Candle of Revealing

This sacred candle wards an area from evil, while constituting an opening between the visible and the invisible. This candle's magic is activated when the candle is lit, which requires a Magic Action. After burning for 1 hour, the candle is destroyed. You can snuff it out early for use at a later time. Deduct the time it burned in increments of 1 minute from its total burn time. While lit, the candle sheds Dim Light in a 30-foot radius. Creatures and objects that have the Invisible condition and are within that light, are revealed as if they were visible. In addition, Fey, Fiend and Undead creatures can't willingly move through the light produced by this candle by nonmagical means unless they first succeed on a DC 14 Charisma saving throw. If the creature tries to use teleportation or interplanar travel to do so, it must first succeed on a Charisma saving throw against the same DC. On a success, the creature becomes immune to the effects of this candle for the next 24 hours.
