 - Vigiles (Latium)
 
 ## Source

+## Stack Rules

+Unknown
+
+## Usage Patterns
+
+Place in a villa or officium near Vigiles buildings to increase the number of available patrols by +1 per Vigiles station in range. Useful for expanding fire and security coverage across densely built areas.
+
+## Common Pitfalls
+
+Misplaced radius leads to zero value; only affects Vigiles buildings within the building's range. Ensure the specialist is slotted into a building whose area of influence overlaps with your Vigiles stations.
