“ 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”
“ Hungry Tumbleweeds
It is almost impossible to believe. Simply mind bending. These carnivores are actually the strangest undead you can meet! With ac as plate and 2HD, these animated plants are found in desert and grass lands. They are effected by anything that harms undead, hiding among ordinary tumbleweeds. Whats next Killer Tomatoes!?!?
Ever wonder where minor evil souls go that are unclaimed. Wonder no more. Minor evil souls wander unclaimed throughout the worlds.ordinary tumbleweeds attract them for unknown reasons. These souls also tend to group and somehow find the weeds. When the weeds are disposed of there is a 50% chance that the souls will survive and go into another weed.”
“ A group of humans living in a mountainous area have spent generations mining, drinking home made liquor, and generally not spreading the gene pool around enough. The end result is a sub-race of humans who no longer have necks, rather their heads protrude from the upper portion of the torso between the shoulders. They have beards, and lacking the ability to turn their heads, can only see what they are directly facing. They are simple and to the point, and direct to the point of bluntness.”
