Darkvision in Low-Light


Rules Questions


So there is probably a thread about this already and I'm just missing it. When a character is in a situation that is low-light, but has Darkvision does that mean they have a difficult time seeing in the reduced amount of illumination? I ask because there is a race (Syrinx) that have both Low-Light Vision and Darkvision. I always thought that with Darkvision came the ability to see in low-light conditions.

If possible I would appreciate the cited page (we have players that love to argue about rules they don't like haha)


You can see in low light up to the range of your darkvision.

Low light vision has longer range than darkvision...generally.


darkvision can't see color, so you can't see color or stuff like that in your darkvision range that isn't covered in your low light range.

Plus lowlight with a light source will see further than their darkvision range.

Low-light vision and Darkvision are completely independent of each other. There is no interaction.

A creature with Darkvision can use it even in light.
A creature with both uses whichever is most advantageous at that given distance.

Example: Creature with Darkvision and Low-Light vision is using a torch (normally: 20' normal, 40' dim).
They can see in full color out to 40'. (2*20')
They can see in black and white out to 60' (darkvision)
They can see from 45-80' but creatures have concealment (2*40').

Combining these we have: normal vision to 40', darkvision from 45-60', dim lighting conditions from 65-80'.

This is not entirely accurate.

Normal vision in the most common situation (torch or light spell) = 20' normal and 40' dim.
Low light vision in the most common situation (torch or light spell) = 40' normal and 80' dim
Darkvision: 60'

So, while the low-light vision has longer range based on a torches range it is not as effective as darkvision in the 45-60' range.


They are completely different things. A creature with lowlight vision can see twice as far in areas of dim light and retains the ability to see color. How far they can see is dependent on the light source. Darkvision allows you to see in black and white for a set range.

So a creature with both would take the more favorable circumstance. So if the creature had both and was carrying an everburning torch they would be able to see clearly for the first 20’ and also see color. They would be able to see from 20’ to 30’ clearly in black and white, or dimly in color. The would also be able to see up to 80’ dimly in color.


I understand all of these things. The main thing I am trying to figure out is, if you only have Darkvision how well can you see in Dim Light? Because with Low-Light Vision you are able to see clearly in Dim Light. You could read normally in Dim Light if you have Low-Light Vision. And I understand that if a race has both Low-Light and Dark they have no issue at all, but a creature with only Darkvision in an area of Dim Light. Are they only able to see clearly as a normal human would until the light ends and then they can see with Darkvision?


That's what I tried to answer above but maybe I should have added a few more points.

Darkvision has no miss chance in dim light unlike low light vision.

After the light ends they see with darkvision. In the dimlight section...hmm I guess black and white stuff perfectly, colour stuff like a normal human?


Yeah, the area of dim light is what seemed like it was a gray area (pun intended). So far we have been just going with the idea that you can see anything in range if you have Darkvision (all-be-it in B/W if there is no light) and have no issue with fighting and such. I suppose we will continue that unless someone knows of where it says other wise. It makes sense to me I suppose cause things that give someone Low-Light Vision instead if you Darkvision if you already have Low-Light Vision.

Low light vision has no miss chance in dim light as far as I know.

More accurately, it treats a larger radius around a light source as normal light (in which it takes no penalties), then treats another area that would be dark to a normal human as dim light (taking the normal dim light penalties.

That's what I thought until I saw the feat that has lowlight vision as a prerequisite that negates the mischance in dim light. Unfortunately I don't remember the feat name. However, look up dim light under vision and light in the core rules. It says 20% mischance unless you have darkvision.


Found it!

Ah I just reread what you posted. Essentially we're saying the samething, except I said it in a sort of misleading way.

The bolded statement is incorrect.

You seem to believe that low-light vision allows you to see in dim light normally. It does not.
Low-light vision doubles the range of normal light and doubles the range of dim light.

Example:
A torch has a normal light radius of 20' and a dim light radius of 40'.
A person using low-light vision sees normal light from that torch out to 40' (20*2=40) and dim light out to 80' (40*2=80).
