This addresses adventure creation. I'm talking about published adventures.
I quoted the relevant portion of your post I was addressing. And that portion was not talking about published adventures, but the rules themselves. You were pretty clear that you had two points, and they were that 1) the published adventures don't support X, and 2) the rules don't support X. So I quoted you the second point about the rules you appear to have missed. And now you're saying you didn't mention that second point about rules, despite my quoting you directly? And you're doing it in response to someone quoting my response to you, rather than directly to me?'
You're missing the entire point of this thread by a mile
Oh no, you just punted one of the two points you were making when someone actually addressed that point. I can start to address your other point next, but first I wanted to establish your rules point was incorrect.
So now that we have addressed that the rules do in fact directly deal with this issue in the DMG, which adventure are you referring to that does not support this issue?
Tell you what, I happen to have Princes of the Apocalypse handy, so let's start there.
Once the PCs are done in town the first adventure starts on page 29, which references the DMG chapter 5 (that's the section I was quoting above), and then page 30. Not coincidentally, page 30 starts with "Random Encounters" and calls for four random encounter checks each day (and some of them are quite difficult). And how do you know when a Random Encounter is supposed to happen relative to where the adventurers are at? DMG Chapter 5, starting with page 85, Random Encounters, "Create Urgency" and "Drain Character Resources" followed by "Triggering Random Encounters" which specifies, for example, that the characters have stopped for a short or long rest.
The adventure is peppered with references to checking for random encounters throughout, adjusting the check frequency accordingly. For example, page 54, "Random Encounters. Characters lingering in the castle yard are likely to encounter various denizens of Rivergard going about their business. Check for random encounters once per 5 minutes during the day or once per 15 minutes at night." Similarly on page 68 in the Mines "Check for random encounters once per hour. "
Later the adventure sets up a series of special counterattacks. Starting on page 76, "If the characters try to camp in any of the four temples while its elemental prophet is still alive, the prophet gathers reinforcements and sends them to attack the intruding party...Likewise, it isn’t safe to camp in a cleared Haunted Keep. The elemental prophets divine the characters’ location and send forces to harass the party. Small bands of cult raiders and mercenaries roam the Sumber Hills, so it’s a simple matter to order one such group to attack the characters at one of the Haunted Keeps. (See the “Random Encounters” section in chapter 2.)" It further describes additional retaliation, "As the party continues the assault on cult strongholds in Tyar-Besil, the elemental prophets look for ways to hit back hard, using their devastation orbs. The timing of these retaliatory encounters coincides with the party’s progress in overcoming the four temple complexes." Then further on that same page under "Reckless Hate" there is another rest-interrupting attack, "While the characters rest, trouble arrives on their doorstep." The next page, under "Warning" describes another interrupted sleep.
It gets worse from there. Page 82 has random encounter checks every 10 minutes. Page 85 has a random encounter every time the characters travel the main connecting path; not a random encounter check, but a guaranteed random encounter every single time. Page 86 has further hourly checks, page 93 has a random encounter on a roll of 1-6 on a d20 every time the characters pass through that area, page 101 has the same but on a 1-8, page 124 has a disrupting environmental effect on a roll of 11-20, page 128 has random encounter checks every 10 minutes, Page 135 every 30 minutes, Page 138 specifies a room specifically for a random encounter, Page 142 has random encounter checks every 30 minutes, etc..
And none of this even tries to count the number of intentional multi-part encounters.
So yes, when you use the DMG rules (which the adventure references) on how to use the random encounters the adventure references and the time frames and types and frequency of checks the adventure references, you should not be finding much issue with this problem using this published adventure. The rules address the issue, and the publish adventure uses those rules to address the issue.
The better question at that point is why is your DM not using those tools the rules and the adventure supplies to address this issue? Are you guys just never encountering multi-part encounters and random encounters while resting like the rules and the published adventure provide for?
