Minutes pass as the Bloodhounds sniff at the edge of the bog...minutes after they've left, a short muzzle pokes out of the mud.
Ghouls live below the earth, & solely subsist off human flesh. Over the centuries, they have adapted to this lifestyle, needing far less food, water, & oxygen than a human. Close to the corpses that they feed on, Ghouls hardly seem to breathe, heart beating only a few times a minute. They feed only once every few days.
You may go five times longer than a normal human without food, water, air, or sleep.
Passive, always in effect.
