Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

could we get a feat that can Copy Books the text fro mone Book to another so it works to open door in the Troll Mine?

If this is the spirit troll mine - no it would not be appropriate

The lore around these books implies acquiring a copy originally held by the assassins of the mine who made maps of old routes towards the upper dark and recording this in the books

(The implication lore wise that each breakthrough is to locating new tunnels not previously explored - rather than a rinse and repeat scenario)

Ooc the idea was to make each exploration slightly different and total exploration on single run rare

but you need to open a door that is odd to odd normel it is a key or a spell that open the door, a book come on it could have been much better made you lose a book to open a door???

Yes probably

The door represents a new route rather than a specific door. A book was chosen as was described above it does not open the door but the contents explain a new way through (this is represented by the door allowing passage) and the book does not get used like a key or magic.

I lose the book went time i past the door that is why i ask yo copy it and make it work iam not sure we talk about the same

A book will only work one time that is intended.

but no one will use that abandoned mine anymore
