Creatures with increased Hit Dice are usually superior specimens of their race, bigger and more powerful than their run-of-the-mill fellows.īoth intelligent and nonintelligent creatures with an unusual heritage or an inflicted change in their essential nature may be modified with a template. Intelligent creatures that are not humanoid in shape, and nonintelligent monsters, can advance by increasing their Hit Dice. When a monster adds a class level, that level usually represents an increase in experience and learned skills and capabilities. Creatures that fall into this category have an entry of 'By character class' in their Advancement line. Intelligent creatures that are reasonably humanoid in shape most commonly advance by adding class levels. These methods are not mutually exclusive-it’s possible for a monster with a template to be improved by both increasing its Hit Dice and adding character class levels. However, there are several methods by which extraordinary or unique monsters can be created using a typical creature as the foundation: by adding character classes, increasing a monster’s Hit Dice, or by adding a template to a monster. Each of the monster entries describes a typical creature of its kind.
