of levels of Warlock and Sorcerer, too.

Why Warlock/Sorcerer is Great

  • Warlock gives you, at level 9, the Agonizing Blast, Repelling Blast, Eldritch Spear, and Lance of Lethargy invocations
  • You also have access to 5th level warlock spell slots
  • Sorcerer gives you metamagic, which allows you to cast Quickened spells, meaning that you can cast eldritch blast twice in one turn.
  • With all those invocations, with your beginning hit you’re casting six beams in one turn, knocking the enemy back 10 feet, then reducing its speed by 10

4. Bardlock

Charm your patron with some sick beats

This one is a little of a no-brainer. You can’t go wrong with Bard, as they’re probably one of the most varied classes on the list. Since Charisma is used in both Warlock and Bard, your spells won’t suffer because of a divergence in ability score allocation, and Bard spells can add some much-needed utility or support to your Warlock. If you’re more of a Combatlock than a long-distance caster, the College of Swords subclass for Bard could help you out even more, as well! 

Why Warlock/Bard is Great

  • Both Warlock and Bard are Charisma classes
  • More access to utility spells
  • Add bonus to combat ability by subclassing into College of Swords

3. Warlock/barbarian

I would like to rage.

Now we’re getting interesting! Most people wouldn’t think of multiclassing into the brutish, beefy barbarian, but it has a surprising amount of upsides. For starters, though your Rage makes it impossible to cast spells, it says nothing about Eldritch Invocations. That means anything from teleportation, to added damage, or even invisibility, and a Barbarian with those bonuses can be deadly. Not to mention the added HP and AC from Unarmored Defense, keeping you in the game long enough to slice your enemies with an eldritch burst.

Why Warlock/Barbarian is Great

  • While in rage, Eldritch Invocations are still game
  • Unarmored defense, which could improve AC a great deal
  • Allows versatility to both cast spells at a distance

2. Fighterlock


Similar to the Barbarian, the Fighter offers increased combat prowess for your Warlock, but at an even greater level. This is more of a Fighter/Warlock than a Warlock/Fighter, as dipping into Warlock while Fighter is your main class gives you access to greater weapons and armor proficiencies. The important part is to make sure you don’t choose Hexblade for your patron; the purpose of this build is to add the defense of a Fighter to your otherwise combat-less caster. It gives a nice flavor to your Warlock to be able to hack and slash while being attached to a different deity, and the Fighter’s Fighting Styles and other special abilities lead to even greater customization.

Why Warlock/Fighter is Great

  • It’s better to take Fighter first before dipping into Warlock for the Con saving throw proficiencies and extra armor/weapon proficiencies
  • With a patron other than Hexblade, you can get more defensive abilities to aid your party
  • The added Action Surge and Fighting Styles can help you diversify your fighter even more
  • With a few Fighter classes, you get added hit points for a more durable character

1. Warlock/Paladin

Holy... or eldritch?

So, the Paladin build. It gives you a Fighting Style and even more spells to cast, with added spell slots for more opportunities to throw out some magic. Sounds good, right? Well, that isn’t even close to what this build is capable of doing. For starters, depending on the spell, you can use Warlock slots for Paladin spells or Paladin slots for Warlock spells. This gives you major flexibility in how you cast. But y’know what else you can cast with Warlock spell slots? Smites. That’s right, not only can you use your Divine Smite with your Paladin slots, but you have even more room to deal massive damage on each of your hits, switching from your Paladin slots right over to your max-level Warlocks. This can be devastating to almost every fight you encounter, making you an unstoppable Eldritch force to make every DM tremble. 

Why Warlock/Paladin is Great

  • Paladin abilities grant extra Divine Sense, a Fighting Style, and more spells
  • Extra armor proficiencies are also available, leading to more defense
  • Smites are fantastic with this build, because, get this—you can use either your Paladin or Warlock slots for Divine Smites. That means, at your max Warlock spell slot level (5th), you get up to four fifth level Divine Smits to land on your hits
  • The above rule also applies to the other spells in the Paladin spell list, meaning you can have even more max-level spells as long as they’re able to scale
