You feel like you have to.

It seems a little stupid to take the deal, but who are you to argue with an oracle. "The book plus 1000 gold." You say finally.

"Done." The figure says so fast you know you should have said 10 times that. But a deal is a deal, the two of you cautiously trade powerful magic, each clutching onto your new prizes once finished. The figure then says, "Thank you." Then casts a spell and steps through a portal.

Looking at the sack of gold you smile and say, "Now to get a gun finally, a chunk of lead to cast my spell to make bullets, and find an inn to study the book."

Finding a gun proves to be far easier than you had imagined, as you seem to have fleeting memories of this town, almost as if you grew up here but just haven't been here in a while. Thinking about guns reminds you that while there is a nice store where a talented smith makes all sorts of old west style guns, you have your heart set on something a bit more modern if at all possible, so instead you go to someone said to specialize in other worldly weapons, and as your magic can make ammo it should be just fine. Not to mention It seems silver is the primary currency at 20 per gold so you find what you want as soon as you enter the little store. You drop 800 gold on a rifle, a tiny backup pistol, and a cool folding knife. You are pretty sure the rifle is an excellent copy of an old soviet bolt action rifle, it holds 5 rounds of .30 cal ammo and can be loaded by stripper clips of 5 or one at a time. They had 3 bullets so you should be fine making more. The little pistol is pretty sexy, the metal is sort of dull grey with black wood grips and stamped on the side as impossible as it seems for it to be here is "Colts patent 1903 .32 pocket hammerless." It has a total of 3 magazines, each holding 8 rounds. They didn't have any ammo but you are pretty confident you will be okay, your mental image of .32 acp ammo seems strong for some reason. A sling for the rifle and a little holster up under your dress for the slim pistol, on a hidden belt at places the gun at about the 4 o'clock position and the magic armored dress hides it well. The knife goes on the same belt on the front with a clip at say the 1 o'clock position.

Feeling ever so slightly more protected you then go buy a small magic leather backpack that they say will hold 80 lbs without getting any heavier and 4 pounds of lead for the spell. This, some food and cleaning supplies for yourself as well as the weapons leaves you with 55 gold and 11 silver and a room to sleep in for 3 days. You also discover a portal out of hell is 100 gold, so if you need to buy it you will need a bit more money.

Then with a bottle of wine in hand you sit at the little desk in your room and open the book. The text grabs hold of your mind and you don't leave your room for a month while you study, spending another 25 gold on food and lodging in the blink of an eye. Finally the month is over and you slap the book closed, as you do it bursts into a brilliant blue flame which rises up into the air transforming into a sparkling cloud that swirls around your room before your head rolls back, you mouth opens, and you suck it all in.
