If you are small race, I recommend heading to Dawnshroud Peaks (go to near the Sanctus Seru zone) and kill Lightcrawlers. There are 5 armour quests for the shells that drop. The vambraces are AC11 Dex4 Disease4, and are quite easy for a cleric to obtain after around lv 30.
Check the write-up of the quests for details...
