What are Shrines? And where do I get them?
Shrines are a special dungeon decoration that can only be found in special shrine dungeons.
These special shrine dungeons are spread all over the world and can be identified by their name and the loot. They are always called "Shrine to..." and if you open the loot tab theres a second line showing the shrines you can loot if you are lucky.
You can visit these dungeons as often as you wish to loot all of the available shrines.
Why should I go for shrines?
Shrines offer blessings, which you can use for a fee of 10 platinum. This even gets cheaper through archievements when you use a certain blessing often. To use them you need to place the shrine in your dungeon and then reload the game. After that a blessings choose tab appears everytime you enter a dungeon.
There are various shrines available, with different blessings and lookout. Last but not least they make great dungeon decoration too. You can change their teint like on all decoration items of course.
As it would count as spoiler to give exact locations I post some directions in which regions its worth to search for shrines. If someone knows another one he might reply and I´ll edit it in here. Most shrines are level 15 so make sure to have the needed Knowledge or Survival skill.
