This time we’re taking a look at the My Little Sister (4) quest, which has you gathering a blue crest.
Generally, you can use the collection records option – visible from the Start menu – to find which age items can be collected in (you have to be in the guild hall to see it). The problem is, if you’ve never scavenged the item before the records menu is useless. Worse yet, your Tenko will not be able to collect items on a scavenger run that you haven’t previously found in the world. In other words, you need to actually pick up a blue crest before you can take advantage of those perks.
The blue crest must be severed from a Astrapteryx. There are a lot of different missions that have you fighting an Astrapteryx, but the first time you’ll encounter it in single player is chapter 5. I recommend playing Break the Barrier – Part 1 mission which has you fighting a Astrapteryx in the Age of Peace. That being said, any mission where you fight a Astrapteryx will do.
Here are the other quests in the series:
