I realized I was a bit harsh in my comment and I apologize. I was in need quickly so I could source a honeybone. You put a lot of work into this so thank you.

Perhaps, but at the same time, trying to keep it balanced so that its not just some cheat tool is important here.

Needing 2 source points stinks, imo. Cheers.

im at the lady ship but i can't find the book can you please make some pic of the places where we can find it?

I'm sorry, I put this book in my bag, found it.

Skillbook from your mod - not to be wasted when using? I gave that skill to everyone a long time ago. Then (on the Reaper`s Coast) I hired a mercenary. And I want to teach her this skill, but I don't see (or forget) the skill book, where can I find it?

(as in its interesting because it sounds balanced or the fact it is)

interesting, to see it balanced.

Basically the skill when used will cause the area affected to rain source. Useful if you have a summon that is infused and has source skills available to them, or just transfer some source to a buddy. It costs 2 Source Points, and 2 AP, so you're not going to just be giving it out for free, though if you plan it right you can double your investment.

As for location, generally they're near where you start in each chapter. Theres some on the hold where you wake up, some where you start in Fort Joy, Some on the Lady Vengeance in the High Seas, as well as when shes at Reaper's Coast (in case you're past the High Seas part), and some at Arx.

So I think the skill title is a little self-explanatory... but a brief description might help regardless?
Also a location of where to get it.

Please leave any comments or concerns so I can handle them.
