Low on funds, and more than a little annoyed with him, Geralt decides that Jaskier can be more useful than just singing a couple of songs.
Note: I've really only watched The Witcher S1 when it first came out, and haven't revisited it since. I know entirely nothing about the game. But this is apparently a thing, judging by how many fics I've liked on AO3 with the tag "Improper Use of Axii" LOL
