Sentry Candle (Patreon)

Wondrous item, common

This dark candle has a crenelated rim that remains even as the candle melts. While lit, small windows seemingly glow from within the candle's dark wax. The candle's magic is activated when the candle is lit, which requires an action. After burning for 8 hours, the candle is destroyed. You can snuff it out early for use at a later time. Moving the lit candle immediately snuffs it. Deduct the time it burned in increments of 1 minute from the candle's total burn time.

While lit, the candle sheds dim light in a 15-foot radius. Any creature within that light is mentally alerted whenever another Tiny or larger creature enters the area within 60 feet of the candle.

"I'm not refusing to keep watch, I'm sleeping on the job. And yes, there is a difference. Why do you think I sleep with a night light?"
