I was fiddling around with the equipment list of a character (Psion//Warblade 1) I made for an upcoming game. Since I changed my weapon of choice from greatsword to glaive, I had some leftover cash. I went through the equipment list in the PHB, and still had some leftover. Out of curiousity, I paged through some other source books I thought might have some useful gear and managed to add at least some useful stuff to it. I then thought of asking you playgrounders, what are some of your favourite pieces of mundane gear? What should no adventurer leave home without? I'm particularly interested in stuff from outside the PHB, since there's a smattering of equipment in a lot of source books that's hard to keep your head around.
