Bestiary / Monster Creation

Step 3: Hit Dice

Source Pathfinder RPG Bestiary pg. 290
The next step in creating a monster is to determine the approximate number of Hit Dice it has. Hit Dice determine a wide variety of other statistics, including the creature’s feats, skills, hit points, attack bonuses, and special ability DCs.

A creature’s total number of Hit Dice depends on a number of factors, but the two most important are its CR and its type. Table 1–2 lists the average number of Hit Dice for each creature type, depending on its CR. While many of the monsters in this book are close to these values, some are not. This is because they have higher or lower average hit points to balance out their Armor Class or resistances.
