Styx Collar
The Gates of Hell (Dice Freaks)
Grimoire of Cosmic Entities Volume One By Eli Atkinson, William Church and Serge W. Desir, Jr.
Original Concept by Serge W. Desir, Jr.Full netbook can be found on the following website
This magical collar wrought of adamantine and soulsteel keeps the pernicious effects of the Styx at bay. The collar also provides immunity to any water-based attacks (note: natural effects such as rough water, or drowning, do not count as attacks), including Holy Water; however, contact with Holy Water neutralizes the collar for six hours, leaving the wearer open to future water-based attacks (and fully susceptible to the effects of the Styx).
