Killing the higher lvl setians, ie sand strutters and scouts, yeild setin ears on a one for one basis, turn in 20 of these and you get a golden tuneing fork, no idea what it does though, it is just a piece of loot that cannot be sold traded or put in bank.
We killed this guy with 3 people, a 44 sorc, a 46 cleric and a 50 paladin, he didn't give any experience. I'm not exactly sure why, was dissappointing that a 5 minute encounter left us with a total of 3 gold... He heals if you don't have constant melee on him, so be warned. Seems to be fully immune to magic too, from what I saw.
