That's actually a matter of some contraversiality.
You can't actually just replace "my" in a sentence with an adjective and have it come out sounding natural. You can say "this is my house" but you can't say "this is big house". You're missing a determiner, not an adjective.
Possessive determiners are determiners which express possession. Some traditional grammars of English refer to them as possessive adjectives, though they do not have the same syntactic distribution as bona fide adjectives.[1]
...
The words my, your, etc. are sometimes classified, along with mine, yours etc., as possessive pronouns[3][4] or genitive pronouns, since they are the possessive (or genitive) forms of the ordinary personal pronouns I, you etc. However, unlike most other pronouns, they do not behave grammatically as stand-alone nouns but instead qualify another noun, as in my book (contrasted with that's mine, for example, in which mine substitutes for a complete noun phrase such as my book). For that reason, other authors restrict the term "possessive pronoun" to the group of words mine, yours etc., which replaces directly a noun or noun phrase.[5][6]

This is further complicated by the fact that some words are sometimes true pronouns, and sometimes possessive determiners (his, her, its). In this way, it is difficult to fully separate the role of possessive determiner from the role of pronoun.
But thank you for making me research it a bit more.
I remember the time almost an entire play session was spent arguing about how to get to an island in the bay. We were in a city, and to be fair the PCs were fugitives hiding from the regent of that city, but getting to the island itself was always meant to be just as easy as hiring a boat.
I mainly GM Adventure Paths, so it's a bit different, but typically aim to prepare up to a whole book in advance. Which really is overkill, but it does mean that I'm never in a rush or panic over it, and lets me devote extra prep time to whatever I feel deserves it.
Play a Pathfinder 1e Unchained Monk, pick up Breaking-Down Koan, flavour your koans as devastating puns, and you can spend ki points on puns.
You can also pick up the other koan powers, but I think Breaking-Down Koan fits best.
Text reproduced for the curious:
Breaking-Down Koan (Su): A monk with this ability can spend 1 ki point as a swift action to present a paradox, riddle, or complicated question to a creature within 30 feet. The creature must succeed at a Will save (DC = 10 + 1/2 the monk’s level + his Wisdom modifier) or be confused for 1 round. This is a mind-affecting, language-dependent effect. A monk must be at least 8th level before selecting this ki power.
Yeah, Pathfinder clerics are kind of insane healbots even without compromising their other abilities, but then Pathfinder is—in my admittedly limited experience of 5e—generally a lot more generous with class features than 5e is; and that's true whether you're talking 1e or 2e Pathfinder.
GIF, or Graphics Interchange Format, is just another image format, even if it can support animation. In particular, it's an image format that works well for images with simple palettes, and was presumably chosen by this artist because it fit their art style...
...Is the comment I typed out before checking and seeing:
Jpeg artifacting, and
It's actually a webm, not a gif.
The image actually hosted on the artist's website, however, is actually a gif, with a 64-colour palette.
It is entirely reasonable to limit the spectrum of playable characters to those who have some motivation to play the game with the other players. Stealing loot will reasonably upset the other players (not just the characters), by reducing the ways in which they can play the game. So no, it's not just creative freedom, it's being a dick. It's choosing to be a dick. GMs telling you not to do that aren't just limiting your creative freedom, they're telling you to stop being a dick or they'll stop playing with you.
There's a funny thing about Darkvision, since depending on the exact game and edition you're playing, it doesn't always even work in dimly lit rooms, only complete darkness. Which gets a bit silly, sometimes.
You can write all the steamy stories and draw all the fanart you want, just don't go around trying to say "they have a point!"
