Iron Flask

Iron Flask: These special containers are typically inlaid with runes of silver and stoppered by a brass plug bearing a seal set round with sigils, glyphs, and special symbols. When the user speaks a command, he can force any creature from another plane into the container, provided the creature fails its saving throw vs. spell—after magic resistance, if any, is checked. Range is 60 feet. Only one creature at a time can be so contained. Loosing the stopper frees the captured creature.
If the individual freeing the captured creature knows the command word, the creature can be forced to serve for one turn (or to perform a minor service which takes up to one hour). If freed without command knowledge, dice for the creature's reaction. Any attempt to force the same creature into the flask a second time allows it +2 on its saving throw and makes it very angry and totally hostile. A discovered bottle might contain:
