Eliminating the Cult of Kosmos
Putting an end to the cult requires you to slay your way up through the ranks of the various branches of the cult, acquiring clues along the way, leading to your next target. As you kill the minor cultists in each branch, they will provide clues to find the leader of their respective branches, known as a sage. Once every cultist of a branch has been killed, you can reveal the sage’s identity, allowing you to find them in theworld.The Spear of LeonidasEach time you kill a member of the cult, you earn a artifact fragment. These fragments are used to upgrade the Spear of Leonidas after you have completed the Memories Awoken quest. At the start of your journey, the Spear of Leonidas is what provides your four adrenaline segments. As you level up the spear, by defeating cultists and upgrading it at the ancient forge on Andros, you are able to use more abilities and heal while using them. Once you upgrade the spear to level 2 you can purchase tier 2 abilities. Once you upgrade the spear to level 5 you can purchase tier 3 abilities.
