Unbreakable Spellbook

[JeminiZero]

2) a) How could you create a Spellbook that could not be damamge or would repair it's own dmamage?

As mentioned above, Complete Arcane has rules for making tougher spellbooks. It even has rules for tattooing spells on yourself. Its not truly unbreakable, but in the event your body is destroyed, the loss of your spellbook is the least of your concerns.

Unfortunately, there isn't must space on the body to hold tattoos. I usually try to have at least 1 spell of each level tattooed, so that in the event my wizard loses his book, he can cast *something*.

Besides that, you can try forging an air-tight box of Riverine to store your spellbook in. Riverine is from stormwrack and is virtually indestructable- even more so than adamantium. Its essentially walls of force but shapeable into mundane object, but its hideously expensive at 2,000 gp per lb. Such a box probably weighs 2 lb at least (since a semi-waterproof spellbook sheath weighs 1 lb) and will set thus you back 4,000 gp.
