Howl, you crazy bastard! If you let forth a rousing yawp, the spirits of the Earth will answer you. Wyrm creatures far beneath the Earth's crust will cause minor tremors in the ground above them.
The extent of the damage inflicted depends on the amount of Gnosis channeled into the Galliard's 'rousing yawp'. One point of Gnosis causes a minor tremor, possibly throwing people to the ground. Three points can collapse underground tunnels, knock down trees, or open sinkholes. Five points can cause structural damage to a building, collapsing walls on anyone within several feet of it. In each case, victims should roll Dexterity+Dodge or Dexterity+Athletics to stay on their feet, escape from collapsing buildings, or dive for cover.
