“ 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.
Your mileage may vary”
“ The Orcish Mustang - a semi-wild horse tamed and domesticated by orcs to serve as their mounts. Large, strong bodied, and fearless as they live among orcs. On the other hand, bad tempered, with teeth problems, sometimes have hoof problems, and agressive. In lean times, or when an animal dies, the orcs suddenly have a dearth of meat, and hide to work with.”
