Spinning Rotor
Although it's nothing like the weapons traditionally used by knights in Lumopolis, Leyn, who cares more about a weapon's practical use than its looks, doesn't mind it at all, which reflects his character more or less... Leyn can infuse Luminatics into this weapon to make it continuously rotate, accelerate, and activate a switch to make Lumina gush out to destroy his enemies.
Fiery Blitz
Passive
Leyn's Normal Attacks gain a damage bonus of up to 50% based on his Zeal, the higher the Zeal, the higher the damage bonus. When Zeal reaches 100, he enters the Overzealous state and cannot use Normal Attacks.
Zeal: Each Normal Attack grants 5 points, up to 100 points.
