Hi.
Thanks for the quick response. The first time I tried working my way back up they were still immortal, but after I'd entered the waterfall cave I could kill them again. I had lured a goblin chief and the knight all the way back up to the "Red Ore Alert" quest giver, but once I could kill the goblin the ran aaaaalll the way back to his original position so I could talk to him again.
The lvl 18 goblins were now giving me 300 xp (since I'm now lvl 21), so there's definitely something fishy with the exp gain.
