That potion was not made with elves in mind :D. It's non-addictive on Humans like cicero but gwyneira ...well, she MIGHT not get addicted (leave it up to you) but she's definitely going to start hallucinating an hour from now (good time to hint us a bit about your char).
It's really potent stuff. Think LSD + digestible adrenaline + an energy drink for elves. The LSD part is the portion Humans are resistant to (think how alchohol is less toxic to man but kills almost everything else in nature, elves have more picky diets for a very good reason). She's going to crash HARD once 8 hours are up.
Btw cicero KNOWS it's meant for Humans, that dude told him like when he first bought it! He even rolled a crit to know this stuff! He did not state the side effects, sure, but blame the customer, not the salesman!
I'mma give you an advantage bonus to atheletics related (jumping, dodging, bodily movements kind of things) skills while it lasts, also can cast two medium spells more (three initially but one used to freeze the stream).
