Travelers of the Cross World Inn
Van Helsing Heavy crossbow
Looks like a normal well used crossbow.
+1 vampires bane (when used against vampires it adds 1d6 damage).
When attuned by a ranger or druid it gains the magical trait to become any bow type, as well as being an oathbow. Oathbows allow you to pick one target/7 days and add 3d6 to your damage. You also have advantage on all attacks and don’t take penalties for coverage or long distance except for total concealment, against the oath target only. Until you kill the oath target or until 7 days pass you have disadvantage with any other weapon. Or attacking any other characters.
Like Abe’s axe the crossbow can turn into any bow or crossbow to aid characters in proficiency however, it will always function in terms of attacks and damage, like a Heavy Crossbow.
