Type: Monstrous
Source: Libris Mortis
Your hollow cry strikes fear into the hearts of the living.
Prerequisite: Undead type, incorporeal subtype, Daunting Presence.
Benefit: You can emit a moan as a standard action. All living creatures within a 30-foot spread must succeed on a Will save (DC 10+ 1/2 your HD + your Cha modifier) or become shaken for 1 minute. This is a supernatural, sonic, necromantic, mind-affecting, fear effect. A creature that successfully saves against the moan cannot be affected by your moan for 24 hours.
Special: If you already have the frightful moan ability (see the ghost's special attacks, Ghost Template), instead of the normal benefits of this feat, the DC to resist your frightful moan ability increases by 2.
