Heh, you can tell the spell heavy groups vs the hack and slash groups!
My first two times through I pretty much cruised through it and only rested when someone got tired... not as often as BG1.
Ended up being less than 100 for certain.
However, I'm no soloing an Elven Multiclass Fighter/Mage/Thief and since I've got the Planar Sphere and Fighter keep as my strongholds (I love having them both!) I rest a bit more often.
By the way, how long does it usually take for your apprentices to make something? They've been working for close to 4 days now and still casting their spell effects! GIMME MY WAND OF THE APPRENTI ALREADY!
