There are 5 types of creatures in the Elemental Worlds: beasts, humans, monsters, mutants, and spirits. Beasts and humans, being the most abundant, will most likely be the creatures you face most often, especially at lower levels. Monsters and mutants may come later on down the road, depending on the campaign. They are beasts and humans that have been touched by spirits, turning them into creatures with abilities beyond their original forms. Spirits are the creatures with the highest potential challenge rating in Elemental Worlds, being otherworldly, ethereal beings, whose existence predates the material world, their potential powers far exceed any human’s and some are simply immortal. Naturally, creatures of any type are not inherently enemies. They have alignments and wills of their own, and a creature that might be a friend to some could be an enemy to others.
