What Are Malignant Hearts?
Malignant Hearts are new, season-specific items introduced in Diablo 4 Season 8, fitting neatly into the ongoing theme of The Season of the Bosses. These hearts are powerful upgrade items that provide unique buffs, affecting a range of gameplay elements like skills, attributes, and resistances. They offer gameplay-changing enhancements that can fine-tune your build and bring your character to a whole new level of power.

Unlike traditional gear or skill upgrades, Malignant Hearts do not come from drops, crafting, or general gameplay mechanics. Instead, they are linked to a new progression system, wherein the players will have to go through specific steps to unlock, upgrade, and equip these powerful relics.

How to Acquire Malignant Hearts in Diablo 4
There are several ways to acquire Malignant Hearts in Diablo 4, though they are generally not obtainable through typical loot drops or crafting. Here's a breakdown of the main methods for acquiring Malignant Hearts:

1. Malignant Boss Fights
The primary source of Malignant Hearts comes from special Malignant Bosses introduced in Season 8. These bosses are scattered across the world of Sanctuary and must be defeated in specific encounters. Each boss has a chance of dropping a Malignant Heart that corresponds to the type of boss fought.

Location: Malignant Bosses are typically found in higher-level zones or special event areas and often appear in high-tier dungeons and world events.

Difficulty: The difficulty of these bosses will scale depending on your world tier, meaning they will get progressively harder to defeat as you ascend in difficulty.

Rewards: Upon defeat, Malignant Bosses have a high chance to drop a Malignant Heart, but not all bosses will drop one every time. The drop rate can be increased through certain buffs or modifiers.

2. Malignant Chest Events
In addition to bosses, special Malignant Chests can spawn across the map after completing certain objectives, such as clearing a dungeon or finishing a boss event. These chests will have the chance to contain Malignant Hearts, often as part of a greater treasure cache that includes gold, legendary items, or crafting materials.

Event Types: These chests typically appear in random locations, triggered by random events that occur during your exploration.

Malignant Affliction: You may encounter Malignant-afflicted zones, where the influence of the Malignant forces is stronger, increasing the likelihood of finding the chests.

3. Malignant Heart Purchase (Third-party)
For those who prefer to skip the grind or want to speed up their progress in Season 8, it is possible to purchase Malignant Hearts from third-party services. Websites like MMOEXP and U4GM provide access to these hearts through in-game currency purchases.

Pricing: The prices of Malignant Hearts will vary depending on the rarity, type, and amount you wish to acquire.

Availability: Keep in mind that the availability of these items on third-party sites may be subject to market fluctuations and may not always be guaranteed.

Legality and Risk: While buying Malignant Hearts through these services may seem convenient, players should always be cautious when purchasing in-game items from external sources. Always ensure the legitimacy of the site to avoid scams or the risk of account penalties.

⚠️ Tip: It's always a good idea to purchase from trusted platforms or consider grinding for the hearts yourself to avoid potential risks.
