Censer of Dark Shadows

Wondrous item, uncommon (requires attunement)

This enchanted censer paints the air with magical, smoky shadow. While you hold it, you can use an action to speak its command word to conjure a 30-foot-radius sphere of magical shadow for 1 hour. Bright light and sunlight within this area is reduced to dim light, and dim light within this area is reduced to darkness. The shadow spreads around corners, and nonmagical light can’t illuminate this shadow.

The shadow emanates from the censer and moves with it. Completely enveloping the censer within another sealed object, such as a lidded pot or a leather bag, blocks the shadow. If any of this effect’s area overlaps with an area of light created by a spell of 2nd level or lower, the spell that created the light is dispelled. Once this ability of the censer is used three times, it can’t be used again until the next dawn.
