“ 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 Forest of Throck:
Throck forest is divided into three parts: a region of twisted black magic, which is dark and hemmed in with the legions of sable pine. This is Spindel, and is occupied by the hideous Ettercaps and their spider-pets. The second area is the chaotic elfin-wood, where the druids work their wyrd magic amongst the oaks. The last part is Udnalor, the home of the gnomes. Finding themselves surrounded by these chaotic forces they dwell as quietly as possible beneath the surface. Their culture is a fascinating one to visit, and in the next few miscellaneous ideas, I shall examine the ways and customs of THE GNOMES OF UDNALOR, with a view to role-playing them.”
“ The multiple-worlds theory of cosmology allows room for every religion's Heaven and Hell and other planes to coexist, with the similar planes of all the sapient beings of all the worlds in all the galaxies...How often do the wires get crossed, as it were, leaving your paladin in a Hell for hedonistic lizards, for example.”
