Investigations
Investigations are special quests that offer unique rewards and are unlocked through various in-game activities. These include finding monsters, capturing monsters (low, high, and master rank all count separately), talking to Villagers with a '!' in Astera, Research Base, or Seliana, and completing previous Optional quests. Randomly available Rare encounters that last for 2 quests and disappear also contribute to unlocking investigations.
Other methods for unlocking investigations involve fully researching monsters (all tabs in the monster manual) and hunting a certain number of different tempered monsters. For investigations with multiple tempered targets, only the first listed target registers. Your current progress level for Assigned Quests also influences the availability of investigations.
- "Special Arena:" Quests: These are unlocked by capturing the specific monster first. Once completed, they appear randomly on your Quest Board. Capturing a Low Rank Barroth, for example, will only unlock the Low Rank Special Arena.
- Rare Encounters: These include Zorah Magdaros, Xeno'Jiiva, and Shara Ishvalda optionals. Hunters should check their quest board as these only last for 2 quests total. A change in music in Astera/Seliana and a notification sometimes signal their appearance.
