Does True Seeing reveal an Elder Oblex’s simulacrum’s true form as an ooze?

I’m currently playing in a campaign where we’ve encountered an Elder Oblex. Before we ventured into its lair I twinned True Seeing onto myself and another party member.

Later on it was revealed that a pretty suspicious humanoid male we met down there was actually a simulacrum created by the Elder Oblex’s Sulfurous Impersonation ability.

The description of the ability is:

As a bonus action, the oblex can extrude a piece of itself that assumes the appearance of one Medium or smaller creature whose memories it has stolen. This simulacrum appears, feels, and sounds exactly like the creature it impersonates, though it smells faintly of sulfur. The oblex can impersonate 2d6 + 1 different creatures, each one tethered to its body by a strand of slime that can extend up to 120 feet away. For all practical purposes, the simulacrum is the oblex, meaning the oblex occupies its space and the simulacrum’s space simultaneously. The slimy tether is immune to damage, but it is severed if there is no opening at least 1 inch wide between the oblex’s main body and the simulacrum. The simulacrum disappears if the tether is severed.

From the description of Truesight in the Basic Rules/Player’s Handbook (emphasis mine).

A monster with truesight can, out to a specific range, see in normal and magical darkness, see invisible creatures and objects, automatically detect visual illusions and succeed on saving throws against them, and perceive the original form of a shapechanger or a creature that is transformed by magic.

So, while not necessarily the traditional definition of a shapechanger (typically associated with polymorph’d creatures or lycanthropes), clearly the Elder Oblex is shapechanging beyond its natural composition, and should be detectable via True Seeing, and the characters who had True Seeing active should have seen an ooze in the guise of a man.

Is this a reasonable deduction or a stretch? Perhaps there is there a more specific definition of what is or isn’t a shapechanger somewhere that I am missing?

How to reveal a time limit without videogaming it?

I am under the impression (so correct me if I’m wrong) that having a close time limit on objectives could be fun if there is not an abuse of the game mechanic.

So one hand, I want my players to find out about this time limit in the right moment:

Oh no, the truck where we hid the MacGuffin just left west, that’s the direction of the bridge that was blown up! And in the foggiest day! Let’s us hurry up pals!

But on the other hand I don’t want to video-game the event1 or spoonfed them the info. The truck is going to leave at 9, and crash at 11 if nothing is done. Only the guard and some employees know this. If my players think getting a drink after a rough day is more important than taking care of the MacGuffin, that’s part of TRPG.

Still I’d like to give my players as many chances as possible to find out there is a time limit, or to connect the dots.

DM: So the guard tells you that truck just left to another town via West Street, the unique, long street that reachs out of the city.

Player: (Doesn’t remember the bridge is west) Mm okay, maybe we could find out tomorrow where it’s headed.

This is even trickier for events the party doesn’t know about, BBEG plans, rituals, man-made catastrophes ("Hey let’s open this cursed ancient tomb in the name of archeology"). In this case it’d feel even more unfair, as the players didn’t get to make any decision, they were just slow or oblivious, and we completely miss on the adrenaline rush .

How can I improve the odds of players finding out about time-sensitive events at the right moment? Better even if they are slow or dense that day.

Why don’t changelings reveal themselves?

I am preparing to run my first Changeling: The Lost game and just read over the rule book. One thing I don’t understand is why the mortals don’t know about the Changelings.

Vampires have strong reasons to hide from the mortals. The mages in Mage: The Awakening would actually have a hard time revealing themselves even if they wanted to. But Changelings can reveal themselves to mortals (p. 108). There are some negative consequences to doing so, but those consequences are primarily supernatural in making it easier to track the Changeling. I haven’t found anything about the mortals forgetting or rationalizing a changeling that has scoured her mask or overt use of contracts. In, fact there are some advantages to forming a contract with mortals and the types of contract discussed might involve the human knowing the changeling is at least somewhat supernatural.

I see plenty of reasons an individual changeling may not want to out themselves specifically, from the risks of attracting the Huntsmen to changing relationships she doesn’t want to change. But I don’t see anything preventing the world from knowing about the existence of changelings in general.

So, why don’t the mortals know, at least in general terms, about the existence of changelings and the True Fae?

Will Googlebot click a button/link to reveal AJAX content?

my client has to inform it’s customers about some new regulations that the Googlebot should NOT crawl. It is not possible to place this information on a separate page and disallow Google to crawl it. So the idea is to place a button/link on the page, that will AJAX-load the corresponding information only when the user clicks it. My assumption is, that Google is unable to click the link and crawl that specific AJAX content.

Am I right? And if yes, is there an official documentation that proofs my point on this?

Can’t one reverse engineering Chrome source code to reveal Widevine and friends keys?

If I understand correctly, Widevine, FairPlay and PlayReady are all security through obscurity. Given the popularity of services using them, can’t someone just RE them and find exactly how their work? If so, was it done? If not, why? If this (can be) done, why people continue using these services?

How do I reveal the Big Bad only by foreshadowing, without the reveal being too early or late?

What I plan for my campaign is to drop hints about some greater evil, and whenever my players reach the natural point of realization, have them go off on a search to stop it. I wanna do it naturally, so I don’t have a point in mind where I have a big reveal, I want to players to create it, in a manner of speaking.

How do I foreshadow the Big Bad (without leaving too large a trail of clues so that they realize it too soon after the campaign starts) so there’s not that same anticipation, but not so vague that they get frustrated?

Does casting the Detect Evil and Good spell on a killed monster reveal anything?

If I kill some kind of evil creature like a zombie, chuck it into a shallow grave and burn its remains, would casting detect evil and good on the skeletal remains reveal anything?

Or do destroyed/slain monsters immediately stop registering for such effects?

The spell does not specify if the creature needs to be alive, dead, or whole. However, it may cease to be considered a creature if it is dead; I do not know.

The detect evil and good spell description reads:

For the duration, you know if there is an aberration, celestial, elemental, fey, fiend, or undead within 30 feet of you, as well as where the creature is located. Similarly, you know if there is a place or object within 30 feet of you that has been magically consecrated or desecrated.

Additionally, would you know that it was undead? Or just that it is one of those types of monster?

Also, does it remain ‘undead’? Once undead, always undead?

I assume this spell only reveals if the monster is one of the types in the list (not which one?), and not alignment like I think perhaps past editions of D&D have done.

How much information should the GM reveal with a Legend Lore spell?

The PCs decided they want a minor artifact (deck of many things) and decided to cast a Legend Lore to get information about it. They intend to barter, but if it stands within the grasp of an evil NPC, to take it by force.

How much information should I give them? How tough should I make their quest?

Obs.: I have no restraints about them getting the deck or suffering the consequences. Actually it is a very fun item and I would have no problem in adequating the campaign. I can already predict lots of laughs from misfortunes or satisfaction from fortunes.

Obs. 2: the group is quite accomplished and the best PCs (who haven’t died yet) are level 16 right now.
