Magic candle

A magic candle is a SLASH'EM specific light source. It burns indefinitely but has no possibility of granting a wish, unlike a magic lamp. It appears as a candle when unidentified.

Strategy

It is easy to pseudo-identify a magic candle. When lit, it has light radius 3 versus 2 for wax candles and tallow candles, and unlike ordinary candles, will not appear as partly used. Magic candles also cost much more than ordinary candles but cannot be sold (the shopkeeper will "seem uninterested").
