Do you lose your prestige class features when you no longer meet its requirements?

Certain prestige classes detail a list of requirements that are possible for the player to lose (alignment, casting at a certain level), but not what happens if you no longer meet those requirements (acting in an opposed way to your alignment, suffereing from energy drain). Some classes and prestige classes do detail what happens if you no longer meet your requirements, but not all do so.

So I am asking: if you no longer meet the requirements of your prestige class by choice or external influences, will you lose the class features gained from it, despite this loss not being detailed in the class itself?

Does a Character with a Custom Lineage belong to a race, for the purposes of racial requirements?

Tasha’s Cauldron of Everything introduces new character options. In the Customizing Your Origin subsection, there is a side panel that details the Custom Lineage options.

This option allows you to, "instead of choosing one of the game’s races for your character at 1st level", select among a few options to shape your character’s origin.

It is unclear if the resulting character is actually part of an official race, for the purpose of picking racial feats, attuning to race specific magic items, or picking race specific subclasses.

How does Arcane Armor’s removal of Strength requirements apply at a table using the Encumbrance variant?

The Armorer Artificer’s Arcane Armor feature says:

If the armor normally has a Strength requirement, the arcane armor lacks this requirement for you.

This is in reference to the following regarding certain heavy armors:

If the Armor table shows "Str 13" or "Str 15" in the Strength column for an armor type, the armor reduces the wearer’s speed by 10 feet unless the wearer has a Strength score equal to or higher than the listed score. [PHB, pg 144]

However, the Encumbrance variant says, in part:

When you use this variant, ignore the Strength column of the Armor table in chapter 5.

If you carry weight in excess of 5 times your Strength score, you are encumbered, which means your speed drops by 10 feet. [PHB, pg 176]

Is there guidance for how to apply the Arcane Armor feature at a table that uses the Encumbrance variant?

What are the range and requirements of a Dismiss action?

Using his sharp ear to guide himself, the little cat walked gently across the unstable roof of the inn to the window where the conversation was closer. Even with the window closed, it was clearly the refined voice of the Marquis’s right hand. He was commanding two rough men, probably two quarrelsome mercenaries, to engage the noble soldier in a street fight, so they could later accuse him of starting such fight and … Oh no! another cat is in the roof, and is approaching hostile!

Clare opened her eyes. She was in the ground floor of the inn, pretending to be a simple customer – I have to dismiss my poor familiar before the cats start a fight and alert the men that someone could be listening to them – but she can’t even see her familiar from there.

Some effects, spells and even some magic objects can be dismissed using an Action, a Bonus Action or other. But which range and requirements does the Dismiss action have?

  • Lots of them (Dragon Wings, Disguise Self and others) have a range of ‘Self’, so the range of the Dismiss action doesn’t seem to be a problem. But can you dismiss them being Prone, Restrained, Grappled or when you are trying to be discrete? Does the Dismiss Action have Verbal, Somatic or Material Components?

  • Others, like Find Familiar or Mage Armor, create an effect that can be very far before ending. Do you have to see the effect to dismiss them? Is there any limit on the range?

  • If the effect was created by a magic item by itself (not merely giving you the ability to cast a spell), like Instant Fortress, do you have to be in possession of, touching, or near the magic item to dismiss it?

  • Extra: Is putting a familiar into a dimensional pocket is comparable with the Dismiss action?

Are there any examples of “level requirements” that can be ignored with Use Magic Device?

The Thief Rogue’s 13th level feature allows them to ignore requirements on the use of magic items:

Use Magic Device. By 13th level, you have learned enough about the workings of magic that you can improvise the use of items even when they are not intended for you. You ignore all class, race, and level requirements on the use of magic items.

I’ve found examples of items that have class requirements (e.g. a Rod of the Pact Keeper) and of items that have race requirements (e.g. a Moonblade). However, I couldn’t find any examples of items that have level-based requirements on their use.

Are there any, or is this a redundant (/future-proofing) clause in the feature?

Items from any published 5th edition material would be welcome as answers; if the only examples are in UA that would be useful information as well.

How does an inverted index reduce storage requirements?

In p. 7 of the book "Introduction to Information Retrieval" (by Manning et al), the authors explain how, given a collection of text documents, an inverted index is built by tokenizing, then sorting the (term, docID) pairs, merging multiple occurrences of the same pairs, and the pairs for each term are grouped into a posting list. It is then mentioned that "Because a term generally occurs in a number of documents, this data organization already reduces the storage requirements of the index." My question is: how are the storage requirements reduced? It seems to me that if a term occurs in $ k$ documents, then these $ k$ documents’ ID’s must all be mentioned in the linked list for this term.

If a term occurs multiple times in the same document, then because the inverted index mentions a docID at most once in a term’s list, there is a reduction in storage. But this condition is different from the condition that a term occurs in multiple (distinct) documents.

What is the industry-standard recommendation for where non-functional security requirements end and enterprise requirements begin?

I have been tasked with coming up with security requirements for a project. I am finding it difficult to find the line between where project specific, nonfunctional requirements end and general security requirements for the enterprise begin.

For example, access to an SFTP server must require IP whitelisting vs. privileged access reviews must be conducted on a semi-annual basis. The former is specific to the project at hand while the latter should be applicable to the organization as a whole, the current project included.

Does the optional Overrun rule override the creature size requirements?

The standard moving through creatures spaces rules state that in order to do this, a creature must be two sizes larger than the one they want to pass through.

The optional overrun rules in the DMG (chapter 9) now require a roll, but does it remove the size differential as well and completely replace the rules around moving through other creatures?

Prime sphere requirements to use Tass in Mage 20th Anniversary Edition

I’m confused about what level of Prime is required to use Tass in the Mage 20th Anniversary Edition rules.

In the main rulebook the following statements are made:

M20 Rulebook:

  • p 332: “To absorb Quintessence energy from the materialized Quintessence of Tass requires Prime 3.”

  • p 520: Prime 1 sphere description says: “A beginning study of Prime allows the mage to perceive and channel Quintessence from Nodes, Tass, …”

  • p 520: Prime 3 sphere description says: “… the Prime-skilled mage can draw both free and raw Quintessence from Nodes, Junctures (special times) and Tass …”

How do you DO That Rulebook says:

  • pp. 43-45: “Any mage with an Avatar Background cab absorb that Background’s worth of Quintessence from a Node or Tass …”

First off – are there ways to use Tass other than absorbing the Quintessence into your pattern? Can you spend Tass to gain Quintessence effects like lowering the difficulty of a roll without absorbing it into your pattern?

And with regard to what levels of Prime are required to do these things, I can see support for any of these positions:

  1. You don’t need any Prime at all to absorb Quintessence from Tass into your pattern, as “Any mage with an Avatar Background” can do it (How do you DO That pp. 43-45)
  2. You need Prime 1, as the description for that sphere says Prime 1 allows you to channel Quintessence from Tass. (M20 p. 520)
  3. You need Prime 3, as that is stated on M20 p. 332 and p. 520 explicitly

I have reviewed other answers at: How does the Prime Sphere affect gaining and storing Quintessence in M20? but it left me more confused than enlightented.

From a gameplay perspective, requiring Prime 3 to use Tass seems to defeat much of the purpose of Tass – as it can’t be readily exchanged between mages as portable Quintessence unless they have Prime 3.
