One of the
NetHack Invocation Artifacts. You get the
Candelabrum after defeating
Vlad the Impaler in the
Tower. It can hold up to seven
candles at a time.
The Candelabrum of Invocation isn't particularly useful. It's just a light source that lasts as long as the first of its candles that is lit. Note that the Candelabrum does not come equipped with candles. You'll need to acquire those from other sources, such as Itzchak's Lighting Shop in the Gnomish Town. If the Candelabrum is cursed, it will not light. Make sure it is not cursed before you attempt the Invocation.
