Illuma-Swords

Illuma-Swords are lightsaber-like "weapons." Illuma-Swords are put on display in Ninjago Doomsday Comix by Rufus MacAllister.

Child's Play
Rufus informs Lloyd that Illuma-Swords would work well, as the Grundle is nocturnal and its weakness is light, but the shop only gives them out as a prize for winning a comic book trivia competition. Later, Lloyd loses the competition (due to the final question being from a last-issue comic that had just sold out) and the Grundle shows up. The Ninja grab the Illuma-Swords to defend against the Grundle, but because they were meant as props and they break easily.
