In Diablo 4, Willpower is one of the four primary core stats, which enhances healing, Resource Generation, and Overpower damage. It's especially crucial for classes like Druids, Barbarians, Sorcerers, and Necromancers, who rely on these aspects. Understanding core stats is a good way to understand your build, which will help you optimize your build from the beginning.
In this guide, we will show how you can effectively increase your Willpower stat and where it works best.
Understanding the Willpower stat in Diablo 4

Depending on your build, Willpower comes in handy to sustain resource-heavy skills while increasing damage output. Specifically, if your build is made around the Overpower mechanic, it can drastically change the way you play by giving you insane damage output.
Examples of such builds would be the Earthquake Barbarian, Hammer of the Ancients (HotA) Barbarian, Cataclysm Druid, etc.
Each point in Willpower provides:
- +0.1% Healing Received (Barbarian, Druid, Rogue, Necromancer, and Sorcerer)
- +0.25% Overpower Damage (Barbarian, Druid, Rogue, Necromancer, and Sorcerer)
- +0.1% Resource Generation (Barbarians and Sorcerers)
For Druids, Willpower is one of the most important primary stats, directly influencing skill damage. Necromancers who use Blood builds also benefit significantly from increased Willpower, which directly influences Overpower damage output.
Methods to increase Willpower in your build
Equip Gear with Willpower Affixes
Find armor and accessories that specifically boost Willpower or All Stats. Many items offer bonuses to all core stats, but prioritizing those with higher Willpower values will yield better results.
Leveling up
- You get +1 to Willpower every time you level up.
Utilize Sapphires in Gear Sockets
Inserting Sapphires into your gear gem slots can enhance Willpower:
- Chipped Sapphire: +6 Willpower
- Sapphire: +12 Willpower
- Flawless Sapphire: +18 Willpower
- Royal Sapphire: +27 Willpower
Discover Altars of Lilith
Exploring and activating Altars of Lilith scattered throughout the Sanctuary grants permanent stat boosts, including Willpower. Collecting all 160 of them can give you over 60 Willpower.
Optimize Paragon Boards
As you progress, allocate Paragon points to nodes that increase Willpower. Strategic planning of your Paragon Boards can lead to a substantial increase in this stat.
Monitoring Willpower Effects
While Willpower boosts are impactful, they might not always be immediately noticeable. To assess their effects:
- Hover over the Willpower stat in your character sheet to view detailed bonuses.
- Keep in mind that significant changes to damage and critical damage often require significant increases in Willpower.
Enhancing your Willpower is essential for characters that depend on healing, resource generation, and Overpower damage. By focusing on gear affix selection, utilizing sapphires, exploring Altars of Lilith, and optimizing your Paragon Board, you can effectively boost this stat and improve your overall damage output.
