One of my long-term projects is to continue collecting and expanding my house rules into a sort of "BX DMG." A lot of these were compiled into RS1 Fang, Faith, and Legerdemain (like the manufacture of holy water, arming and disarming traps, and alchemy rules), But there are a lot of cool things I have planned for this future edition (like information for creating campaign-specific pantheons to support thing like this worksheet).
Today's information comes via my home campaign, where they players were a good distance from civilization and found themselves facing a den of werewolves. They realized that they were significantly short on silver ammo and tried to improvise. With a bit of hindsight, it turns out that what I allowed them to accomplish in the field was far from reasonable, even in the context of a game.
So, to that point, below are my revised house rules for silvered weapons.
SILVERED WEAPONS
In many campaigns, there are creatures may only be harmed by silvered weapons. Although it is ultimately up to the DM to determine which creatures are affected by silvered weapons, these typically include: lycanthropes and other shapechangers, certain demons & devils, a number of undead, and a selection of fey and spirits.
A silvered weapon is one whose striking surfaces have been plated, bonded, or inlaid with sufficient silver to count as “silver” for purposes of overcoming specific creature defenses.
Silvering a weapon does not make it magical. It merely allows the weapon to strike creatures vulnerable to silver.
PROFESSIONAL SILVERING
Silvering Normal (Mundane) Weapons
Any normal, non-magical weapon may be silvered, assuming there is access to a properly equipped forge and a qualified smith (a master weaponsmith, silversmith, or white-smith). In small settlements, such equipment and/or expertise may not be available.
Standard professional silvering methods include:
- silver plating or bonding onto the striking edge
- silver inlay along cutting surfaces
- partial surface alloying
- reinforced edge wrapping
The base cost in silver pieces equals 100 sp (10 gp) × the weapon’s maximum damage. For example, a weapon that deals 1d4 damage (maximum 4) costs 400 sp (40 gp) to silver, while a weapon that deals 1d8 damage (maximum 8) costs 800 sp (80 gp). This cost includes both material and skilled labor. The silver used represents enough precious metal to properly plate or bond the striking surfaces.
The time required to silver a weapon equals one day per 2 points of maximum damage (rounded up). Work cannot be rushed without risk of failure. Particularly large or complex weapons may require additional time (at the DM’s discretion).
Pre-Silvered Weapons
In larger towns and cities, merchants may occasionally offer weapons that have already been silvered. These are typically produced in small batches for resale rather than commissioned individually.
Pre-silvered weapons are sold at approximately 75% of the normal custom silvering cost. This reduced price reflects simpler workmanship, thinner bonding, or less refined finishing compared to bespoke work ordered from a master smith.
In regions plagued by creatures vulnerable to silver, demand for silvered weapons increases sharply. Prices for both stock and bespoke silvered arms may rise accordingly — sometimes well above the standard rates (2–3× or more) — or, in heavily fortified settlements, modestly decrease if production is common and competition among smiths is strong. Availability should reflect local fear, trade routes, and access to silver.
While fully functional against creatures vulnerable to silver, such weapons may be somewhat less durable than custom-silvered arms at the DM’s discretion (see Limitations of Silvered Weapons, below). Availability is never guaranteed and should depend upon settlement size, trade activity, and local demand.
Silvering Magical Weapons
As a rule, magical weapons resist alteration. The enchantment binds the material in a fixed mystical state. Attempts to silver a magical weapon generally fail unless special research, ritual, or rare alchemical silver is employed.
The DM may allow such work in exceptional cases, but the work should require significant cost (5,000–10,000 gp or more), substantial downtime (1–2 months at a minimum), and a high risk of permanently damaging or diminishing the weapon’s enchantment (50% or greater).
IMPROVISED SILVERING BY PLAYER CHARACTERS
Characters without access to a silvering resource may attempt to silver weapons themselves. Such efforts are not likely to succeed without the proper equipment and expertise.
To work with silver, it must be brought to full melting temperature. A campfire alone is insufficient unless carefully enclosed and fed with sustained airflow. At a minimum, a small clay furnace, charcoal fuel, and improvised bellows (or steady forced air) would be required for silver to reach workable heat; this might make melting silver to a workable state in the field possible, but far from guaranteed.
At most, and only with the required heat and equipment, the DM may permit the casting of rudimentary silver slings bullets and the forming of silver arrowheads in the field. Additionally, unless the character (or characters) working the silver have any significant expertise, the resulting silver ammunition is incur minor to major penalties to both “to hit” and damage rolls (–1 to –3) due to flaws in the workmanship.
LIMITATIONS OF SILVERED WEAPONS
Silvered weapons require occasional maintenance to remain effective.
Silver is softer than steel. Even when properly bonded, a silvered weapon is less durable than an untreated steel weapon. Whenever a silvered weapon rolls a natural 1, it takes a significant amount of damage. After 3 such instances, the weapon no longer counts as silvered. It must then be re-silvered to restore its status as silvered.
Even in the absence of such critical fails, any silvered weapon that has seen significant use during a full adventure is considered to have incurred the same amount of damage as a single failed “to hit” roll with that weapon.
Silver ammunition has lower recovery rate than standard ammunition. Assuming the standard recovery rate for ammunition (non-magical sling bullets and arrows) is 50%, the recovery rate for silver ammunition in good enough condition to be used again is 25%. If not recoverable for re-use, there is 50% chance of recovering the raw silver from the lost ammunition (usually 1–2 sp for a silver arrowhead and 4–5 sp for a silver sling bullet).
