Sean "Dr. Kromm" Punch has been putting up a series of posts with advice for players and GMs alike for the Dungeon Fantasy Roleplaying Game on the SJG Daily Illuminator.
He put up a nice article with advice on creating monsters:
Dungeon Fantasy Tips: My Little Monster
Sean knows a lot about monsters. He co-wrote Dungeon Fantasy Monsters 1 with me, wrote Dungeon Fantasy Monster 2: Icky Goo by himself, created all of those "standard" DF creatures in Dungeon Fantasy 2: Dungeons, and provided invaluable help on Dungeon Fantasy Monsters 3: Born of Myth & Magic as well.
Plus, he did a whole article of monster mods - taking the prefix/suffix idea from DFM1 and running with it.
Useful advice if you're making monsters for DF. I do a lot of it, obviously, and Sean provides a lot of good advice in an eloquent and readable way.
