-Brass lanterns are more expensive and heavier than lamps: though charging sources are generally lighter in comparison to the [[potions of oil]] required for [[oil lamp]]s, they are much rarer and more costly themselves. Either type of lamp is preferable in comparison as a long-term light source, though a brass lantern is still useful in the short term if a [[hero]] comes across one.

 A lantern is a source of lighting that is often portable and typically features a protective enclosure for the light, making it easier to carry and hang up as well as making it more reliable while outdoors or in drafty interiors; lanterns may also be used as torches and as a form of signaling. Historically, the light is usually a candle, a wick in oil, or a thermoluminescent mesh – modern lanterns generally opt for a battery-powered light.
