Where the rule of law is seen as being absent, weak, or too oppressive to want, and crime of all kinds flourishes, sooner or later people will take the law into their own hands and become vigilantes. Here are seven such gangs.
I had me a dream once. Just after I *acquired* this here knife. Only the knife was a bit shinier and I was in an alley somewhere. I dunno, maybe it was Brie or Holsten, someplace like that. Anyways, I'm walking down this alley when I comes across some dumb bloke trying to shortcut his way to market. Like *my* alley is a god-d**ned thoroughfare for just anyone!
Rather than making a baddy impossible to hit, consider giving it mega-hit points.
Super hard to hit leads to great player frustration. Allowing them to do damage leads to a sense of accomplishment. another variation of this would be to give the bad guy a forcefield that shows damage.You could also give them a mastermind ability that sluffs the damage of to minions who should be easy to kill.Once in a while a super high to hit encounter is ok ,but it should be few and far between.
