Example Light Sources
Even though many dungeons are adequately lit, the cautious adventurer brings a torch or a sunrod when venturing into a cavern or an underground complex.
Common light sources are described in the Light Sources table. Assuming nothing blocks a creature’s view, the creature can see most light sources from at least a quarter of a mile away, and it can see exceptionally bright sources from up to a mile away.
|Bonfire||Bright||20 squares||4 hours|
|Campfire||Bright||10 squares||8 hours|
|Candle||Dim||2 squares||1 hour|
|Fireplace||Bright||5 squares||8 hours per load of fuel|
|Forge||Bright||2 squares||8 hours per load of fuel|
|Lantern||Bright||10 squares||8 hours per pint of oil|
|Phosphorescent fungi||Dim||10 squares||Ongoing|
|Sunrod||Bright||20 squares||4 hours|
|Torch||Bright||5 squares||1 hour|
Brightness: Most light sources provide an area of bright light around them.
Radius: A light source illuminates its space (or a creature’s space if the creature is carrying the light source) and all squares within the stated radius. For example, if a character carries a torch, bright light illuminates his or her space and 5 squares in every direction.
Duration: Most light sources last only so long because they require a fuel source.
