Light

What lurks just outside the halo of your torchlight? In the sunless depths, a candle is the difference between life and death.

There are three levels of lighting while exploring dark places: bright, dim, and dark.

Bright light

If you are holding a light source, you benefit from bright light. Bright light means that you can operate without penalty.

If you’re holding a light source, you’re always clearly visible. Hiding is impossible.

Dim light

Even a little light offers hope in the darkness. If you aren’t carrying a light source (while someone else in your guild is), you’re considered to be in dim lighting. Any complex or visually-dependent task—such as picking locks, surgery, investigation, crafting—suffers disfavor on tests of fate while you are in dim lighting unless an adventurer with a light source actively provides illumination.

If you are in dim lighting, you may attempt to hide behind cover.

Darkness

No matter how accomplished an adventurer is, darkness is crippling. You are Blind while in darkness. Most activities are simply impossible to accomplish in the dark—others may be attempted but suffer disfavor.

Crawling in the dark is a futile pursuit. The guild is at risk of every pitfall and every trap, and creatures accustomed to darkness will find them easy prey.
