I actually debated whether or not Volker should break Lubo's necklace at first. After thinking about it for a while, I determined that there was no better occasion to have Lubo's necklace break, while his confidence/skill level isn't as high as it will get. And no, I don't think saying that a character will be developed further into the story is a spoiler.
Also yeah, the way that Lubo's wearing his moon emblem is actually pretty unpractical for fighting. I have plans to change that, but not entirely sure WHEN that would happen.
