A truncheon (in medieval times there was no formal distinction between club, cudgel, truncheon, baton etc, they hit you with sticks made out of whale-bone or wood) is a suggested tool as the title implies for causing a state of unconciousness in opponents that are hit with it, as it is light on actually causing damage.
The secret of the truncheon would come from the weapon's additional tags to render additional chances to knock foes unconcious and its [TOOL_USE: of ':SUPPRESSION]' as this item is additionally picked up by default by members of the guard with the law enforcement responsiblity, who will prefer to use this tool as rather than using their hands (since recently they were disabled from using weapons) which will hurt, be less violent and instead leave the dwarf in a unconcious state after being attacked in low escelation setting.
- A dwarf could still fall prey to someoene like a vampire feeding upon them, drown in their own vomit, other threats or simply running water nearby in a state of vunerability if someone doesn't escort them to the hospital.
As a tool, it can be imported and made in fortress out of wood or bone but not brought along by foriegn armies unless the player makes some dedicated modding changes, such as a exaggerations and transferrals of the truncheon's effects.
- Tag immune or foes currently in stances/anger/beserk cannot be subdued and have to be killed, so a squad equipped with purely truncheons as a primary weapon won't work against this individual
Loading this tool inside of a trap will make it highly likely that a strike directly or indirectly aimed toward the head (ringing against armor also) will render the person unconcious while doing a small amount of damage. It might then rely on other factors such as quickly putting them in jail as a POW or snapping their necks as to whether they have the time to recover and wake up again.
