I'm trying to develop a very self-sufficient solo build and I really love the Monk mechanics, so I'm thinking of creating a multi Monk/Rogue. The Rogue splash is partially for the SA but also for the ability to open locks. I don't really care about the disabling. You see, it really grates on me to be unable to find secret doors and open up locks to get into places, which is what eventually made me give up on my solo Paladin.
My question is this: is it viable to splash a single level of Rogue for my Monk to be able to open locks? I don't know if there will be enough skill points available to do that plus everything else I need (Hide/Sneak/Tumble etc), to get a solid solo Monk that isn't hampered by locks. Honestly, if it weren't for locks and secret doors, I'd be happy with a pure Monk. But being solo, I want to be as self-sufficient as possible. It's just that the INT investment seems to be build-breakingly high, in order to pull it off.
Is this do-able, or am I just going to have to tough it out with my squishy pure Rogue if I want to get into those places on my own?
