Bombeta was a creation of Dr. Viktor that didn't work as it was supposed to. It had some evil features no one saw coming. For that reason, Dr. Viktor decided to work on a refactor: L1ght! This brilliant artifact is pure, functional, and loyal to the monsters who need its light.
L1ght is a solid Light denier with surprisingly great speed for his role, though let down by other features. One of his best gimmicks are his trait, which includes Artifact, a very annoying trait that ignores both negative and positive effects. His cursing effects are pretty good in accuracy reduction thanks to Blind and Daze as well as Light Weakness, which can provide synergy with strong Light attackers. His moves have generally low cooldowns, though their moderate stamina costs are a bit of a letdown. Though his relic slots are pretty good in Mask making up for his stamina costs while stamina draining and Armor protecting his glassy life, this makes him incapable of chain denial which is a huge problem as a denier.
Light attackers such as Zuperfox, Lightmare and Diegael get an INSANE boost from the Light Weakness effect, combined with their own self-boosts. (Pierce for Zuperfox, Double/Triple Damage for Lightmare, Taunt Hater for Katsuko, Villains Hater for Diegael). In fact, the L1ght + Katsuko combo could be used to destroy tanks such as Bombeta, Cryocrawler or Shelly.
Counters
Powerful Metal Attackers such as Vanoss2099 and Roboelf are a quick turn-off for him, especially with his terrible life.
Monsters immune to Stun in some way, such as Iguanazaur or Nahane, can ignore his form of denial.
Roost Waine is a great counter, as he have Dodge Area, enjoying that most of L1ght skills are AoE, he can also apply Control Immunity to his team, meaning L1ght denial is really useless.
