Monarch-level young pets are different from those at servant and warrior levels. The probability of encountering such soul pets in desolate areas is not high, and even if one does encounter them, one has to weigh whether they have the strength to capture them. After all, young pets generally have "guards" protecting them. Even if they aren't their parents, they could be some of the powerful soul pets within their parents' territory.
Most servant-level soul pets are wanderers. The number of servant-level soul pets is extremely huge, forming a massive foundational structure at the bottom of the Soul Pets World. Most servant-level soul pets choose to reside within a certain territory, following the orders of stronger soul pets.
Servant-level soul pets often die, but their reproduction rate is far greater than the proportion of their combat power compared to higher-level soul pets.
