Although the VWG-Round silver bullet is effective through the pure silver content alone, it's potency can be augmented through various upgrades as outlined below.
VWG+C : Vampire Boost Option : So, werewolves aren't your primary nemesis? No problem! Silver all by itself is already partially effective against vampires, and the VWG-Round can be upgraded with a cast imprinted (C)rucifix for additional combined force against this pesky monster of the undead variety. What you lose in aerodynamic accuracy is more than compensated for by what you gain in take-down power!
VWG+L : Werewolf Boost Option : If you are being threatened by a (L)oupGarou, then you will definitely want this option. This subspecies of werewolf is exceedingly dangerous due to the fact that when in wolf form, they retain all human awareness and intelligence. In addition, the moon phases don't effect them, they can change at will at any time! This upgrade will be a devastating round against malicious werewolves of this type, but special precautions must be taken by the user. The standard VWG-Round is sealed in a glass ampule along with the seed from a real Aconitum plant, otherwise known as Wolfs-bane. This sealed chamber infuses the deadly poison into the already potent solid silver, guaranteeing a swift take-down. All parts of the plant, including the seed, are very dangerous even to humans, so care should be taken to never break the wax seal of this chamber. Never touch any part of the plant with your bare hands. Do not touch with your bare hand any items that have contacted the plant (like a bullet for instance...) without first washing the item down thoroughly with soap and water. For those botanists among us, the Aconitum is a lovely blooming specimen for any garden, but the seeds are fairly difficult to germinate, you must water them, and then freeze them, before they will sprout. Subsequently, in consideration for legal aspects, this boost option is being for the records officially provided to the user as a garden seed intended only for planting in a pretty garden. It just happens to be sealed in a chamber with a silver bullet.
