There are three NPCs that can be lured/knocked out with this blackjack: villagers, bandits and Menaphite Thugs, all located in Pollnivneach. However for luring/knocking out these NPCs, the player must have the right Thieving level: level 30, 45, and 65, respectively. When fighting with a blackjack, there is a slight chance that it will stun the opponent.
