The patch note for 1.1.6 is simple.
The side quest “A heart of water” is done in this patch. This quest has a good amount of lore related reveals. You will encounter one of the Gods.
The quest also pretty much concludes Ugi mine for the time being. It can be continued but, whether I will continue on, I don't know yet.
What has been added:
1. Ugi mine level 7 and 8 were added to complete the side quest. This includes 3 new monsters for the zones.
