Hell Yes!! The weapon main purpose would be to trap attacks that the player blocks(opposite of Nuxia) & have an unlimited chain that can feint in any direction(similar to Aramusha). Give it Undodgable heavy attack finisher properties as well.
“War Fans” was not used for warfare. They were used when Samurai was in places where weapons were forbidden. So, that would not be ideal. But, if they did a Geisha Assassin type with a Katana & a War Fan on the off hand would be pretty cool. 👍
