1) I try to use different classes every time I make a new character, but right now I'm using a jedi consular/jedi master
2) I use robes, I always found armor to be useless in KOTOR. I also equip anything that boosts wisdom and charisma
3) Dual sabres (blue and silver)
4) Force channel
5) I made my character completely reliant on force, because she'd get owned if she fought with a lightsaber without using and force powers. I use a lot of stat increasing powers and also use a lot of powers from the high level force powers mod.
PS: how do you get force enlightenment?
