Fate: Venture City
The Paralyzer is a tool that Octavius provided to his ship captains years ago and have been passed down to the current captains. Each one, except for the new ones hired by Cassandra, has one of these. The item shines a concentrated blue light and whoever happens to have that light shine on them find themselves unable to move very easily. An Endurance or Physique of 4 is required to be able to move at all, but succeeding with style allows a person to move unhindered. If a victim is able to move while hindered by the light, they are able to either move or take an action that round but not both. Also while in the light the victim gains the Hindered aspect that the user gets to use once for free.
