Candle of Revealing

Activate [1] (manipulate)

When lit, this black candle's eerie blue flame reveals the presence of Invisible creatures. Within a 10-foot radius of the lit candle, creatures don't benefit from the invisible condition. Their bodies are outlined, not fully visible, so they're Concealed. Once lit, the candle burns for 1 minute, after which the effect ends. If extinguished, it can't be relit.
