Traits are abilities not tied to a character’s species or class. Campaign traits are designed to add a hook into a campaign, and these traits are designed for Cities of Sundara: Moüd (PFRPG).
Blood of Moüd: You are descended from the original inhabitants of Moüd that fled the city after the accident when the breach between the worlds was opened. The energies from the rift bathed your ancestors, giving some of those who fled a way with the undead. You gain a +1 trait bonus on weapon attacks made against undead, or with spells or channelled energy, whether to help or harm them.
Dorunna Born: You were born amongst the Dorunna nomads that live on the rim of the Trackless Quarter and are familiar with the desert that the City of Bones can be found in. You gain a +1 trait bonus for Survival in the desert and that skill is always a class skill for you.
Scholar of Moüd: You have spent a great deal of time delving into Moüd, its history and its libraries. You gain a +1 trait bonus to all Knowledge (history) checks made in Moüd. The bonus increases to +2 if the check relates to Moüd.
