This quest is even possible to do without lockpick on highest lvl ?

There's a key to the cabinet in the Abbot's room I think, and there's a way to get the keys to his room as well. I honestly can't remember how though

[Hollywoodb1]

Yes. there's at least 3 ways to get it, including picking the lock outright

I leveled up my lockpicking skill by robbing the whole monastery + had a potion that adds +5 to said skill.

Yes, become a Monk yourself and get it /kinda" legally.
You have to do the scattered Pages Quest, but theres a Guide for it in the "full achievement and Quest help" guide

You have to steal they Key from the Prior, then you can enter without problem.
And yes, the key for the books is in the Abbots Room, the one next to his bed room (in a cabinet, if i remember correctly)

but Brother Librarian has one too.

Oh yeah i forgot: if you wanna do the "libri Prohibiti" Quest, you should not do the Restless Spirit one before! They'll notice that a book is stolen and the Medicine Book willbe gone...

I had it on me when one of the circators put me in solitary and it got confiscated, does that mean it is now gone from the game world and the quest that needs it is impossible?
