Para Lux is the first nonhybrid, wild spawning legendary, but it won’t be the last. This thing has recently been made into a global anytime spawn, which is a very good move. However, its still a short range spawn. Given the global pandemic, winter, and other circumstances preventing people from going out and waiting for this thing to spawn with its 0.4% spawn rate, I think its only fair to allow it to be placed in sanctuaries.
I’ve been fortunate enough to unlock one, but I have the privilege of being able to go out without much worry in a mask and whatnot. Others are not.
If you’re worried about lower level players getting a legendary too early (why would you make it a wild spawn then?) then restrict FIPing legendary nonhybrids to player level 15 or something.
