OK, I am back:
I messed up above, sorry.
Here we go:
* Boost stats;
* Light / mage light;
* Bless / Bless weapon;
* Major Healing;
* Restoration;
* Neut. Poison;
* Life Keeping;
* Life Giving
* Divination (skill, but I consider a spell in my game);
* Mage Armor/ Treeskin;
Exclude any kind of offensive spell or spell that can be tactically effective (i.e. sleep, calm...)
Include any "bonus givving spell".
Basically will be natural to be a great suport with the guidelines above.
Best regards, and sorry for the hurry.
