Charnel Miasma

Access to the Death domain,

As long as you have a 2nd-level or higher Death domain spell available to cast, you exude an almost imperceptible scent of the grave wherever you go. As a standard action, you can force one foe within 30 feet to attempt a Will save or be shaken for 1 minute. If you use this ability on an already shaken creature and it fails its saving throw, it becomes panicked for 1 minute or until it spends 1 full round out of line of sight of you. Creatures that succeed on this save are not affected again by your charnel miasma for 24 hours. As a secondary benefit, you gain a +1 competence bonus to your caster level when casting death spells.

Your close connection to death magic causes others to find your company unpleasant.
