How to get magic blade skill with main quest?

Hello every body.
I have a problem. I hope someone can help me.
Does anyone how to get book of magic warrior from main quest? I see this text in official website but dont understand what they mean.

Help me please. Thank you very much.

 

Open the treasure chests in the maps Maia diela to Lunagent mountain, the maps you visit during the mentioned chapter of the main quest to have a chance at getting the book. It is not guaranteed.

 

Thanks for help. I ll try.

 

Good luck! I haven't managed to get any yet sadly

 

Hope someone can put a list of the said maps. Most players love to tap that skip button in the corner screen a lot to notice to what chapter he is in.

 

You can't skip it the first time you run through it, so you should see em all

 

I lucked out and got Book of Darkness in garden of sublimation. Sold it cuz I'm not interested in new skills lol. Haven't really heard anything good about either tree.

 

Given the choice, I think Dark suits my play style more. Free heals for days. ^_^

 

Well I can (I guess)
