D&D 5E What interupts a long rest?

clearstream

(He, Him)
The resting rules in the PHB don't say to extend the rest in so many words, but it's at least as reasonable to read the requirements (at least 8 hours total, at least 6 hours sleeping, any activity "light") to mean that time lost to other activity must be added, as it is to interpret the wording that any fighting at all will interrupt a long rest to the point it must be restarted.
I agree that you could reasonably play that way, joining others in not following the RAW.

I think it's a reasonable reading of the words on the page. Personally, I don't keep that sort of track as DM (unless, of course, I need to) but as a player it wouldn't bring me up short the way ruling that any fighting at all meant the long rest needed to be restarted would.

No. Nowhere do the rules state that.

An interruption that lasts an hour or more means that you must restart. An interruption that lasts less than an hour is still an interruption, but allows you to pick up resting afterwards, from the point where you left off.
To count as interrupting, the adventuring activity must be an hour or more. That defines what an "interruption" is for the purposes of the game mechanic. Adventuring activity of less than an hour is not an interruption. Look again at the sentence and ask yourself, how is an interruption defined by this sentence?
If the rest is interrupted by a period of strenuous activity—at least 1 hour of walking, fighting, casting spells, or similar adventuring activity—the characters must begin the rest again to gain any benefit from it.
It is defined as "at least 1 hour of walking, fighting, casting spells, or similar adventuring activity". It is not an "interruption" per RAW, unless is is exactly that. Less than an hour of those things is not a period that interrupts. This is really a straightforward parsing of the text.

It's a way to add some words to the page, to reach the reading one prefers, I grant you!

The sentence doesn't define what is or isn't an interruption. It only defines what is enough of an interruption to require you to start over from scratch.

The rules say that a long rest consists of a period of eight hours during which you do nothing other than sleeping or light activity. It would therefore be reasonable to conclude that any time spent doing other things (let's just say taking a half-hour walk, to avoid the original controversy of the topic) does not count towards those eight hours.

Whether you define that half-hour stroll as an interruption, or a diversion, or any other word you want to use for it, it wasn't a period during which you were either sleeping or performing light activities such as reading, talking, eating, or standing watch. Therefore it doesn't count towards your long rest, and you'll need to spend another half-hour doing something that actually does count towards your long rest.

You were making an argument for extending: at no point does the RAW say that anything that fails to interrupt a rest (meaning it starts over from scratch) extends the rest.

That is your addition, which you are free to make. It is not what the words on the page say.

The words on the page say that a long rest consists of 6 hours of sleep and 2 hours of light activity, such as reading, talking, eating, or standing watch. You are the one saying that some of that period can be taken up with doing things other than those activities. That is not what the words on the page say.

I think I see where you run into problems. The RAW does not say how much you must sleep or perform light activity. Rather it requires sleep (without saying what amount) and light activity (no more than 2 hours) over an 8 hour span. It also allows for less than an hour of fighting etc to be non-interrupting.

Therefore, over 8 hours, you cannot spend more than 2 hours in light activity. You must get some sleep. And you may fight etc for up to anything less than a full hour. If one wants to be exacting, the sleep could in fact be just over 5 hours. Using the rest of the time for light activity (no more than 2 hours) and adventuring (less than 1 hour).

My memory matches this claim, but the actual words of the text do not. I think this might be one of those areas that got errata at some point after I learned the rules. But I don’t care enough to check.

PHB said:
A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps for at least 6 hours and performs no more than 2 hours of light activity, such as reading, talking, eating, or standing watch.

It takes at least 8 hours, and the character must sleep for at least 6 hours of that period.

I suppose an argument could be made for the up-to-an-hour of strenuous activity taking the place of some of that light activity, but to me it's not the most natural reading of the paragraph.

And that all said, I suppose you have thought through the implications of your version?
  1. Start a long rest: sleep for 6 hours and perform a minute shy of 2 hours of light activity.
  2. Adventure for 59 minutes
  3. Perform a minute of light activity
  4. Refresh abilities
  5. Continue adventuring
Extending is gruesome, mechanically.

Here, for your convenience. And you are right, the errata differs! [EDITED to give the errata'd version.]

Long Rest (p. 186). The first sentence now reads, “A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps for at least 6 hours and performs no more than 2 hours of light activity, such as reading, talking, eating, or standing watch.”
Again, no more than 2 hours. No more than includes less than, i.e. one hour of light activity. It comes to the same thing (and was what I suggested in my first post in this line.)

Sure, if you want to game it like that. But I think that goes against the spirit of the rules at the very least, since they talk about interruptions rather than deliberate excursions.
Here, for your convenience.


Notice that the amount of sleep required isn't defined, amounting to "any", but timings are put on everything else.
Are you maybe working from an old version of the text? I'm pulling from the current version on D&D Beyond, which includes a stipulation of 6 hours of sleep.

Reread. The words "no more than" mean it must be less than, not that it must be 2 hours!

I pointed out earlier that it doesn't matter. It comes to N hours of sleep where N can be 5 hours +1 minute (pre-errata) and is 6 hours (post-errata) plus up to 2 hours of light activity (but possibly less, such as when 59 minutes are taken up with adventuring.)

It’s probably best that that got errata. Rereading it, the wording strikes me as ambiguous enough to be interpreted as not actually requiring sleep. And if you do sleep, you can’t do it for more than 2 hours. Almost certainly not the intent, but that “or” was a poor choice.

Perhaps that is what they wanted to clarify. That a long rest requires N hours of sleep. That was where I started this line of discussion from.
