Now I'm playing Curse of the Azure Bonds.
The FIX option when in camp is quite handy.
Curse of the Azure Bonds
The "remember" feature is automatic. When you are in camp, press R and it will rest long enough to memorize the spells that have been used. If you want to change what spells you have memorized, press m and exit(intead of keep). It will then bring up the spell list and you pick which ones to use, that you don't already have memorized. You can cast and lose ones that you don't like. That way you can change what is in your spellbook.
When in doubt, kick your neighbors dog!
