Ascension (Final Fantasy XV)

Ascension is a skill tree advancement system in Final Fantasy XV comprised of several trees called Astralspheres, which contain nodes that unlock abilities or enhancements.

AP is used to unlock most nodes. Red nodes are unlocked during the story and do not require AP. Green nodes represent ally Techniques, which can be equipped and initiated by the player in battle. Yellow and purple nodes represent other abilities and enhancements, with yellow favoring combat abilities and purple favoring passive effects and boosts. Each Astralsphere starts out at an empty central point between the starting nodes, marked by a point of light and connecting lines out. Unlocking a node makes immediately connected nodes available.

AP is shared between party members and Astralspheres, allowing the player to spend it however they choose. Learning an ability on the Ascension for the first time earns the New Power achievement/trophy. Activating twenty nodes yields Self-Improved, and activating fifty yields Self-Mastered. Ascension progression carries over if the player uses chapter select.
