Are there any stories about a 'Evil' witch who curses people, but removing the curse involves learning a life lesson? It sounds like some stories I've read, but i can't remember where.
Anyway my take on the skills:
[] Food Preparation (1)
[] Cooking (1)
[] Cleanup (1)
[] Haggling (1)
These are necessary for being self sufficient. Something many evil sorceresses have in common is the inability to take care of themselves, leaving everything to their minions.
[] Logistics (1)
[] Politics (1)
These are necessary for taking care of our lands and our people.
[] Swordplay (2)
[] Archery (2)
We need some way to defend our-self when magic is not an option, or at least in order to buy time to escape. Archery is preferable because it also allows hunting and spell aiming.
Normal Schools
[] Divination
Not very useful at lower levels, but it is cheap to master and can probably be used to gather information and possibly see the story we get ourselves caught up in.
[] Transmutation
Useful for self transformation, utility, disabling enemies without killing and useful for crowd control.
[] Blasting
Good for combat and some utility, but not something we need to be masters of at the beginning.
[] Glamour
It has it's uses but is more costly and has a weakness against animals unless we invest heavily in it.
[] Enchantment
Interesting to use, but to expensive to use and to learn and can only really be used to do effects we already know. It is also really expensive point wise which keeps us from learning other schools to actually take advantage of enchanting.
Something we have to pay attention to with the questionable magics is not only how we can use it, but how people will believe we are using it. Most of them can be twisted into something less evil, but that won't change how people think we are using it.
[] Life Magic
This is something we should avoid. It could probably be twisted into 'good' but the description states it feeds on suffering, pain, and death, which is really hard to explain as nice and will almost certainly be misunderstood.
[] Necromancy
This is questionable, but as noted it has good uses, even if they are willingly overlooked. We should probably invest in it a little, but it is not something we need to master.
[] Curses
It can be used for interesting things, and possibly combined with other schools to enhance them or make them more permanent, especially if we get creative. Also unless we get obvious about it's uses we can probably pass it off as parts of our other less questionable magics.
[] Conjuration
This is sketchy but can probably be used well if we figure out how to do it properly, but it would probably be looked down on by anyone who sees it regardless of if they were willing or not. Also using it runs the risk of being outsmarted by the summons until it gets mastered.
