Five types of collectibles are hidden throughout Oros, resting on high cliffs, deep inside caves, underwater, or behind weak walls. Keep an eye out for these items as you explore the environment. When you get within range of a collectible, the blue icon appears on the mini-map. A small triangle above or below means the item is higher or lower respectively. These pieces give you various XP when collected, except for Spirit Totems that add a +2% XP bonus for each one. Check the Collectible Cave Wall on the left side of the cavern just behind Takkar’s bed to see how many of each you have found.
