Weapons

Evergreen stakes kill the pagan gods Madge and Edward Carrigan when driven through their hearts. The rule is specific to those beings, not a general replacement for every wooden stake.

Silver knives and bullets belong to the same material countermeasure family, but their success depends on the creature, the placement of the strike and the rule established for that hunt.

This bomb trap is an episode-specific improvised explosive. Its exact construction and effect remain tied to the governed episode evidence and should not be expanded into a general supernatural rule.

Iron tools disrupt ghosts and can hurt or block several other supernatural beings. A fireplace poker or crowbar may look improvised, but the material is doing the real work.

Dead man's blood on a crossbow bolt incapacitates a vampire long enough for capture or decapitation. The blood is the active countermeasure; the bolt is the delivery system.

Consecrated wrought-iron rounds can kill a shtriga only while it is feeding. Outside that narrow window, the same ammunition may do nothing at all.

The rawhead trap turns water and a powerful electrical current into a killing method. It works, but Dean nearly dies in the same circuit. Effective does not mean safe.

Silver bullets work when the creature is vulnerable to silver. They are not a universal monster round, which makes correct identification every bit as important as the shot itself.
