An eldritch knight only gets 2 cantrips to start. This is very limiting. Is there a way to get more cantrips to increase the eldritch knight's utility and flexibility? What is the maximum number of cantrips possible for a character that is a level 4 eldritch knight?

Assuming a single class Eldritch Knight (EK) for base of 2 cantrips.

Start as a High Elf for +2 dex, +1 int, and any cantrip from the wizards list. This is more optimal for an EK than starting as a Tiefling.

At level 4 select the Magic Initiate feat to gain 2 cantrips and 1 first level spell.

For a total of 5 cantrips at level 4 plus a bonus spell from magic initiate.


Multi-classing, feats, and racial features will get you more cantrips.

Being a tiefling grants the cantrip thaumaturgy. On top of that, taking a level in other classes that grant cantrips or taking the magic initiate feat are the most efficient methods of gaining additional cantrips.

Max cantrips for a character level 4 with all levels in fighter

A tiefling taking the magic initiate feat at L4 would have an additional three cantrips for a total of five. They would get thaumaturgy from their racial feature and an additional two cantrips from the feat.

Classes granting cantrips at 1st level

Wizard, sorcerer, cleric, druid, bard, warlock all grant cantrips:

At 1st level, you know two cantrips of your choice from the [class] spell list


Some feats grant additional cantrips known: aberrant dragon mark, spell sniper, and magic initiate.

Racial Features

Some races have a feature that grants a cantrip. E.g. the Infernal Legacy trait of the tiefling:

You know the thaumaturgy cantrip.

Maximum cantrips innate to the character: 33

The following build uses a racial features, feats, and a ludicrous amount of multiclassing to maximize the number of cantrips known for a "level 4 eldritch knight." The build only gets two classes to level 4, thus only gets two feats.

\begin{array}{|l|l|l|} \hline \textbf{Class} & \textbf{Level} & \textbf{Cantrips} \\ \hline \text{bard} & \text{1} & \text{2} \\ \hline \text{cleric} & \text{1} & \text{2} \\ \hline \text{druid} & \text{1} & \text{2} \\ \hline \text{sorc} & \text{4} & \text{5} \\ \hline \text{wizard} & \text{2 illusion tradition} & \text{3+1} \\ \hline \text{warlock celestial} & \text{3 pact of the tome} & \text{4+3} \\ \hline \text{rogue} & \text{3 arcane trickster} & \text{0+3} \\ \hline \text{artificer} & \text{1} & \text{2} \\ \hline \text{fighter} & \text{4 eldritch knight} & \text{0+2} \\ \hline \\ \hline \textbf{total} & \text{20} & \text{29} \\ \hline \end{array}

\begin{array}{|l|l|} \hline \textbf{Feat or Feature} & \textbf{Cantrips} \\ \hline \text{Racial Feature e.g. Infernal Legacy} & \text{1} \\ \hline \text{Spell Sniper or Aberrant Dragon Mark feats} & \text{1} \\ \hline \text{Magic Initiate feat} & \text{2} \\ \hline \\ \hline \textbf{total} & \text{4} \\ \hline \end{array}

Grand total of 33 cantrips known at level 20.

Interesting honorary mention: Mizzium Apparatus

This is a wondrous item described in Guildmaster's Guide to Ravnica on page 179 that allows the wearer to attempt to cast cantrips on their class list despite not knowing them with a DC10 arcana check. Coupled with rogue's expertise and a decent int bonus, it would allow reasonably reliable casting any cantrip from the character's class lists.

  • \$\begingroup\$ Do the Ravnica backgrounds grant cantrips? \$\endgroup\$ Commented Apr 8, 2020 at 16:39
  • \$\begingroup\$ @Medix2 ooo... that's a good point. I didn't think to check there. Also, eberron artificer might get cantrips. I haven't used that source book enough yet. \$\endgroup\$

    \$\begingroup\$ @Medix2 Flipping through it appears the backgrounds add cantrips to your spell list, but don't grant them to you directly. Interestingly there is an item that lets the user cast cantrips they don't know, but are on their class list. \$\endgroup\$

    \$\begingroup\$ Don't forget, High Elves get any Wizard cantrip. Also, why did you mention multiclassing with Magic Initiate? In regards to number of cantrips known, it's strictly better than Spell Sniper. \$\endgroup\$ Commented Apr 8, 2020 at 18:20
