Perks I intend to use:
Conjuration (necromancy only)
Illusion
Archery
Stealth
Maybe a bit of 1H stabbing if it will work in Master difficulty (it works so far because enemy is busy fighting my companion or zombie and I've opportunity to backstab).
Probably Alchemy but no pure magic or melee, so probably not any armor perks, 2H, smiting, and probably not enchanting (not 100% sure) and definitely no destruction.
Clothes (no light or heavy armor).
Stamina - I'd say no Stamina? I suppose it would be useful for archery/1h but probably not enough to actually go and level this up?
Magicka - I've read that later on casting is so cheap you don't really need a lot of magicka. I can't verify this, being low level. On the other hand, I see some people going Magicka only.
Perhaps spells are super-cheap for those who use Destruction almost all the time, with destruction items. Since I will need to combo Conjuration, Illusion, probably a bit of Alteration (along with bow/dagger) - having 1-school-cost-reduction item isn't going to help that much.
Health - Most of the time (except when getting close to stab someone) I plan to keep distance. I understand health is less important, but right now I'm already at the point where most enemies 1-2 shot me. To be honest, this isn't enjoyable. However, I am not using any protective spells yet. How much do those help?
What would be a healthy balance here?
