The name says it all.
The Faction Crossbows mod allows Skyrim players to wield a crossbow that promotes the various factions in the game.
With the mod installed, you're able to construct a crossbow, a quiver and bolts that represent the following factions: Companions, Dawnguard, Dark Brotherhood, Thieves Guild, Imperial Legion and Stormcloaks. The Dark Brotherhood model is our favorite.
Each has some unique properties. For instance, the Dawnguard crossbow does increased damage to Vampires. A nice touch.
