Within the realm of Dungeons & Dragons, battles are often fought with no lack of martial prowess or arcane wonder. While most adventurers tread separate paths of magic or physical feats, however, the Eldritch Knight wields with great skill and harmony.
With a limited yet potent selection of spells, the Eldritch Knight unlocks hidden potential in the fighter’s already-versatile arsenal. In the heat of battle, they can often be found safeguarding their allies while casting upon foes with great destructive force. If you can’t choose between playing a caster or a martial, the Eldritch Knight is an excellent way that you can wield both sword and spell in captivating synergy.
Eldritch Knight Features Overview
The archetypal Eldritch Knight combines the martial mastery common to all fighters with a careful study of magic.
Spellcasting |
|

Spellcasting is, obviously, the Eldritch Knight’s bread and butter. This is a complicated feature that stands uniquely different from the other spellcasters.
The Eldritch Knight’s Spellcasting Table is as follows, and details exactly how many cantrips, spells and spell slots you get at each level.

Cantrips |
|
---|
Firstly, you get to pick any two cantrips from the Wizard spell list—which is massive. Still, what works for a squishy caster in the backline won’t necessarily work for you and your trusty blade.
Suggestions on which spells work best for the Eldritch Knight can be found in the next section.
Spellcasting Ability |
Spell Slots
Spells Known of first Level and Higher
|
---|
The spell slots of the Eldritch Knight work much like normal—coming back on a long rest, like that of most casters’.
At third level, your Eldritch Knight gets their subclass, unlocking access to three spells right off the bat. Out of these, only one can be from any school of magic, while the other two must be chosen from the Abjuration or Evocation schools.
At the eighth, 14th, and 20th levels, you will again be able to pick one spell from any school of magic. All other spells gained outside these specific levels must still come exclusively from the Abjuration or Evocation schools of magic.
It should be clear by now that the vast majority of your spells will need to be either Abjuration or Evocation, meaning that when you get to pick spells that aren’t, you should do so carefully.
Spellcasting Ability |
|
---|
Interestingly enough, Intelligence—a stat that not many fighters tend to focus on—is your spellcasting ability. This means that your Eldritch Knight will be significantly more multi-attribute dependent than other fighters of different subclasses.
The build that this guide suggests doesn’t require you to have an overwhelmingly high Intelligence modifier to deal damage, but it will still affect some saving-throw spells, meaning that Intelligence probably shouldn’t be your dumpstat here.
Weapon Bond |
|
---|
Essentially, this lets you summon your weapon back to you whenever you want, and you can’t ever get it stolen out of your hand.
This is some good flavor, but it probably won’t see too much use in the standard campaign—unless it’s in an urban setting where your party has to attend lots of formal events unarmed, for example. Still, it does open the opportunity to throw your weapon and call it back into your hand, which is pretty cool.
There is no definition of the weight, size or nature of the weapon in this feature, meaning that you could technically bond with and teleport some pretty outlandish «weapons». Be sure to check with your DM first, however, to make sure that it’s the right table for shenanigans like that.
War Magic |
|
---|
Don’t be fooled by the apparent loss of a weapon attack with this feature. When combined with cantrips like Booming Blade or Green Flame Blade, it unlocks tactical advantages and unique battle strategies, sometimes easily surpassing the damage from the extra attack of other fighter subclasses. This is great, and can skyrocket your damage, as well as on-field utility.
Eldritch Strike |
|
---|
One of the weaknesses of the Eldritch Knight is their lower spell-save DCs, as Intelligence likely won’t be your highest score. This grants you, essentially, a free disadvantage that automatically gets imposed on any enemy you hit—and, hopefully, you’re hitting a lot of them by tenth level. This can also lead to tons of interesting combos involving AOE saving-throw spells, Action Surge, and your four attacks over two rounds.
Arcane Charge |
|
---|
This feature offers significant mobility, granting you the ability to position yourself strategically. Whether it’s getting out of harm’s way to unleash a powerful area-of-effect spell or closing in on a vulnerable target in the backline, this feature provides invaluable options for a melee fighter.
Improved War Magic |
|
---|
More attacks, more spells, more combos, more damage—there’s nothing not to like about this great feature. This also synergizes with the weapon-attack-imposed disadvantage with Eldritch Strike, making your next spell even easier to hit.

Recommended Spells
To go over each spell is not within the scope of this guide, unfortunately—but here is a general line of reasoning that you should consider when choosing spells for Eldritch Knight.
As an Eldritch Knight, your spell selection is crucial due to the limited options outside of Abjuration and Evocation schools.
With only four spells in your arsenal from levels 3 to 20 that can be outside those two schools, choose wisely to make the most impact. You may want to focus on heavy-hitting damage, survival, and combat utility spells to be effective—leaving exploration utility spells like identify, air bubble, detect magic, and comprehend languages to other spellcasters with more versatility.
Below are a few recommended spells to consider, but remember to tailor your choices to suit your playstyle and party needs.

Best Ability Scores For Eldritch Knight Fighters
As mentioned before, Eldritch Knights are quite Multi-Attribute Dependent. The ability scores that they are most dependent on are:
Strength |
|
Constitution |
|
Intelligence |
|
On the other hand, ability scores that won’t do much for an Eldritch Knight are:
Dexterity |
|
Wisdom |
|
Charisma |
|
This section outlines an optimal approach to building a Monk’s ability scores for peak performance, but remember, it’s just a guide! Feel free to diverge from it. Designing a character with imperfections or unique quirks can often be more fun and rewarding.
Best Species For Eldritch Knight Fighters
If your Dungeon Master doesn’t use Custom Lineages at your table (which allows you to choose your own ability scores), consider a Species that boosts both your Intelligence and Strength/Dexterity:
Species |
Benefit |
---|---|
Duergar |
Great innate spells complement the fighter’s abilities. Dwarven Resilience and Psionic Fortitude provide excellent frontliner support. |
Goliath |
Custom-made for a strength-based fighter, with features that greatly enhance durability and strength-based abilities. |
Half-Orc |
Savage Attacks and Relentless Endurance make for a resilient and hard-hitting fighter. |
Elf (Shadar-Kai) |
Ability to teleport provides excellent mobility, and damage resistance benefits frontliners. |
Human (Variant) |
Versatile Ability Score Increases, and the additional starting Feat is always fantastic to have. |
Shifter (Longtooth / Beasthide) |
Additional HP/AC and additional damage respectively, both advantageous for an Eldritch Knight. |
However, if your Dungeon Master allows for Custom Lineage, a lot of other options become much more viable:
Species |
Benefit |
---|---|
Dwarf (Mountain) |
Two +2 ability score increases are excellent for Fighters, allowing room for more feats. . |
Gnome (Forest) |
Extra Intelligence, along with Gnome Cunning granting advantage on saving throws, boosts your spellcasting and resilience. |
Elf (High) |
Bonus wizard cantrip using Intelligence modifier adds versatility to spell options. Trance and Fey Ancestry provide strong advantages. |
Hobgoblin |
«Fortune of the Many» provides insurance against tough saving throws, complementing the Fighter’s abilities, and «Help» action can aid allies in combat, making you a valuable support on the battlefield. |
Kobold |
Easy access to Advantage from «Pack Tactics» enhances accuracy, while «Draconic Sorcery» adds to the Eldritch Knight’s spellcasting versatility |
Githyanki |
Extra proficiency in a tool or skill adds versatility, and free racial spells with Intelligence casting are great options for a magical Fighter. |

Remember that your fighter will get vastly more Ability Score Increases (and thereby, Feats) than other classes!
Feat |
Benefit |
---|---|
Elemental Adept |
If multiple damage spells of the same elemental type are taken—which is likely for a frontliner—this feat greatly boosts damage. |

Intelligence increase, free Misty Step, and access to two extra spells, expanding mobility and casting options. |
Great Weapon Master |
Great damage increase when using two-handed weapons, boosting martial prowess. |
