The caster learns the ambient lighting level that their body is exposed to. If his body is exposed to multiple at the same time, he learns only of the one that has the greatest amount of area. This spell also updates the caster as lighting levels change. Lighting levels are as follows: Darkness, Shadowy Illumination, Full Torchlight, Bright light, and Full Sunlight; the latter three have no differences in game effect except for creatures with light sensitivity (further rules for lighting will be given in the Book of the Wilds). This spell may be imbued into a Glyph.
