Hi Larian Studios.
First of all I must say that I love this game! One of the best RPG's I've played (and I've been around since the NES era). Spot on music, dialogue and level design. Interesting skill trees and fun combat.
Now to my problem:
Before I finished Broken Valley and entered Maxos' Temple I felt extra adventurous and entered Oroba's Fjord. Much to my amazement I could enter the area and even kill the first goblins I encountered (resulting in a whooping 3900 xp from each goblin). I continued down the path, took the grand knight shrine waypoint, went a bit further until I encountered the knight in distress.
After shooting a few arrows on these goblins I noticed that they didn't lose any health at all. Thinking that this was a way to prevent me from continuing further in Oroba's Fjord at this point in the story I returned to the waypoint and continued my quest inside Maxos' Temple.
Today I conquered my Battle Tower and was at the point where I was supposed to go to Oroba's Fjord, but to my disappointment I found out that the goblins were still immortal!
Edit: I flew past them in dragon form and tried killing other mobs. Seems like it's ONLY the goblins that are supposed to fight the knight that are immortal. The knight on the other hand is standing further up the passage and are not in distress at all, nor can I talk to him

Edit2: The lvl 18 goblins near the waterfall cave gave me 2200 exp each, and I'm lvl 20! Waaay too much exp. I'll enter the cave and report how much the higher leveled mobs are giving.
Edit3: Lvl 23 skeletons and dragon elves are giving me 2400 exp each (I just reached lvl 21). Seems like something's off with the exp calculation here.
