I've played Skyrim before but mainly "powergaming" it, just focusing on dealing as much damage as possible and since I've powergamed with a warrior and a mage and because of that I would like to roleplay an assassin - I just want to make sure that the skills I choose doesn't mess up the balance in the game and that they also fit an assassin from a roleplaying-perspective. I've chosen to go with:

Race: Redguard

I just love Redguard so thats why - Race isn't that important in Skyrim, is it?

Primary Skills: One-handed, Light Armor, Archery, Sneak, Conjuration

Secondary Skills: Smiting, Alchemy

I've chosen Conjuration because I want him to have a dark magic skill and because he'll be able to conjure help, because as an assassin a follower is not just suitable.

Smithing is going to be the major crafting skill because I want him to be self-sufficient - he's a loner
Alchemy is not going to be spammed, just for creating healing potions and poisons.

What do you think?
