I think I'd agree with jbear. You may have to create some Hindrances that the player can add using the Advance mechanic (since it won't charge you for taking a Hindrance, this is also how I started handling Coup in DL Noir and HoER, for instance). Equipment does only seem to provide an effect from it as long as it's in inventory so I'm not sure I can think of a way to make any effect from an item be "sticky" once the item is gone. Presumably that might require a change to the core data files, and if you would like to see that happen please be sure to post it on the "
What changes/enhancements would you like to see?" thread.
Unless maybe CapedCrusdaer or Mathias or someone with more knowledge and skill with the program besides us has some other ideas, that is.
