Thanks all for your help! I’ve played a bit more today and found the dungeon and got Rainer incapacitated lol. We also ran out of torches which was kind of stupid. We barely made it back but sold a lot of stuff. I’ve finally been able to buy the compass (and music crystal thing) which should help with navigation.
Behind the corpse in the dungeon is another locked chest but my lockpicks were used up. I tried “examining” and using the lock a few times and got a message we escaped a trap and after 3 tries it opened. Is it worth it to go back and give the crystal? I have no idea why I bought that thing for 80gp!
IS4, your map link unfortunately doesn’t seem to work…
The murder quest is solved now but I’ll hang around a bit until I can max out the combat skills like everyone suggests.
