This candle’s magic is activated when the candle is lit, which requires a Magic action. After burning for 4 hours, 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. While you are within that light, you have Advantage on D20 Tests. In addition, a Cleric or Druid in the light can cast level 1 spells they have prepared without expending spell slots.
Alternatively, when you light the candle for the first time, you can cast Gate with it. Doing so destroys the candle. The portal created by the spell links to a particular Outer Plane chosen by the DM or determined by rolling on the following table.
