Tomes: Tomes are books that give updates to information. This could be an update to the lore section, faction section or information on a new quest in the futures. Although some will be blank, others will be worth the read.
Grimoire (Equipment): Grimoires is a mages best-friend. Being equipped with on of these allows you to reuse spells multiple times rather then the once per spell page. These can hold numbers of spells starting at 5 and then working there way up.
Weapons (Equipment): Weapons are well weapons. Should be easy guys.
Ingredients/Herb: For herbology and Alchemy these are essential and come in many forms from the monster you just killed to the purple flower described in the description.
Accessories: Rings, Necklaces, anything that can be worn.
Alchemy Journal: A Journal used to hold recipes. Very useful pre combat but due to time it takes to prepare symbols, or mixtures it's not handy in combat situations
Spell Page: A spell that holds information to cast a spell. Unless held in a Grimoire the page will burn up after use.
Recipe: Recipes are pages for Alchemy. Each holding information on a new formula. Recipes like spell pages burn up after use unless bound to an Alchemy Journal.
