If you are a fan of the Diablo series, you know that stats are an essential part of the game. Stats are numerical values that represent the attributes and abilities of your character, such as strength, intelligence, vitality, and so on. Stats affect how much damage you deal, how much health you have, how fast you regenerate resources, and many other aspects of the gameplay.
In this article, we will explain what stats are in Diablo 4 and how they affect your character. We will also provide some formulas for calculating the effects of stats on various outcomes. Whether you are a beginner or a veteran player, this article will help you understand the mechanics of stats and optimize your character build.
Primary Stats
Primary stats are the main stats that determine your character’s power and performance. There are four primary stats in Diablo 4:
- Strength: Strength increases your physical damage and armor. It is the primary stat for Barbarians and Crusaders, who rely on melee attacks and heavy armor to survive.
- Intelligence: Intelligence increases your elemental damage and resistances. It is the primary stat for Sorceresses and Druids, who use magic and nature to unleash powerful spells.
- Dexterity: Dexterity increases your precision damage and dodge chance. It is the primary stat for Rogues and Monks, who excel at ranged attacks and swift movements.
- Willpower: Willpower increases your sacred damage and healing. It is the primary stat for Priests and Paladins, who use holy power to smite their enemies and heal their allies.
The formula for calculating the bonus from primary stats is:
Bonus = (Stat – 10) / 100
For example, if you have 50 Strength as a Barbarian, you get a 40% bonus to physical damage and armor.

Secondary Stats
Secondary stats are additional stats that modify specific aspects of your character. There are many secondary stats in Diablo 4, such as:
- Critical chance: The probability of landing a critical hit that deals extra damage.
- Critical damage: The amount of extra damage dealt by a critical hit.
- Attack speed: The frequency of your attacks per second.
- Cooldown reduction: The percentage of time reduced from your skill cooldowns.
- Resource regeneration: The rate at which you recover your primary resource (such as mana or fury).
- Life per hit: The amount of health you gain every time you hit an enemy.
- Life per kill: The amount of health you gain every time you kill an enemy.
- Movement speed: The speed at which you move across the map.
Secondary stats can be found on items, skills, runes, gems, enchantments, and other sources. They can also be affected by primary stats in some cases. For example, Dexterity increases your critical chance by 0.1% per point.
The formula for calculating the bonus from secondary stats is:
Bonus = Stat / Base
For example, if you have 20% critical chance as a Rogue, you get a 20 / 5 = 4 times higher chance to land a critical hit than the base value of 5%.
Tertiary Stats
Tertiary stats are special stats that have unique effects on your character. They are usually related to legendary items or set bonuses. For example:
- Chance to summon a pet: Some items may grant you a chance to summon a pet that fights by your side.
- Extra damage to a certain type of enemy: Some items may grant you extra damage to a specific enemy type, such as demons or undead.
- Extra healing from a certain source: Some items may grant you extra healing from a specific source, such as potions or skills.
Tertiary stats are not shown on your character sheet, but they can have a significant impact on your gameplay. You can find them on the item tooltips or descriptions.
The formula for calculating the bonus from tertiary stats is:
Bonus = Effect * Chance
For example, if you have an item that gives you a 10% chance to deal 100% extra damage to demons, you get an average bonus of 10 * 100 / 100 = 10% extra damage to demons.
How do stats affect your character?
Stats affect your character in different ways depending on the type of stat and the class you are playing. Here are some general formulas for how stats affect your character:
- Physical Damage = Base Damage x (1 + Strength / 100)
- Magic Damage = Base Damage x (1 + Intelligence / 100)
- Armor = Base Armor x (1 + Strength / 100)
- Resistances = Base Resistances x (1 + Intelligence / 100)
- Dodge Chance = Base Dodge Chance + Dexterity / 100
- Critical Hit Chance = Base Critical Hit Chance + Willpower / 100
- Critical Hit Damage = Base Critical Hit Damage x (1 + Critical Hit Damage / 100)
- Attack Speed = Base Attack Speed x (1 + Attack Speed / 100)
- Movement Speed = Base Movement Speed x (1 + Movement Speed / 100)
These formulas are not exact and may vary depending on other factors such as skills, items, buffs, debuffs, etc. However, they give you a general idea of how stats affect your character.
Which stats are important for each class?
Each class in Diablo 4 has a different playstyle and role in combat. Therefore, each class has different stat priorities and preferences. Here are some general guidelines for which stats are important for each class:
- Barbarian: As a melee fighter who relies on physical damage and durability, Barbarians should focus on Strength, Armor, Life per Hit, Critical Hit Damage, and Attack Speed. Strength increases their damage output and defense, while Armor and Life per Hit help them survive longer in close combat. Critical Hit Damage and Attack Speed boost their burst potential and allow them to deal more damage in a shorter time.
- Sorcerer and Necromancer: Intelligence increases your Skill Damage by 0.1% per stat point. Willpower increases your Resource Generation by 0.03% per stat point. Dexterity increases your Critical Strike Chance by 0.02% per stat point.
- Druid: As a hybrid class who can switch between human and animal forms, Druids should focus on Intelligence, Willpower, Life per Kill, Critical Hit Damage, and Attack Speed. Intelligence increases their magic damage output and defense against magic attacks, while Willpower boosts their critical hit chance and mana regeneration. Life per Kill helps them heal themselves and their pets when they kill enemies. Critical Hit Damage and Attack Speed enhance their damage potential and versatility in both forms.
- Rogue: As a nimble fighter who relies on dexterity and precision, Rogues should focus on Dexterity, Dodge Chance, Critical Hit Damage, Critical Hit Chance, and Movement Speed. Dexterity increases their attack speed and dodge chance, while Dodge Chance helps them avoid incoming attacks. Critical Hit Damage and Critical Hit Chance increase their damage output and allow them to exploit enemy weaknesses. Movement Speed improves their mobility and positioning in combat.
How to optimize your stat distribution?
There is no definitive answer to how to optimize your stat distribution in Diablo 4, as it depends on your personal preference, playstyle, skill build, item choices, and game difficulty. However, here are some general tips to help you optimize your stat distribution:
- Balance your primary and secondary stats. While primary stats are more important for your overall power and performance, secondary stats can provide significant benefits and modifiers that can make a difference in combat. Therefore, you should try to balance your primary and secondary stats according to your class and role.
- Experiment with different combinations of stats. Diablo 4 offers a lot of customization options for your character, such as skills, talents, runes, items, etc. These options can affect how stats work and interact with each other. Therefore, you should experiment with different combinations of stats and see what works best for you.
- Adjust your stats according to the situation. Diablo 4 is a dynamic game that constantly challenges you with different enemies, environments, and scenarios. Therefore, you should adjust your stats according to the situation and the enemies you are facing. For example, you may want to increase your resistances against elemental enemies, or increase your movement speed against fast enemies.
