O.K. I've clarified a bunch of that. Two things- I guess I'm still not really getting how backpacks work, but if I'm wearing one that's carrying 4 Enc the total to me is 7 Enc? Doesn't seem right according to cheat sheet but then again that's not the same thing as the book
. What's confusing me there is that the Enc for the backpack is 4 (3 if worn) then, on cheat sheet at least, it says a backpack reduces encumbrance of items within them as well.
And yes, firewater is liquor (and not for pansies, either!)
