Dwarves and Half-Orcs have darkvision—other races need some form of light to see by
Light Sources and Illumination
INCREASED = Area in which light level is increased by one level (dim to normal, normal to bright, etc.)
Creatures with low-light vision (Elves, Half-Elves) can see objects twice as far away as the given radius.
Characters with Darkvision (Dwarves and Half-Orcs) can see lit areas normally as well as dark areas within 60’. A creature can’t hide within 60’ of a creature with Darkvision without invisibility or cover.
A candle cannot provide normal illumination, only dim illumination
Dancing Lights (torches)
Daylight is a bright light
Bright Light: All characters can see clearly. Some creatures may take penalties if in bright light due to blindness. A creature can’t use Stealth in an area of bright light without cover or invisibility. Daylight is bright light.
Normal Light: Functions like bright light, but creatures with light sensitivity do not take penalties. Examples include torch light, under a forest canopy in daylight, within a Light spell.
Dim Light: A character can see somewhat. A creature in dim light has concealment (20% miss chance in combat) from those without darkvision or the ability to see in darkness. A Stealth could be made to conceal oneself in the shadows. Examples include moonlight, bright starlight, standing 20 to 40’ from a torch.
Darkness: Creatures with darkvision are effectively blinded. Blinded creatures have a 50% miss chance in combat (due to total concealment), loses any Dexterity bonuses to AC, takes an additional -2 penalty to AC, and -4 to all Perception checks relying on sight and on most Strength and Dexterity skill checks.
