Just when Sunraku starts implementing his totally-legit-not-at-all-cheese crystal scorpion destruction strategy, something new shows up.
The new rare monster is insanely OP! Offense, defense, and regeneration all in one package. It looks like the devs really, REALLY don't want you farming crystal scorpion materials.
In the middle of all this, we get a sneak peak into some SLF lore. The Gold Scorpion uses the moon to regenerate. The moon was also a major part of the Wethermon lore. It makes me wonder about other Colossi, like how Lycagon only appears at night.
During the battle, Sunraku finally gets his prized crystal scorpion stinger from the new rare Golden Scorpion! Huzzah!
Even with that lore epiphany, this is mostly just a combat episode. The whole, "I can only travel to the inventoria a limited number of times" seemed like a pretty dumb and unnecessary limitation added just to increase the tension a bit. But I'll let it slide because the "oh no, now I have no weapon" actual limitation was both a surprising twist and a really good climax tension builder.
Can't wait to see Bilac's face when he shows up with the Gold Crystal Scorpion parts!
