haven't already trained? hmm.... skateboarding. tastes slightly spicy, don't know about any more taste details.... side effects? ooohhhh if it wasn't for me i'd add [fragile bones] but i don't hate myself so no side effects; that's not too greedy is it

Amazing skills is most art fields, it's pepsi flavored, and the siee affect is that i'm cute ash

Music production (composition, arrangement, mixing, playing) and I become famous only yo withdraw and stsrt releasing under a pseudonym, and it becomes a cycle every few years when I just want peace.

Its fizzy with hints of fruit.

the potion gives me mastery in writing risc-v assembly (since it can't be x86 assembly as i already trained that), it tastes like beer (i like beer)
as a side effect it makes me time travel to 1985 for 30 minutes where i convince stroustrup that adding oop to c++ is a bad idea

Strawberry flavor potion that allows me to summon nearby wildlife for teaparties 🙏

level design. it would probably taste like an energy drink and give me a compulsion to enter every
level design contest for a game i like

hmmm, i took german for 3 years in high school, so idk if that counts as something i've trained. but i'd love to be a polyglot with ideally all the languages, it's one of those "realistic" superpowers (obv not all languages) that i've always wanted to have. if not all languages, then ig dutch and/or italian would be priorities for me

i have a feeling it'd have a rather intense flavour, probably a combination of the most popular food(s) from the regions where each language is primarily used

side effects: lower proficiency in starting language(s), easy to mix up languages in conversation

Hmmm, dancing maybe. Taste? Idk, I'd prefer something like strawberry, but not very sugary. Side effects may include more graceful walking per default

i'd like to have a potion, that gives me mastery over myself 🥴

Hmm, it'd be either strawberry or blackcurrant - instant mastery in archery. Side effect: turns me into my FFXIV character, though that'd be preferable~

Flavor: Alcohol. Skill: Drunkness Level 2. Side effect: Drunk.

the potion lets me speak every language including animal languages, so that i can speak to and understand anyone or anything capable of communication. It tastes like guava juice, and the side effect is it dyes my lips and tongue bright pink.

tastes like water. gives me mastery in creative writing. side effect is that i no longer have any free time, because i'd be writing yuri all day

It tastes like mangoes and it let's me be the best artist EVAR, but, I lose one of my shoes every month like Sam Winchester..

Does it have to be some ability that you can already get in reality, or can it be some sort of crazy thing like flying (without the use of an airplane?
