About

There are many possible ways of observing your surrounding, but audiosense, lightsense, gravitysense, magnetosense, olfactorsense and sonarsense are best known. Out of these, lightsense (which is what humans term sight) is by far the most common, but its notable that ronites use magnetosense.

The ability to see things relies on 4 possible things:

1. ambience of the right type for the sense (having light in the case of lightsense)
2. signal (contrasting, non-camouflaged object in the case of light, or things making sound in silence in the case of audiosense)
3. clarity (lack of things blocking the sense, such as mist, dust or foliage in the case of light)
4. emission (carrying a torch in the case of light, emitting a sound in the case of sonarsense)
5. accurity or the degree to which you have the sense.

You might be able to see from the above that emission is similar to ambience: emission is bringing ambience with you. It might also be claer that sonarsense is the same as audiosense, except the first has a built-in emission component.

Ambience

However the ambience is gained, there are 6 levels (explained in terms of lightsense, for easier understanding, but this applies to all senses).

Blinding

Blinding ambience is light so bright that it can damage your eyes with long exposure and your lightsense range is reduced to a quarter. This is denoted 0.25(field,rad) in lightsense and magnetosense. A sudden exposure to blinding ambience means that you must make a sv Perception or be blinded for d4 rounds.

Bright

Bright ambience is the equivalent of a glary and and cloudless day. This is denoted 0.2(field,rad) in lightsense and magnetosense

Full

Full ambiance are conditions that are well-lit, without being uncomfortably bright. This is denoted 0.1(field,rad) in lightsense and magnetosense

Dim

Dim ambience is the equivalent of the half light of dawn, dusk, a dimly-lit room, or night under a clear sky with a full moon. This is denoted 0(field,rad), and your visual sense range is reduced to a quarter.

Dark

Dark ambience is the equivalent of night on a moonlit night. This is also denoted 0(field,rad), and your visual sense is reduced to a tenth.

Black

Anything equivalent to underground with no light source.

Obscurity

Obscurity is the lack of clarity. There are two levels of obscurity (again, explained in terms of lightreception)

Light Obscurity

Meaning that vision is hampered by either dim light, a light pall of fog, smoke, or dust, or some foliage. Your visual sense range is reduced to a quarter. Perception checks that rely on vision are made at disadvantage.

Heavy Obscurity

Meaning that vision is not possible because of darkness or thick fog, smoke, dust, or foliage. Heavy obscurement produces the blinded condition.

Emission

Emission refers to a field of a type that is appropriate to your sense.
