There's a nifty folder in the game files, called "Manuals".
It offers an already known Sword Coast Survival Guide and two new guides,
And, man, these are awesome manuals, they can offer you hours of a quality read. And how do they look...
The Adventure's Guide is going to be my favourite source of in-game information for years to come. All thieving bonuses, all class/kit features, spell progression, etc etc etc. They're there, updated with the newest information and offering the real advice about how the game works. And no, there're no longer unrelated facts, only useful information (for example, it reads clearly that Wisdom grants additional spells to only clerics and druids, and I personally saw at least 5 threads on these boards with questions about this one thing).
And this guide now completely looks like a D&D book, with good-looking sketches and tables.
The Field Report offers an insight into SoD characters, creatures, groups and legendary items. It has awesome illustrations.
If you're like me, if like to plan in details your character builds, if you like to constantly check how this or that stat work, use these guides.
Thank you, Beamdog, for these manuals!
