i used the tunic (twilight jacket) and legs (walkers legs) from the tracking and stealth quests.
i used the ring (ring of savant) and brace (bracelet of resillience) from the focus and resist spells quests i think, i cant remember where i got the ring.
i used the gloves from the healing quest. (gloves of safeguarding)
the arms were from the tactics quest i think. (arms of armstrong)
and the hat from the mage quest (Philosiphers hat)
every quest giver gives you something, it says on the quest before you accept it.
you can get a whole suit, its not bad but not great. the resists were low 30s.
i ended up needing some of the special amor tho, shadow legs, burglers bandana different ring/brace combo with +skill
