I'm still thinking Occult 5 is still a good idea.  You're eventually going to want/need a spell that calls for making an occult roll, and raising your occult score to 5 will take 16 xp, as well as umpteen training times.  Level 2 backgrounds you can get reasonably easy by roleplaying or spending 6xp (if the ST allows the incredibly common house rule)   Willpower will cost you 16xp as well, (assuming your stated willpower of 8 on your MDV is accurate) but you'll almost certainly see less tangible benefit from it, and it won't take you any training time to raise with xp.<br/><br/>Plus, what self respecting sorcerer only does the minimum amount of brain melting occult study to get a bachelor's degree in magic?
