Integration Notes for Castles & Crusades (Siege Engine):
Siege Engine Checks: For any contraband that triggers an effect, use the standard Primes system. If a stat (e.g., CON, WIS, CHR) is a Prime for the character, the Challenge Base (CB) is 12; otherwise, it is 18, plus the Challenge Level (CL) listed in the item description.
Fencing Rules: Selling contraband usually yields only 25%–50% of base value unless sold directly to a buyer who specifically needs it.
Law Enforcement Encounter: Whenever characters carry contraband through city gates or guarded areas, roll a d6: on a 1–2, guards or inquisitors perform a detailed search.
