[Darkness](Darkness.md) and other effects that obscure vision can prove a significant hindrance. A given area might be [Lightly](Lightly%20Obscured.md) or [Heavily Obscured](Heavily%20Obscured.md). In a [Lightly Obscured](Lightly%20Obscured.md) area, such as [Dim Light](Dim%20Light.md), patchy fog, or moderate foliage, creatures have disadvantage on Wisdom (Perception) checks that rely on sight. A [Heavily Obscured](Heavily%20Obscured.md) area–such as darkness, opaque fog, or dense foliage–blocks vision entirely. A creature effectively suffers from the [Blinded (C)](Blinded%20(C).md) condition when trying to see something in that area. The presence or absence of light in an environment creates three categories of illumination: [Bright Light](Bright%20Light.md), [Dim Light](Dim%20Light.md), and [Darkness](Darkness.md). [Bright Light](Bright%20Light.md) lets most creatures see normally. Even gloomy days provide [Bright Light](Bright%20Light.md), as do torches, lanterns, fires, and other sources of illumination within a specific radius. [Dim Light](Dim%20Light.md), also called shadows, creates a [Lightly Obscured](Lightly%20Obscured.md) area. An area of [Dim Light](Dim%20Light.md) is usually a boundary between a source of [Bright Light](Bright%20Light.md), such as a torch, and surrounding darkness. The soft light of twilight and dawn also counts as [Dim Light](Dim%20Light.md). A particularly brilliant full moon might bathe the land in [Dim Light](Dim%20Light.md). [Darkness](Darkness.md) creates a [heavily obscured](Heavily%20Obscured.md) area. Characters face darkness outdoors at night (even most moonlit nights), within the confines of an unlit dungeon or a subterranean vault, or in an area of magical darkness. ### Vision Types - [Blindsight](Blindsight.md) - [Darkvision](References/Terms/Vision/Darkvision.md) - [Truesight](Truesight.md)
