A huge thanks to bobbyfails for helping me with the locations of the 4 Urns. There is 1 in each chapter. For some reason, only 2 of my game captures were available. So I will include text based guides for the remaining 2 until I can sort this out.
Make sure to watch the ash blow away or it will not count. Thanks DylanXBAChapter 1
Chapter 2
Chapter 3
As you progress through the caves, you will enter into a huge cavern with a stream running through it, and a bridge directly in front of you. Cross over this bridge, and instead of turning left to continue the story progression, turn right and head in a straight line and you will see the urn on the floor in front of you a short while down this path.
Chapter 4
After leaving the cave at the beginning, follow the path around to the right and you will soon come across a sandy beach littered with candles. You will also notice wooden lines at equal intervals. If you walk along the beach with the sea to your left, the 3rd partition will have an urn at the back up against the rocks.
If you have any issues regarding my guide (except the lack of video) let me know and I will adjust it.
Thanks again to bobbyfails for the help. This guide would not have been possible without your help.
