From Salem Wiki
When any one of a character's Humours is drained to zero, the character becomes Knocked Out. Upon being knocked out, the following things happen:
- Any items stored in your inventory or backpack are dropped. The items can then be picked up by anyone. Equipped items are safe, as are items in Pockets and Toolbelt. However, they can be looted from you by a character that has learned Larceny.
- You will lose 2 skill levels at random.
- While you are knocked out, it is possible for another player to give you a Beat Down, which will cause a Fracture and must be cured with a Crude Splint.
- While you are knocked out, you may easily be murdered or looted.
