A new trailer has been released for Tales of Arise, revealing some additional details on the game’s characters and showing some more short combat sequences.

According to the trailer, Renans can use Astral Artes, which use Astral energy that resides in all life and things. The Fire Sword used by Alphen also uses Astral energy, but he is the only one that can wield it, as the sword burns the wielder and he doesn’t feel pain.
