We are still in the early stages of the game here so I am willing to experiment with how to track things like spell lists. One option is that you can just update your spells prepared in the Rogue's Gallery any time you change your spell list. Another way is to list your spells prepared for the day in a spoiler block at the beginning of each new day, then update that with each post in which you cast a spell. This method would probably be easiest for me to keep track of things. For the time being, I will let each of you decide how you wish to do it, but pick one method and stick to it for now. Post here to let me know how you will be doing it so that I can know where to look if I need to know your spells prepared at any given moment for any reason. After we have been playing for a while, I will decide whether I like one method better than another or not. GlassEye, if you were to simply keep a running tally of your power points in the title section of your post, that would probably be easiest for me. Obviously, you would only need to note it when it changes.
Deuce Traveler, most of that stuff should be readily available in town. You'll have to make a Gather Information or Knowledge (local) check to find a shop however. Or you could ask your host if she knows any places. It might be a good idea to get some details of the place you are traveling to before you go, such as how far away it is, what the land is like, and so forth.
