Luna is the new character in The First Descendant
THE FIRST LAUNCH OF DECENDANT | Before you play!
The First Descendant 1.0.5 patch is live and the massive update introduces a new playable character, Luna, and also adds a new skin for an existing Ultimate Descendant. Before turning into a playable character, she was an NPC, but now with her name part of the Rooster, this new character is set to bring some of her own skills to the pool.
However, while players are happy with her appearance and personality, they doubt her ability to make any contribution to the battle since her skills are more support oriented and players don't think the game needs more characters like this.
Luna's skills are designed to enhance the abilities of her allies, making her yet another supporting character in The First Descendant.
