Lifeform Maker

A tabletop roleplaying supplement for creating alien creatures and base species. Quick rules allow existing creatures to be modified, while detailed tables generate new forms and define traits such as size, lifespan, colouration, communication, diet, intelligence, movement, senses, reproduction, terrain, and temperature tolerance. Additional tables provide advantages, disadvantages, and quirks, with baseline options including aquatic, avian, insect, invertebrate, mammalian, plant or fungal, reptilian, and rock-based lifeforms. Example creations demonstrate both methods.
