Let's start off with the Rogue class. Obviously, the skills dealing with locks and traps are a must. These are the ones I'm aware of, their necessity being from top (top priority) to bottom (useless).
Open Lock
Search
Disable Device
Hide/Move Silently
Tumble
Use Magic Device
Other class skills, I'm not too sure about. I hear that
I don't know how many of you folks who play the Original Campaign (including MotB) use traps, so Set Trap is somewhat questionable to me. Sleight of Hand I've only seen one good use for outside of the Tutorial (as outlined in the Chpt 1 Walkthrough) so far. Listen and Spot I have no idea how useful they are for any class in the OC.
Oh, and on a slight side note, 2 questions:
1) Does anybody know of any Companions who have Craft (Alchemy), Craft (Armorsmithing) or Craft (Trapmaking) as initial skills (as in they have points in them before you allocate skill points on level-up)?
2) Asides from possibly making something to be enchanted, the Craft Magic Arms & Armor feat doesn't require the use of one of the crafting skills itself to make magic gear, does it? I figured it'd take a separate workbench as well as just the item, some experience, a spell and some components. Am I correct (on the assumption of "No Craft skill required for magical crafting")?
Honestly, I am familiar with Core 3.5 rules, it's just a few of the actual implimentations in NWN2 that leaves me puzzled.
