Candle of Understanding

Wondrous item, uncommon (requires attunement)

This candle appears identical to a candle of invocation, however its powers only manifest themselves in the hands of a cleric.

When lit, the candle burns indefinitely exactly as a continual flame spell. In addition, the candle has three charges. Expending a charge enables the holder to cast tongues or comprehend languages, or to gain advantage on a single Wisdom ability check or saving throw. The candle regains all expended charges each day at dawn.
