Soul Stone (P-10) Only works for Blood Soul & Soul Spirit

Attention, Heroes of Cronus!

Eudemon Soul Stone is used to promote the divine phase of your eudemon. You should first prepare a Eudemon Soul Stone of the same phase before you find Aderes to promote the Divine Phase of your Eudemons. However, the Soul Stone (P-10) can only be used on Blood Soul of Vampire and Soul Spirit of Necromancer. Please note that Soul Stone (P-10) is currently not available to upgrade the divine phase of other Eudemons. We'll let you know if there is any change made on this stone.
