It took me almost two full runs through the dungeon to notice this shard. This is even more embarrassing when you find out where it is located. It’s just right from the entrance to the first large room. It is amazingly hidden, due to the fact that this is a rather small corner. In my defense, I can also add that the nearby Dwarven machines make a loud noise, so I couldn’t even hear the shard.
Find and enter Aldunz dungeon.
