Daoh are humans that have the Heart of the Wilderness alternate racial feature from the Adv. Players guide.
This gives them two benefits. First, they add half their level to all Survival skill checks, and second, they add +5 to all Con checks made to stablize when dying and add half their level to their Constitution score to determine the negative hit points necessary to kill them outright.
This trait replaces the “Skilled” racial feature humans have.
See the Daoh page for information on the race.
