A few more examples from LotW:
Fire [Damage]
Fire damage is always aggravated. Torches and small fires touching just part of the body inflict one level of damage each turn while bonfires and flames covering half the body inflict two levels per turn and infernos and flames covering the whole body inflict three levels per turn. Garou can attempt to soak this damage, but must make a Static Physical Challenge to do so - against three Traits for candles and other sources of first degree bums, five Traits for torches and other sources of second degree bums, seven Traits for Bunsen burners and other sources of third-degree bums, nine Traits for chemical fires or 10 Traits for molten metal. Success removes one level of damage from the fire that turn.
Silver [Damage]
Silver is the metal of the moon, and Garou are uniquely vulnerable to the favored metal of the celestine who gives them so much. It’s not easy to make effective weapons out of silver, but skilled blacksmiths and gunsmiths do manage. A Garou suffers one level of aggravated damage every turn she’s in contact with silver, except for homid and lupus Garou in their respective breed forms. Garou can only soak damage from silver weapons in Homid form. Garou can carry silver, but it costs them Gnosis thanks to physical allergy and the spiritual “buzz” of the nearby threat. Lost Gnosis returns after aday away from all silver. For every five silver objects the members of a pack carry, all packmates lose a Gnosis Trait. Carrying a great many silver objects, particularly bullets, may also cost the pack Honor or Wisdom. A klaive costs the packmates a Gnosis Trait per day, and a grand klaive costs them two Gnosis each per day.
But then, in one of their oh-so-famous contradictions, WhiteWolf says:
Klaives and Other Fetish Weapons
Klaive: Level 4, Gnosis 6
This is the signature weapon of the Garou, a special style of dagger made for use in any form from Homid to Crinos. Klaives are rare and precious artifacts, not the least because each one has a pure silver blade and therefore subtracts one Gnosis Trait from its wielder’s current total. Not all klaives have spirits bound into them. A klaive without a spirit in the blade doesn’t have to be attuned, but without the spirit it only inflicts lethal damage on targets without a special vulnerability to silver. The spirit allows the blade to do aggravated damage to all targets. Pulling a klaive on a fellow werewolf generally indicates that the wielder desires a duel to the death. In successful times, klaive duels are rare; at the moment they’re rising in frequency as the tensions of the Final Day grow. Tradition-minded Garou
mourn the proliferation of klaives and their use for mundane tasks, while modern minded Garou complain about elders’ concealment of useful tools in times of need. A klaive gives three bonus traits in combat and inflicts an extra level of aggravated damage. Because it’s silver, werewolves cannot soak this damage.
Fetish Doll [Advanced Uktena Gift]: Sympathetic magic is as old as civilization, if not older, and the Uktena use it whenever they feel the end justifies this potentially abhorrent means. With this Gift, you construct a specially made doll with a piece of the victim (lock of hair, nail clippings) or something belonging to the victim (piece of clothing, jewelry), and then use the doll to inflict harm on the target from a distance. It takes one week to construct and enchant the doll once you have a piece of the victim or some important possession. Make a Mental Challenge (retest with Crafts) to complete the making. Once it’s complete, make a Static Mental Challenge against the victim’s Willpower while mutilating or damaging the doll. Success indicates the victim suffers a level of aggravated damage (soakable as per any ability the victim has to do so). Spend additional Mental Traits to inflict additional damage. The doll is destroyed and rendered useless once it transfers 10 levels of damage. If any challenge to inflict harm fails, make two Simple Tests. If both fail, the doll is immediately destroyed.
It should be pointed out that none of the abilities listed in LotW offer soaking as a benefit. This is not to say though, that the gift couldn't be used against non-garou with the ability to soak.
