Thanks Urst, this I am afraid doesn't clarify my doubts.
I mean, I raised my lockpick skill to 30 or so, but now i decided to go with the trickster tree.
So, if i reach the memory ("adept locks"), those points i put in lockpicking are wasted? (except for the more gold looted of course)
What my real question is: if i unlock that memory, the adept locks are automatically unlocked, or only simpler to unlock, and i still need 25+ in the skill?
To find secret stashes i believe you are referring to "sleight of hand" skill.
Thanks man
