I got a question concerning the premade NPCs, because it seems like there are patterns to their spawns. When I am out on the islands, I almost always run into Dusk and Razor at some point. They turn up with much greater frequency than any of the other NPCs, and they're almost always together. When they're not together, they're wandering around the island alone rather than being in a group with other NPCs. Is there something to this observation, or is it just a coincidence?
What ive noticed is that when you give them certian clothing/equippables, there seems to be a certian "level". As in higher quality gear spawns them more towards the higher levels.
Ive tested this very briefly and found that giving your NPCs the "low quality" option gear/clothing will most likely spawn them around the Level 5 to Level 9 mark.
It might be deeper and perhaps everything has certian values that effect at what level your NPCs spawn, but from what i can tell its linked to what your give them.
