Defensive

Hit Points: A creature's hit points determine its defensive CR before it is adjusted by its AC.

Armor Class: A creature's AC adjusts its defensive CR.

Offensive

Damage Per Round: A creature's damage per round (DPR) determines its offensive CR, which is offset by its attack bonus or save DC. DPR is determined by averaging its maximum damage output (taking the average of dice rolls, ignoring critics and accuracy) over three rounds. Areas of effect are treated as though they hit two creatures, which fail any involved saving throws.

Attack Bonus/Save DC: A creature's attack bonus or save DC adjusts its offensive CR.

Use Saves? If a creature's damage output is more dependent on save-based abilities, its save DC is used for adjusting its offensive CR instead of its attack bonus.

Size: A creature's size determines the size of its individual hit dice.

Hit Dice: Unlike player characters, the number of hit dice an NPC gets is completely arbitrary. Adjust this amount to taste.

Constitution: A creature's HP is increases by its Constitution modifier for each hit die it has.

Vulnerabilities: If a creature is vulnerable to common damage types (especially bludgeoning, piercing, and slashing damage), its effective hit points are halved.

Resistances/Immunities: A monster's HP is multiplied based on the resistances and immunities has to common damage types (non-magical bludgeoning, piercing, and slashing chief among them).

Flies and can deal damage at range (CR 0-9 only): A monster's effective AC is increased by 2 if it can fly and deal damage at range, though only if its expected challenge rating is 10 or lower.

Save Proficiencies: Increase a creature's effective AC by 2 if it has 3 or 4 saving throw proficiencies, or by 4 if it has 5 or 6.
