Urban Ward (Rank 1) Edit
If your home has no walls, sleeping can be a nightmare. There's no guarantee that someone won't sneak up on you to steal your stuff... or even take your life. Some werewolves solve this problem by sleeping in packs, but it never hurts to take extra precautions. Rural Garou set twigs and branches that easily snap underfoot; Bone Gnawers rig the same warnings with tin cans, tripwires, or even broken glass. With a little mystical aid, a werewolf can enlist spirits in similar defenses. The werewolf can never be sure exactly where the boundary of the urban ward is set, but he may be paranoid enough to spend more time setting multiple layers of trash around his encampment. This Gift is taught by a Rat-spirit, who usually warns its student to always collect trash and shiny things for just this purpose.
By spending one Gnosis, a Bone Gnawer can ward an area against intrusion. The "Area" can be anywhere between the size of a room and the size of a building. Trash is set around the periphery, usually junk that makes noise when it's disturbed. If anyone crosses the imaginary boundary, the Bone Gnawer hears the spirits scream a silent warning to him. The ward remains in effect for eight hours (or in some cases, from dusk 'til dawn).
The Storyteller secretly rolls the character's Wits + Enigmas (difficulty 6). Any supernatural creature attempting to use its powers to overcome the Urban Ward (for instance, the vampire Discipline: Obfuscate) must score more successes on its roll to activate the proper supernatural power than the Garou did. For more mundane creatures, like humans, crossing the boundary automatically warns the Garou, who may consciously decide whether to wake up. If the trespasser is also using Stealth, the sleeping Garou can make an opposed Perception + Alertness roll without penalty, as if he was awake. Creatures that "teleport" in by means of Gifts such as Shadow Step still count as having crossed the boundary; instantaneous passage through the Umbra is still Umbral passage through the boundary.
