This metal urn is identical in appearance to an efreeti bottle, except that it does nothing but smoke. The amount of smoke is great if the stopper is pulled out, pouring from the bottle and totally obscuring vision across a 50-foot spread in 1 round. If the bottle is left unstoppered, the smoke billows out another 10 feet per round until it has covered a 100-foot radius. This area remains smoke-filled until the eversmoking bottle is stoppered.
The bottle must be resealed by a command word, after which the smoke dissipates normally. A moderate wind (11+ mph) disperses the smoke in 4 rounds; a strong wind (21+ mph) disperses the smoke in 1 round.
Prerequisites: Craft Wondrous Item, pyrotechnics.
Cost to Create: 2,500 gp (plus 400 gp for base item), 200 XP, 5 days.
