Are Gloom Stalker Rangers better than the normal ranger subtypes that appear in the players handbook?

I am joining a campaign with some friends and they suggested that I should play a Gloom Stalker Ranger. I rarely get a chance to use things from anything other than the players handbook so I want to try something new. I want to know if it’s even worth playing a gloom stalker and still contribute to the party with both damage and role-playing capabilities because currently my friends are playing rogues and I want to fit the setting (which is a thieves guild type setting) and still do a good amount of damage to help balance out the party.

Can Major Image and forced perspective make illusions appear larger?

In the game I’m running, the PCs are about to embark on a wilderness trek during which they will be harried by an opponent who has access to the major image spell. This opponent seeks to distract, mislead, and delay them, forcing them to spend more time and resources reaching their objective than they would otherwise.

I am trying to determine what is possible within the constraints of the major image spell description. One thing that occurred to me is that, while the spell’s effects are confined to a 20′ cube, they might seem to be spread over a much greater area by tricks of forced perspective. For example, an illusory, 20′ tall castle suspended in mid-air between the party and a distant hill might appear to be a full-size castle settled on the hill. Or a 20′ wide illusion of a wall of flames might seem to be consuming a vast span of the horizon.

Or alternatively, an illusory pit might seem to be much deeper than 20′ by "drawing" its walls and bottom in such a way as to make it seem deeper.

Can forced perspective be used with major image in this way?

Are there potential drawbacks to allowing this? Would any modifiers be appropriate for investigation checks to "disbelieve" them?

When did the idea of a fluff (or flavor) vs crunch distinction appear?

I find myself involved in discussions frequently where one person will claim that a piece of text in a rulebook is "just fluff" or "pure flavor" and can be "refluffed" by the players with little or no DM oversight, while others are "mechanics" or "crunch" that requires a house-rule to change.

Specifically, the things cited as "fluff" are those that do not have an attached dice roll or explicit benefit/penalty listed. Things like the descriptions of classes, feats, things like "Druids won’t wear metal armor." On the other hand, "mechanics" or "crunch" includes rule text that has direct, explicit application to the game world, especially when expressed in pseudo-mathematical form (such as dice rolls, damage, or bonuses and penalties).

I know that 4e had a specific rule that said that descriptive text in italics in an ability entry or elsewhere was just an example (ie fluff) and could be changed at will. But I’m pretty sure that this distinction pre-dates 4e–I remember hearing it invoked to justify taking prestige classes (3.5e) completely out of context and apply them without satisfying the "fluff" prerequisites (such as meeting/being trained by someone of the appropriate faction).

I’m interested to know where (and in what context) this distinction first (or dominantly) arose. More than that, I’m interested in finding examples of where this distinction has direct rules support. So far, 4e D&D is the one I know of. Citations to rulebooks would be wonderful. This is not D&D specific, although most of my knowledge is of D&D’s history.

How to manipulate solution outputs that appear in a list?

I have a list {E, {p, ϕ}}, and I need values E, p, and ϕ such that I can later on do operations with them (like ArcCos[p], etc.). I will be repeatedly generating the values in the list, as a list, so doing this by-hand is not an option. How do I get them out of the list?

In this case, the values E, p, and ϕ exist such that they appear as p -> 0.097, ϕ -> 0.03, etc. I need them such that calling, for example, for list = {E, {p, ϕ}}, list[[2,1]] yields 0.097 and not p -> 0.097. This is the issue.

Do Venture-Captain Sayrin Fyrewine or the Gristmill lodge appear in any published Pathfinder adventures?

I’m looking for information about VC Sayrin Fyrewine and her Pathfinder Lodge in Gristmill. I can find cursory mentions of them on the Pathfinder Wiki here and here. Those descriptions seem to be taken from Seekers of Secrets and Guide to the River Kingdoms, but I was hoping for a little more detail. Do they appear in any PFS scenarios or other published adventures?

Fonts appear darker even using the same rgba values

I’m trying to build a layout like google drive, and have managed to get as close as possible. One thing I’ve noticed is, even when I’m using the same font roboto 13px and the same rgba values rgba(0,0,0,0.72): the font on my site appears a bit darker than the one on google’s site. How can this be happening? When looking at the two in Chrome Dev Tools there’s a difference in contrast. How do I set this contrast value? Google’s is 9.29 and mine is 1.42. Can this be causing the difference?
