Bulletproof

A Bulletproof Vest is either an item or an intrinsic protected role that provides immunity to nightkill. The role is extremely powerful if unrestricted, since it can literally create a unkillable confirmed townie that can force a draw upon the scum and does not require any skill to use. Some common ways to make it less powerful include:

   * limit the number of uses;
   * immunity to gunshots may not provide immunity to Serial Killers, since they use non-traditional killing methods;
   * remove the immunity in a 1-1 endgame situation, since the townie lacks any way to prevent the Goon from walking up and shooting them "in the head" (the role is entirely passive);
   * give the Mafia a role which can invalidate protection, such as a Strongman;
   * do not count as town for purpose of the Mafia win;

Bulletproof townies may drop intentional Cops or Doc Tells, since it benefits them to try to draw the attack overnight. This creates a WIFOM situation for scum, if they know such a role exists.
