Censer of Summoning Air Elementals

Censer of Summoning Air Elementals: This device appears to be an ornate but ordinary censer, a kind of bowl with a perforated lid and a chain which is used to lift and swing the device. These are normally used in worship, but this device is made for a different purpose. To activate this device, incense must be placed in the bowl, lit, and covered, and the command words inscribed around the edge of the lid must be spoken, which requires a full round to complete.
