Kena: Bridge of Spirits

There are a total of 12 Meditation spots that you need to interact with in the game. Along with the Rot, you really want to make sure you get most if not all of these as you progress through the game since they increase your health bar which you can certainly use later in the game. There is freeplay after you complete the game, so if you don't get all 12 by the time you finish the game, you can clean them up afterwards. For their locations (and all of the other collectibles in the game), please see the Collectible Guide found here.
