For those who are wise enough to build the required connection, the unfathomable wisdom and power of the celestial bodies can be attained by Communing with the Cosmos.
The Commune with the Cosmos function is available once a player reaches a certain level. At that point, they will be able to combine Star Runes found throughout the world in order to get valuable, permanent stat boosts to their character.
The Communion Abilities already acquired can be found in the Commune with the Cosmos menu. The more stars that are re-merged in order to achieve this communion, the more Star Runes will be required for the next added attribute.
