Anyone know how to get Arks Badge: Pink?

In JP server, this badge drops when we use Rare Enemy Trigger with Exploration quests. These triggers make rare enemies appear for certain. But at the moment, it looks like we don't have any way to get these triggers, so I'm not sure how this works in NA

Ive had one of these triggers for a Raghbad in the Forest no idea where I got it and got one pink badge.
