Horn of command

A horn of command was an enchanted musical instrument that amplified the user's voice.

Powers
The magic of a horn of command allowed the user to be heard at distances three times greater than normal. However, once per day the horn could be used to issue a suggestion to anyone within provided they spoke the same language as the wielder. The horn could also be targeted to a single individual. Doing this made it much harder for the target to resist the horn's magic.
