Carrion Crown Adventure Path
Defense against Haunts
These glass vials are held within stylized cold-iron casings etched with strange runes, necromantic designs, or other eldritch markings. Within the vial roils a small wisp of white vapor, churning as if caught in a miniature vortex of air. To capture a haunt’s energies within a haunt siphon, you need only twist the metal casing to open the vial in the same round that the haunt manifests (a standard action)—this can be before or after the haunt has acted.
