Elves cannot be magically put to sleep, according to their Fey Ancestry trait.

The catnap spell (Xanathar's Guide to Everything, p. 151) can make up to three willing creatures fall unconscious (and get the benefit of a short rest after the 10-minute duration).

Can elves be affected by the catnap spell?

RAW - Yes, catnap can affect elves

Catnap is a bit deceptively named because, despite the name and the fact that one of its effects mimics a short rest, Catnap does not actually technically put creatures to sleep. And this is not the only example of a spell/ability confusingly named.1

The important thing to realize about this is that the names of spells/abilities have no mechanical meaning. Only the spell effect description describes how the spell works.

You make a calming gesture, and up to three willing creatures [...] fall unconscious for the spell’s duration.

Nowhere in the spell does it say anything about putting creatures to sleep, it only imposes the unconscious condition on them.2

And, since elves are not immune to the unconscious condition, they are affected by the spell like anybody else is.

Rules as Intended

Jeremy Crawford has confirmed this interpretation is as intended:

Q: My group is discussing the Catnap spell; are elves unable to be affected by it, even willingly?

A: Elves aren't immune to the unconscious condition.

Q: But they can't be put to sleep by magic. Is the effect of the catnap spell not magic or not sleep?

A: Nowhere does the catnap spell say it puts you to sleep.

1 - A few examples: Sacred flame does not do fire damage. Chill touch does not do cold damage and is also not a touch spell. Daylight does not actually create sunlight. Detect good and evil does not actually detect alignment.

2 - Compare this to sleep which says:

This spell sends creatures into a magical slumber.

    \$\begingroup\$ To be fair, with all the nitpicking of meaning inherent to D&D one might argue that 'sleep' and 'slumber' are not the same, and that Elves can be put into a slumber, but that calling it 'sleep' instead would make them immune to it. Just saying. After all, Sleep and Slumber are different words, and only one has a Game Term meaning and the other relies on Dictionary meanings. And there are other instances where synonymous words are treated differently in D&D. \$\endgroup\$

    \$\begingroup\$ @markto Neither sleep nor slumber is a in-game defined term. Both are to be used in their normal English meanings, and are thus synonymous \$\endgroup\$ Nov 12, 2018 at 16:02

Yes, but your DM might disagree.

Catnap doesn't actually say 'sleep' or 'slumber' or any similar word in the spell effect, so there's no reason an elf would be immune to the unconsciousness it causes.

Your DM might decide to disagree, based on the name of the spell, but this is probably one of those cases where the effects at the table are more important than the strictest reading of the rules. It's good for the party to be able to all reset their abilities at the same time, and bad to exclude one player from a beneficial effect just because of their species choice.

Or to put it another way, there's no harm in letting the elf take a short rest quickly, and there is harm in making the player feel like they're going to miss out, so it's better to say yes.


Yes. As the top answer notes, RAW, since catnap does not mention "sleep" or "slumber", only "Unconscious[ness]", Elves are not immune. In addition, it would not help the story for one party member to be unable to rest when others are able merely because of race.

However, it would help the story if there were something unique here to make the spell/race interaction interesting. And that's entirely possible. The spell description says:

The spell ends on a target early if it takes damage or someone uses an action to shake or slap it awake.

As a DM, my ruling would be that, while the spell put most targets to sleep, such that they could be shaken or slapped awake with a single action, it makes elves unconscious, such that waking them up is more laborious. The mechanical effects of that are unclear, but one simple possibility would be that the elf would be groggy (under the same effects as the slow spell) until they took damage. They could prick themselves for 1 damage to wake up fully.

This would probably come up no more than once in an entire campaign, so it would just be another interesting minor obstacle to overcome, not a punishing disadvantage. And I'd probably have the enemies or situation where it came up be relatively easy, so that it would be more a source of humorous roleplay than a serious issue or threat.


Sleep is a 1st level enchantment spell (magic) that causes an unconscious condition (sleep)

Sleep does state:

“... the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake.”

Catnap is a 3rd level enchantment spell (magic) that causes an unconscious condition (“unconscious”)

Catnap does state:

The spell ends on a target early if it takes damage or someone uses an action to shake or slap it awake.

awake by English definition is the opposite of sleep

Important note:


  • Blinded - Charmed - Deafened - Frightened - Grappled
  • Incapacitated - Invisible - Paralyzed - Petrified
  • Poisoned - Prone - Restrained - Stunned - Unconscious

It comes down to lack of cohesion with core vs explanation terminology.

The term sleep is one of the ways to acquire the unconscious condition, which is the rules mechanic. Same as being knocked out, instead of killed, when you hit 0 hit points.

So because Catnap doesn’t use the term sleep or slumber in the description, that somehow it’s different. Even though the title refers to a sleep terminology.

Fey Ancestry - ... magic can’t put you to sleep.

Trance - Elves don’t need to sleep

Elves can sleep, they just physically don’t have to.

I would rule, that the spell specifies willing and elves can sleep, that it can effect them. When it comes to magically forcing an elf to sleep, is what this racial trait is intended.

Not really well thought positive benefit as a modified sleep spell, but it is a weak technicality.

    \$\begingroup\$ FWIW, unconscious is a "condition" (see Appendix A) and "sleep" is one of a number of ways that you can become unconscious. You can also be knocked to zero HP and become "unconscious" without being asleep. Suggest you fold that into your answer. And when you say "fluff not mechanics" there isn't "fluff" in D&D 5e. see this link. Suggest that you remove that line, it adds nothing to your well organized answer. \$\endgroup\$ Nov 12, 2018 at 15:50
