For instance, say an elf is holding a lantern with a 30' light radius (low light vision means she can see 60') and a human is standing 50' away from the elf, the elf can see the human but the human cannot see the elf?
But anybody knows you can see a light source for literally miles. So I would assume the human cant see any details, maybe not even see the elf, but surely they CAN see the lantern?
Is there a rule for this? Because it sounds incredibly daft if not the case.
in 3.5 book the Underdark,is stated that light source can be seen at 20×radius with DC20 spot(perception) and auto detected at half that (10×)
so lantern(30ft bright illumination) is
DC 20 at 600ft
DC 10 at 500ft
DC 0 at 400ft
DC-10 at 300ft
maybe double that distance for someone who has low-light vision?
