A monster has a stat block that contains the rules necessary to use it in the game. Stat blocks are divided into the following parts, which correspond with the example stat block, Vampire Familiar:
1. Name and General Details. The name of the monster is followed by its size, creature type (along with any descriptive tags), and alignment.
2. Combat Highlights. Armor Class, Hit Points, Speed, and Initiative are provided here.
3. Ability Scores. A monster’s ability scores, ability modifiers, and saving throws are listed here.
4. Other Details. The monster’s Senses, Languages, and CR entries appear here. Additional details appear in some monsters, such as skill proficiencies, Resistances, Immunities, and Gear. If a monster lacks those details, entries for them don’t appear.
5. Traits. Monster characteristics that are active at all times or during certain situations appear here.
6. Actions. The monster can take the actions here in addition to those in the Player’s Handbook.
7. Bonus Actions. This section provides a monster’s Bonus Actions, if any.
8. Reactions and Legendary Actions. These sections provide Reactions and Legendary Actions, if any. The example monster doesn’t include these parts.
