Mined from thin veins of ore on the plane of Pandemonium, pandemonic silver has all the properties of alchemical silver. In addition, a thin, unearthly scream issues forth from a bladed weapon made of pandemonic silver whenever it’s unsheathed in at least a light breeze. This scream is a sonic, mind-affecting compulsion that is a fear effect. Other than the wielder, those within 30 feet who hear the scream must succeed on a Will save or cower for 1d4 rounds. The DC of the Will save depends on the strength of the wind, as indicated on the table below.
| Wind Force | Save DC |
|---|---|
| Light (0—10 mph) | 10 |
| Moderate (11—20 mph) | 13 |
| Strong (21—30 mph) | 16 |
| Severe (31—50 mph) | 19 |
| Windstorm (51—74 mph) | 22 |
| Hurricane (75—154 mph) | 25 |
| Tornado (175—300 mph) | 28 |
Pandemonic silver can be used to coat the striking surface of any slashing or piercing weapon made of steel. The cost of the weapon increases as shown below.

| One-handed slashing/piercing weapon, or one head of a slashing/piercing double weapon | +11,000 gp |
