This mod only replaces the slave collar with a heavy shock collar. I'm not experienced in modding, so if something goes wrong, it's at your own risk. For me the mod works fine. Requirements: Devious Devices 2.0 To make the collar gives really shocks, you need to download Deviously Cursed Wasteland 1.4 There is a quest with a shock collar.  Slave Collar: - dcw_slavecollardropchance: % chance that your slave collar will lock when the container is opened.
