Point of Rat Focus (Important Focus on Rats from Important Points of View Orbit Menu for Regal Rats) (#71597)

Regal rats, while uncontrolled by players, are a point of interest
- They're the first monster to show up in an area that's otherwise empty
(in my case, a desert)
- There are no other monsters in the same biome as them
- They have a unique ability: they spawn chests when killed
- Their loot includes a rare drop
