In Shadow Hunters, can only Hunters benefit from the Spear of Longinus?
The way I read it, "If you're a Hunter" applies to the entire rules paragraph.  Therefore, you could re-read it as:


  If you're a Hunter and your attack is successful, you may reveal your identity.  If you're a Hunter and you do, or if you are already revealed, you give 2 points of extra damage."


I could certainly see the argument, though, that two sentences are two completely separate, and so that any revealed non-Hunter could do 2 points of extra damage as well.  I believe the intent is for Hunters only, but it isn't very clear.
