When asking what we should do do you mean personalities of the characters?
If you mean my question, it's sort of a mixture. RAM's is probably the only character that has any implied personality to his abilities, but I'd like to make sure nobody gets anything completely useless or contradictory.
Also, do I need food? Technicly my guy eats souls, I can just find a rat if nessicary, or dead enemies.
Yeah, you need normal food and sleep and so on. It's a lot easier to normalize everyone, instead of worrying about all this odd trivia, like what exactly someone needs to eat.
However, in this particular case you do in fact eat souls. They're just not for regular sustenance.
ok change my cow to ..... A barrel of cheese? Do i need to change anything else? What skill should my book teach? like sorcery skill? or do you mean a book on woodcutting that gives me woodcutting bonuses?
Cheese is fine. You don't even really need to specify what kind of food if you don't want to.
I think you're misunderstanding what the book can do. The item you bring has to be a "tool," which is something that enables or improves a skill. An axe is a fine tool, because it can be used to chop trees (Woodcutter skill) or enemies (Axeminotaur skill). In order to count as a tool, a book would need to be used on something that a skill would likely cover. Since it's a book, most likely that'd be some sort of noncombat magic, like divination or raising the dead.
You also still need to specify a class of some sort.
