Horus .50 Magnum

A weapon profile for a roleplaying game, this supplement introduces a powerful magnum crafted to fire the Diabolus Round, a burst of dark energy that can kill its target or psychologically maim a wielder who lacks the ability to control it. The profile provides background lore and options for incorporating the weapon into play. It may be awarded as loot or placed in a vendor’s secret stash, with the Storyteller and players able to expand its cultural and supernatural details. The core rulebook is required.
