I noticed the doors at the rockbottom Inn are those heavy big metal rusty looking doors. Wouldn't it be more inn like if they were the normal wooden doors?

Unless of course they are like that for a reason.

They're that way because we're in the Underdark, and wood (and even zurkhwood, which is mostly our way of getting around tileset limitations) is rarer than metal/stone.

ahh, i see.

shouldnt it make those wooden shields more expensive? ( there us a wooden, not zurkhwood, medium sheild)
