I can't find the dwarves with the keys. I've hit every cave/tunnel multiple times, gone to the end of them, spammed Z as I ran through them, and I lit all the lanterns so I can see.

I still haven't found any more dwarf bodies after the first one, and I can't see in this stupid mine even with all the lanterns lit.

I took a week break from this game because of this quest. Coming back, I'm having the same problem.

Did you try using a Cat's potion as well?

Yea, I still can't find any dwarf body.

Cat helps immensely in that quest.

There are a bunch of doors, and you might get turned around and think that you've gone through all the doors when you haven't. That was where I went wrong when I first did this quest--I thought that the door I needed to go in was the door back out of the mine.

Not to mention that at least one door is immediately to the side when you enter the room, so it's easy to completely miss it. Best of luck... there aren't any other quests in the game that are like that, for what it's worth.

How many keys did you actually find?

There are 3 keys + 4 journals and they are on the shining bodies of the dwarves. They are at the far end of the tunnels. To make it easier just light the oil lamps around the caves so you will know where have you been and where you did not ^^ also use your map.

Oh,I just read the OP more carefully.So,you should have 1 key if you found just one body.
Look where my cursor is pointing,if I recall corectly that's where you should be going.The red squares are the locations of bodies that have the keys on them.Not really sure about the top end location,did it by memory,sorry.You also have the whole map discovered,that should help you,too.

I found the caves too dark as well, so I simply turned up the brightness and gamma a bit for that section. I simply cannot stand the "thump, thump" that constantly plays while using the cat potion. I could probably turn off my sub, I guess...

The tip about lighting torches to see where you've been is a great one.

I used no potion, lighted the torches to check where i went... profit.

The annoying part there where the team mates, they would get in my way all the time lol.

there is no way you have gone to all the tunnels, as they are locked by different keys. I am baffled by the fact that you are lost. the quest was very very well/nicely designed. cave 1 you find key to cave 2, where you find key 3 etc. I don't get how you are lost.

follow the keys, they are all on dead dwarf miners.

I did the torches also, but then I opted for cat potion. the potion also allows me to find glowing bodies better. this is the only part of the game where I wish the cat potion length was 30 minutes.

Don´t forget to blow up the holes too for the other quest... i forgot the name XD, one is the Immortelle flower and the other is to blow up the holes.
