Also I have been thinking of not using the rules for moon magic as it will not come into play very often. What I would like to do to represent the power Raistlin recieved when his health weas shattered and his skin chenged is make him an "overall specialist".
I would like for him to have the specialist benefits but no penalties, and in place he will have the following drawback.
Raistlin is only at his best health when he is "full" of magic. When he has casted over half of his spell levels in spells for the day he starts to suffer physically.
* -1 to hit and damage
* cannot run or swim or any other activity that causes exertion
* Str is considered 5 for opening doors and bend bars etc. Though he can still carry the same weight
* diblutatling cough (at 0 spell lvls) cough is so bad he cannot do anything but cough and move at 1/2 speed
The above drawbacks can be surrpressed for two hours by drinking an herbal tea special for his condition.
I think when Raistlin was a black robe he was "healthier" because he had more magic lvls and didn't go below half as much.
Note on magic levels:
As it is now Raistlin can cast two first and one second level spell. That is a total of 4 spell levels. 1 + 1 + 2
So when he has casted his second level spell and then one of th efirst he would be below half, and suffer the drawbacks above.
If he becomes what I am calling an overall specialist, he will recieve the following:
* May cast one more spell per spell level, i.e. three first and two second as a 3rd lvl magic user.
* +1 to saves vs all spells, and -1 to anyone making a save vs a spell Raistlin casts.
* +15% to learn a new spell
* auotmatically learns one new spell at each level
