From Team Fortress Wiki
This weapon deals 90% less damage than the default Bat, making it an inefficient means of killing enemies. However, hitting an opponent with the Fan O'War "marks them for death", denoted by a white skull and crossbones icon appearing over the target's head. Upon being marked, the target hears a distinctive sound, and a skull icon appears on their HUD. During this period of 15 seconds, any subsequent hits taken by the target will be mini-crits. Only one player at a time may be marked by this weapon. If another player is hit with this weapon whilst another is marked, only the most recent one will be marked for death.

- The Fan O'War's description is written in Haiku format and is a parody of a haiku written by seventeenth century poet Matsuo Bashō. However, because this reference plays off of an English translation of his work, it does not follow the traditional 5-7-5 syllable pattern of haikus, instead following a 5-5-5 pattern.
