Haunting Voice

(Ghostwalk, page 35, DnD 3.0)

[Ghost, Haunt]

You can make your voice originate from another location.

Benefit

You can cause the sound of your voice to originate from any point you can see within 100 feet. While using this ability, all speech and other vocalizations originate from this other location. You cannot use this ability in conjunction with any magical ability that relies on sound, such as bardic music or a shout spell. Using this ability requires concentration.
