Falconry and Hawking has been important skill in a variety of places through out history. It is the sport of nobles and nomads, and many in between. In some places and times, Raptors are bonded to people, using their magic connection to everyones benefit. It is only natural that magical items connected to raptors and Hawking came into existence.
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.
