In “Elves of Evermeet”, how does the “construction” spell work?

This is in the 2nd edition book: Elves of Evermeet. On page 65 there is the description for a spell: Construction. Part of the description says:

The caster can create any object with a volume equal to 1,000 cubic feet (10x10x10 feet) per level. Each 1,000 cubic feet so created takes one entire day. Once created, the object can be added to at the same rate (1,000 cubic feet per day) for as long as the caster wishes.

This made me wonder, assuming a level 20 caster, how much volume can be created/added to in a day? Is it 1000 cubic feet/level, or only 1000, in which case, what is the point of mentioning the caster level?

Are Half-Elves supposed to have a slender build like Elves, or are they supposed to have a build that’s intermediate between Humans and Elves? [5e]

The Player’s Handbook’s weight descriptions for Half-Elves are inconsistent. The Half-Elf section in Chapter 2 (pg. 38) says:

They range from under 5 feet to about 6 feet tall, and from 100 to 180 pounds, with men only slightly taller and heavier than women.

However, the “Height and Weight Range” table in Chapter 4 (pg. 121) gives a weight formula for Half-Elves of 110 + (2d8) x (2d4), which is 114 to 238 pounds.

This is very different.

Do we have any reason to label one description Correct and the other A Mistake? The 2018 PHB Errata are silent on this point.

Looking at the rest of the table’s formulas, Humans are 114 to 270 lbs, whereas Wood Elves are 102 to 180 lbs and High Elves are 92 to 170 lbs. (I’ve excluded the Drow because they’re significantly shorter.)

So are Half-Elves supposed to have a slender build like elves (100-180 lbs), or are they supposed to have a build that’s intermediate between Human and Elf (114-238 lbs)?

[As a side note, changing the Half-Elves’ weight modifier in the table from its current 2d4 (which is like a Human’s) to only 1d4 (like the Wood and High Elves’) would yield a calculated range of 112 to 176 pounds.]

Why are elves immune to a ghoul’s paralyzing touch?

I was reading Are Half-Elves immune to the paralyzing property of a Ghoul's Claw action? and it struck me that I have no idea as to why elves would be immune to the paralyzing touch of a ghoul, but it has nonetheless been part of D&D lore since Monsters & Treasure. Is this based off of Tolkien? Traditional lore? Gygax and Arneson’s shared world?

Are the female elves in this AL adventure actually Dusk Elves?

In the Curse of Strahd adventure, there are a unique subrace of elf called dusk elves, and the adventure has this to say about them:

So it seems that, during the time that the adventure takes place, there are no female dusk elves left alive

but then, in DDAL04-06 The Ghost, there are female elven characters such as Derali (p. 11) and the “very young female [elf]” (p. 13); however, their subrace is not specified. There are other examples of elves (without a specified subrace) in Barovia presented in other AL adventures, but this is the first one I’ve encountered with female elves included and even named (even included on the “Appendix: NPC Summary” page):

As an additional piece of information from the AL adventure, the Adventure Overview on p. 8 includes the following:

However, I don’t know what “Greenhall” is, or whether that invalidates some of my logic leading me to believe that these elves are dusk elves. The AL adventure itself (and therefore, meeting the elves) does take place in Barovia, however.

As far as I’m aware, there are no other elves in Barovia besides the dusk elves (certainly no other elves besides dusk elves appear in the Curse of Strahd adventure), which implies that these female elves (and for that matter, the other elves-without-a-subrace included in these AL adventures) are dusk elves, although it contradicts the quotes above from p. 232 and p. 237 that says they were all killed.

On other other hand, the quote from p. 232 also says “the dusk elf tribe” and p. 119 says “live in secret places such as this”, so this could be read to mean that there are other tribes of dusk elves in Barovia that had nothing to do with the events of Patrina (presumably not known about by the now-male-only dusk elf tribe), and therefore could still have females. However, this isn’t expanded on in Curse of Strahd, and is only hinted at in these AL adventures.

So I can only see the following possibilities to resolve the apparent contradiction in the above information:

  1. The female elves in the AL adventures are dusk elves, and they were just a separate tribe that had nothing to do with the Patrina incident;
  2. The female elves in the AL adventures were some other kind of elves (say, wood elves or something) and there are, indeed, no female dusk elves after all;
  3. Whoever wrote these AL adventures made a mistake…

Am I missing something? Which of the above is true (or is there an “option 4”)?

Can Elves move when they Trance?

Elves have the Trance trait :

Elves don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

Can a Trancing elf move, such as by slowly walking in circles (pacing), without interrupting the Trance ?

(Specific reason I’m asking : I have an Elven Speedster character whose concept includes to be “always on the move, lest he dies”, a bit like a shark.)

Can elves trance in armor without any downsides?

Xanathar’s Guide states

Sleeping in light armor has no adverse effect on the wearer, but sleeping in medium or heavy armor makes it difficult to recover fully during a long rest. When you finish a long rest during which you slept in medium or heavy armor, you regain only one quarter of your spent Hit Dice (minimum of one die). If you have any levels of exhaustion, the rest doesn’t reduce your exhaustion level.

Given an elf trance isn’t “sleeping”, does wearing armor negatively impact the effects of the trance?

Are Valenar elves and Aerenal elves different races of elves?

I have been a GM of D&D eberron for around 2 years, and there is something that I always ask myself:

Are Valenar elves and Aerenal elves different races of elves?

As I don’t know, I let my player choose between wood elves and high elves as subrace (as drows are in Xen’drik and so they are not involved in this question), but for me it would be logical that Valenar = wood elves and Aerenal = high elves.

Are Shadar-Kai and Shadow Elves the same?

Now that Shadar-Kai are officially elves in 5e D&D, is there an official source or even semi-official (WOTC tweets, Designer blogs / podcasts / videos, Unearthed Arcana, etc.) that links these pale neutral-ish elves with the pale, neutral-ish Shadow Elves from the known world aka Mystara.

I have so far not been able to find even semi-official confirmation, especially since Mystara is seldom officially mentioned in a 5e context. But it really seems like they have many points of overlap.

Personally, I intend to make them one and the same.
