Darkness

From AmtWiki
When the sun goes down, it gets dark. Really dark. While Vampires and Werewolves have little fear of the gloom, humans and other mere mortals have to import their own light or end up lost - or worse.

It is dark inside an ancient crypt. Really dark.

Areas of Darkness may be marked with black ribbon, or the entire playing area may be designated Darkness. Optionally, any portion of the playing field laying wholly in shadow (from trees or other object or structure) may be called Darkness in a given game.

Players must keep one foot on the ground at all times in an area of Darkness Doing otherwise will result in a leg wound (player’s choice of leg).
Players within 20’ of a Light Source may move normally.
Line of sight is limited to 20’ inside an area of Darkness. This is the maximum range for spells and projectiles as well.

Undead, nocturnal creatures, and some others (Dwarves, Elves, etc.) may be immune to Darkness. Reeves may make any final ruling on which Monsters are immune.
