Yensa’s Genus is "Ichthian", and the descriptions of the Monographs usually refer to the Genus, like "Beast" or "Avion", right? But, apparently Yensa DOES have a Monograph drop, the Yensa Fin, so there’s gotta be one that affects it. Though, no one mentions Ichthians.
Thing is, every "Grimoire FAQ" on Gamefaqs just has the descriptions taken from the game, so it wouldn’t say about Ichthians. Also there isn’t exactly a Bestiary there, and the ones there are don’t have that information.
I’m saving gil here, so I don’t want to get the wrong Monograph, each time buying the only one(s) I’m gonna need for the next area I go to.
So, I’ve tried googling many different things with the keywords "Monograph, Bestiary, Yensa, Fin, Ichthian" and even then it took forever and eventually after several tries it took me to a place that said it’s the Mage’s Monograph. I bought the Mage’s Monograph, yet I’m not getting any Yensa Fins. Is it just my luck, or do I have the wrong one? I’m starting to think it’s the wrong one because it’s supposed to be 20% drop rate.
Yensa, not Urutan-Yensa. Yensa are those big fish things.
EDIT: So it was my luck after all, got a couple fins. 20% chance… I’ll have trouble believing that but alright.
Well, if you noticed, I said I already got them. So this thread can die.
But since you asked, if by "Gil" you mean "Bazaar Goods", then yet.
And I don’t believe Stealing has an effect on Monograph drops… eh?
Though I love how in this game you can steal and drop from the same enemy where in most others you can’t.
The thread can die I just like puzzling questions and having an answer to one, I just couldn’t resist posting.
I think if you steal from and kill those pumpkin looking things… umm Alraune you get Succulent Fruit which is worth 363 Gil each. Pretty good for saving up Gil. I think I’ve been in you’re exact situation before. I asked a similar question on the Playstation forums and they told me this little trick.
