Diablo 4: Comprehensive Keyword Glossary – Overpower, Fortify, and Lucky Hits for Maximum Gaming Success

Diablo 4 is a lot deeper than its predecessor, with a lot more ways to improve your build and your play style as a whole. Blizzard added some new words and phrases to this installment, some of which are hard to understand at first glance.

Unlocking the Mysteries of Diablo 4: Comprehensive Keyword Glossary – Demystifying Overpower, Fortify, and Lucky Hits for Maximum Gaming Success

It’s easy to change your damage and attack speed, but it can be hard for new players to figure out how Lucky Hits and Overpower damage work. This guide will help you cover all of these terms. This list of words and effects that are important in Diablo 4 is sort of a glossary. Use the above table of topics to find a word or phrase you want to learn more about.



diablo 4 armor tooltip

With armor, strikes do less damage to your character. You can get it from any type of armor for any of the five classes. The amount you get depends on the Item Power rating of the armor and any other armor bonuses you have from affixes or the Paragon Board.

Armor’s full value is used against physical attacks, and 50% of its total value is used against non-physical attacks. The other 50% is determined by the chemical resistance modifiers. Even though Armor has a flat value, it lowers damage by a certain percentage. You can find this number by moving your mouse over the text for your Armor on the character screen. The numbers listed are for PvE monsters that are the same level as your character.

Armor reduces 65% of all damage taken in PvP situations. The other 35% of damage you take that isn’t physical comes from your resistances to the elements. This is worked out after your PvP damage decrease is taken into account.



diablo 4 barrier globe

Barrier is a second health bar that can be made by using certain skills and Legendary Aspects. It is the main way the Sorcerer protects himself. Barrier sources will protect the user’s Life pool for the amount of time mentioned, taking all damage until the Barrier is broken. When you overkill the Barrier, it will take damage from your HP pool. The most your Barrier can be worth is the same as your most HP.

The Protector’s Legendary Aspect, the Sorcerer’s Ice Armor skill, and the Barbarian’s Iron Skin skill are all common ways to get Barrier.


Control Impaired

diablo4 control impaired

Control Impaired means that the target is currently being affected by Crowd Control, which makes it impossible for them to use skills, potions, or the dodge input. Crowd Control, or CC for short, is a status ailment that makes it hard for a character to move, fight, or do other things.

The only way to get out of CC affects is to use a skill that gives Unstoppable or Immune. If Elite monsters take a lot of CC affects in a short amount of time, they will become Unstoppable. Bosses can’t be Control Impaired until the blue bar under their health bar next to their stagger meter breaks. Stagger is built up by giving the boss CC effects.

When you break a boss’s stagger meter, all crowd control effects work against them at the same time. This effect lasts until their “stun” meter starts over.

Some common ways to get CC are being stunned, frozen, dazed by a monster attack, or scared.


Critical Chance and Damage

diablo 4 vulnerable health bar and critical hit

Critical hits do extra damage to the target by multiplying your skill’s normal damage by your critical strike damage factor, which is 150% by default. All hits in Diablo 4 have a 5% chance to be a critical hit, and the chances from other sources can be added together. Damage factors for critical hits can also be added together.

Affixes on items, one of your class’s core traits, Legendary Aspects, and passives in the skill tree are all common places where critical modifiers can come from.


Crackling Energy

diablo 4 crackling energy orb

The Sorcerer class is the only one that can use the Crackling Energy trait.

Crackling Energy is a ball of energy that Sorcerers can pick up to give themselves lightning, which makes their bodies release chain lightning when targets get close. By default, a Crackling Energy ball gives three charges of the Crackling Energy buff when it is picked up.

While you have this buff, every 0.5 seconds you will send chain lightning to close enemies, dealing about 10-15% of your weapon damage. By default, Crackling Energy can hit up to three enemies at once, and it can target about two-thirds of your screen. Legendary Aspects and passives in the skill tree can make Crackling Energy do more damage, let you make more chains, or give you other benefits when you grab it.

Crackling Energy often comes from lightning skill augments, the passive Static Discharge, and the Spark Enchantment.


Damage Reduction

diablo 4 damage reduction tooltip

As the name suggests, damage reduction effects lower the damage that comes in after Armor and Resistance have done their job. Damage reduction (or DR for short) sources add up, so when you put in a lot of effort, you get less back. On the stats page of your character menu, you can see where your present DR is coming from.

Affixes on items and passives in the skill tree are common places to find damage decrease. Barbarians also naturally have a 10% damage reduction against all types of harm.



Keyword Glossary: Overpower, Fortify, and Lucky Hits Explaining - Diablo 4

Dexterity is one of Diablo 4’s four core traits. It gives all classes the chance to dodge. Investing in Dexterity can also help some classes in other ways, like increasing their chance to get a critical hit or their base power. These extras are listed below:

  • Barbarian: Gives chance to hit and chance to dodge.
  • Druid: Gives the Druid a chance to hit and to dodge.
  • Necromancer: Gives the Necromancer a chance to hit and to dodge.
  • Rogue: Grants skill damage and dodge chance.
  • Sorcerer: Gives chances to hit and to dodge.


Elemental Resistance

diablo 4 shadow resistance tooltip

Resistance factors cut in half any non-physical damage that comes in. For example, if an attack does 100 Fire damage, your Fire Resistance grade would reduce that damage by 50. Your Armor grade would then protect you from the other half of that damage.

For fire, cold, lightning, poison, and shadow harm, there are resistance modifiers. Resistances work against both direct damage and damage that builds up over time.

Jewelry, armor add-ons, and gems in jewelry sockets are common places to find resistance.



diablo 4 life globe with fortify portion

Fortify is a second health pool that can be filled by certain skills and passives. It can be used by Barbarians, Druids, and Necromancers. Fortify gives you 10% less damage while it’s active and splits all damage you take equally between your Fortify and Life pools. Over time, your Fortify pool slowly goes down.

Unlike Barrier, Fortify counts as HP when figuring out how much damage Overpower does, making this a powerful way for Overpower builds to make themselves more durable and do more damage. Some class passives and items can increase the amount of Fortify that can be used at once.

Some common sources of Fortify are the skill upgrades of the Necromancer, Druid, and Barbarian. Some Legendary Aspects can also give Fortify if the right conditions are met.



diablo 4 healthy life globe

When a character’s Life pool is at least 80% or higher, they are Healthy. If your character is healthy right now, a red circle will show up around the Life globe on your HUD.



diablo 4 sorcerer class

Intelligence is one of the four core traits in Diablo 4, and it makes all classes more resistant to the effects of certain elements. Investing in this stat gives other groups extra benefits, as shown below:

  • Barbarian: Grants elemental defense.
  • Druid: Gives protection to elements and the ability to make resources.
  • Necromancer: This skill gives skill damage and protection to elements.
  • Rogue: Gives a chance to get a critical hit and protection to elements.
  • Sorcerer: Grants skill damage and elemental protection.


Lucky Hit

diablo 4 frost bolt lucky hit chance

In Diablo 4, every attack has a chance to be a “Lucky Hit.” This means that the attack has a chance to trigger Lucky Hit conditions on your skill tree’s passives, certain skills, and item affixes. Lucky Hit is shorthand for a skill’s proc coefficient, which is the chance that it will cause certain Lucky Hit benefits when used.

Unlike critical hits, your chance of a Lucky Hit depends on the skill you use. In the settings menu, you can toggle “Advanced Tooltip Information” to see what your skill’s Lucky Hit chance is. In general, skills that hit slowly tend to have high Lucky Hit values, while skills that hit quickly and more than once tend to have low Lucky Hit values. Changes to your chance of getting a lucky hit multiply with your base chance of getting a lucky hit.

When a Lucky Hit happens, each of your Lucky Hit effects will roll to see if they happen. For example, if you have three different “on Lucky Hit” affixes on your gear, when you land a single Lucky Hit, all three benefits will roll independently. Lucky Hits don’t change your damage directly, but their results usually do a lot of damage or help you in other ways.

Some skill tree passives, some item affixes, and some Paragon Board nodes can give you a Lucky Hit bonus.


Overpower Damage

diablo 4 necromancer class

Every move has a 3% chance to deal Overpower damage, which adds your current Life and Fortify values to the damage. For example, if your attack does 100 damage and you have 1,000 Life, an Overpower attack will do 1,100 damage. This extra damage is based on how much Life and Fortify you have right now, not how much they can be.

The base Overpower chance of a skill, which is 3%, can’t be changed by affixes or passives on items. Still, if certain conditions are met, certain skills and passive effects can promise Overpower damage. For example, if you use 10 Earth skills, one of the Druid’s boons gives you a sure Overpower hit.

Overpower damage factors, on the other hand, do exist and are easy to get. Some effects on items, passives in skill trees, and Ruby gems can add an Overpower increase to damage. You can also change the base damage of Overpower by making your Life and Fortify pools bigger. When your Overpower skill goes off, you’ll do more damage if you have more HP and Fortify.

The Pulverize skill of the Druid, most Blood skills of the Necromancer, and some Legendary Aspects are all common ways to get Overpower.



diablo 4 barbarian class

In Diablo 4, Strength is one of the four core traits. All classes get the same amount of Armor from Strength. As shown below, some classes get extra benefits when their Strength number goes up:

  • Barbarian: Grants skill damage and protection.
  • Druid: Grants armor.
  • Necromancer: Gives protection.
  • Rogue: Gives you more resources and protection.
  • Sorcerer: Armor is given.



diablo 4 thorns tooltip

When thorns hit an enemy, they do a set amount of damage. Except for powers that do damage over time, every time you take damage, the attacker will get thorns. This damage only goes to the attacker, but some Legendary Affixes can make Thorns hurt a small area. The damage done by thorns can also be scaled by your main class trait, such as Strength for Barbarians.

The Razorplate Unique body armor and the passive nodes on the Barbarian’s skill tree are two good places to get Thorns.



diabo 4 unstoppable icon

An Unstoppable opponent can’t be controlled by crowd control powers. This is shown by a pair of broken chains floating above the head of the target. With an Unstoppable skill, players can break out of any crowd control affect right away. If you crowd control Elite monsters a lot, they can also get Unstoppable for a few seconds. It’s also important to remember that bosses can’t be stopped until their stumble meter runs out.

Some common ways to get Unstoppable are through the Teleport skill of a Sorcerer, the Charge skill of a Barbarian, and certain Legendary Aspects.



diablo 4 vulnerable health bar alt

All types of damage do 20% more damage to vulnerable targets, which is shown by a purple aura around the target’s Life bar. If Vulnerability hits you, purple cracks will show up on your Life globe. This damage boost is added to any other damage boosts.

Most ice skills used by Sorcerers, skill upgrades for Barbarians, and some Legendary Aspects can cause Vulnerability.



diablo 4 druid class

Willpower is one of the four core traits in Diablo 4, and it increases the amount of healing you get and the damage you do with Overpower. For some classes, Willpower is also tied to extra perks, as shown below:

  • Barbarian: Generates resources, does harm with Overpower, and boosts all healing.
  • Druid: Gives skill damage, Overpower damage, and boosts all healing gained.
  • Necromancer: Allows resources to be made, increases damage from Overpower, and makes all healing better.
  • Rogue: Deals damage with Overpower and makes all recovery better.
  • Sorcerer: Helps get more resources, increases harm from Overpower, and makes all healing better.
