In Rooms, replace the following bullet point “A Dark or Lit state, which is Dark unless otherwise specified” with

A list of light sources in the room. A Room is said to be Dark if this list is empty, or Lit otherwise.

In the rule Flashlight, replace “a Room is Lit if this Item is in the Room or is held by an Explorer that is in the Room.” with:

a Room has a light source of Flashlight in addition to its other sources if this Item is in the Room or is held by an Explorer that is in the Room.

For each room that is currently Lit at the time of this rule being enacted, add Sconces to its light sources.

If We Don’t Need No Stinkin’ Room Types was enacted, the rest of this proposal does nothing. Otherwise:

In Rooms, modify “Every Room Type has Characteristics, which act as default settings for the items, dark/lit states” to:

Every Room Type has Characteristics, which act as default settings for the items, any light sources

In the Types table of the same rule, replace Lit with “Lit by Sconces”.
