Every GM must have a favourite monster. I have played under GMs that loved Orcs and another that loved dragons. In the later’s case in any ‘benefit of the doubt’ call chances are the GM would side with the dragon. With dragons I think that is fine, they are meant to be the top of every food chain and you should take fighting one very seriously and relying on Luck is not a good plan.
One of my favourites is the humble Kobold. I kind of like the concept of ‘monster’ and underdog both concepts are definitely present with these little chaps. Life is cheap when your No. Appearing is 3-300. (Actually it is 5-20, 3-300 is for their slightly tough Urd cousins who have 2-5 hitpoints.)
At the other end of the scale I quite like Pit Fiends. they add a certain je ne c’est quoi to a battle field as only a Lawful Evil Genius can. With one of those at the back it gives otherwise easy cannonfodder a bit of backbone and an excuse to out smart the players, they are geniuses afterall.
I don’t think I show bias towards my personal favourites afterall is it not as if you need to keep them in tip top shiney condition as I have as many of them as I want, as often as I want. It is not the same as having a favourite PC in which case every one is an endangered species and the last of its kind. If a horde of kobolds kill the party it does not enhance the game or add to the fun. Having an uber tough fighter crying for help and parrying for his life and then being rescued by the party healer; now that is fun and everyone lives to tell the tale and fight another day. If the fighter is less arogant and the healer feels a bit more involved in the game then that is cool i my opinion.
But what about you? Do you have favourite monsters? If so why?
