Nightvision

Nightvision is a term used for races who can see in the dark. Wolves, Elves, Arachnids, Kobolds, Orcs, and Dwarves all have this ability.

Otherwise, people need things that give off light, like a Lightening Ring, Glowing Ring, Shining Pendant, or a Phylactery of Moonlight or Sunlight.

Areas that need you to see in the dark are: Sewers, The Dungeon, and the Catacombs. The Catacombs requires 2 forms of light, so a Sunlight Phylactery may work, or Nightvision + a Ring, or 2 Rings without the ability.
