I've been told that Mallapi is northeast to Gnaar Mok. I go to Gnaar Mok and the only thing that I can find northeast of town is shrine to some saint. So what gives? Where is it actually at?
Go to Gnaar Mok, cross the bridge onto the mainland then head directly north-east. The entrance to the cave is in the side of the mountain. Not very far. You should go between to swamps if you are heading in the right direction.
I've been told by Hasphat Antabolis that he wants a puzzle box in Arkngthand. So I go there, kill everything, leave no stone unturned, and still can't find it. A little help would be awesome
This gets a lot of people....whatever dev did this had a real sense of humour. Go back to the entrance of Arkngthand, go down the dirt cave bits until you reach the bottom. Look back towards the entrance, and instead of going towards the bottom of the of that structure, look a bit left and there is another dirt cave bit that go's upwards to the level above the structure.
