Your strange melody of hacking gasps and pained wheezes draws upon the dark powers of Kefka to fill a witness with debilitating and distracting phlegm.
Prerequisite(s): Perform (sing) 5 ranks.
Your song emulates the sounds of a terrible illness, causing one creature you are aware of who can hear your song to develop a psychosomatic flu. If the target fails its Will save, whenever it attempts any action other than moving up to its base speed or making a single melee attack (but not both) in a single round, it must succeed at a concentration check (DC 10 + your Charisma modifier) to avoid wasting its action because of a fit of coughing and sneezing.
Use: 1 bardic performance round per round.
Action: 1 standard action.
