Spellbooks (Objects Help)
A wizard who wishes to cast a spell must have a spellbook. Wizard
trainers will always give one when one joins their profession; however,
other professions may also obtain them from certain trainers by just
typing: 'request spellbook'. If you no longer wish to have the spellbook
with you, just 'forget spells' to get rid of it.
As you travel through the world, you will come across various places
where you can get a spell; usually this is associated with completing a
mini-quest. The first time you complete the quest, the spell will be
written in your spellbook; any subsequent time you will just receive a
scroll with the spell which you can trade to other players.
Each spell has its own help file which you can read by typing
'help spell <spell name>'.
