Illumination describes the amount of visible light that exists in both subterranean and wilderness environments. It is related not only to light sources available to creatures, but also to natural conditions related to weather and astronomical bodies. The effects of illumination, though mundane to most players, require exhaustive explanation, because light is fluid and difficult to quantify with regards to player imagination.

Light Sources

Light is produced through combustion, in the form of torches, lanterns and lamps, and through spellcasting.

Torches

These are the cheapest and most available form of illumination. A torch can be made using a strip of cotton, linen or woolen cloth that is at least 2 inches wide and 36 inches long, which is wrapped repeatedly and then tied around one end of a stake about 18 inch in length. For game purposes, a torch weighs 2 lb., 6 oz. The end is soaked in 1 ounce of whale oil or lamp oil, and sealed with 1 oz. of candlewax. This operation requires 8 action points (AP) to complete. A torch will last for 100 combat rounds. Afterwards, the stake can be reused, though it will lose 1 inch of its length with each use. A 15-inch torch will be hot on the face, whereas a 12-inch torch will feel too unpleasantly hot to hold for more than 25 rounds at a time. A torch less than 10 inches long will be impractical.

A torch dipped in lamp oil will clearly illuminate a radius of 6 hexes; a torch dipped in whale oil will illuminate a radius of 5 hexes. Torches may be put down, though they will sputter on a wet surface after ten rounds and go out; or they may set a dry surface ablaze over the same time (save vs. normal fire). If applied to paper or an airy fibrous substance, the save should be made immediately. A torch that has been laid down will illuminate a radius of only 2 hexes.

Torches produce double their illumination during full moonlight.
