Blood Harvests Explained

Learn how to farm Potent Blood, Hunter Acclaim, and unique rewards during Diablo IV's Blood Harvest events. Discover locations, currencies, and strategies.

Blood Harvest events in Diablo IV are time-limited regional occurrences, similar to Helltides, that last for an hour before moving to a new area. They feature altered aesthetics, events, and enemies, offering unique rewards. These events are crucial for acquiring Blood Lures and Seeker Keys, the primary currencies used within the Blood Harvest. Blood Lures are used to activate Sanguine Altars, Blood Lure Receptacles, and Blood Wells, while Seeker Keys are needed to open Seekers Caches, which are analogous to Helltide's Tortured Gift Chests.

Blood Harvests spawn after completing or skipping the main campaign. They are marked by a green icon on the map, affect a smaller area than Helltides (typically one named region), and immediately transition to a new Harvest upon conclusion. Unlike Helltides, players retain their Blood Lures and Seeker Keys between events, making them more forgiving. The enemies encountered are usually a mix of native fauna and vampiric foes. Blood Harvests are excellent for grinding loot and experience points (XP), and are necessary for unlocking and enhancing vampiric powers. However, they do not contribute to leveling up Glyphs or acquiring endgame materials like Fiend Roses and Forgotten Souls, making Nightmare Dungeons essential for those purposes.

Additionally, Blood Harvests feature various objectives that grant Grim Favors for the Tree of Whispers. Some objectives are specific to Blood Harvests, while others are standard tasks like defeating certain enemy types. Completing these objectives and turning them in at the Tree of Whispers can magnify the rewards earned from Blood Harvests.

How to Farm Potent Blood

While Blood Harvests offer general XP and loot, their standout feature is the abundance of Potent Blood, a crucial resource for upgrading vampiric powers. The primary sources for Potent Blood are Blood Seekers (powerful elite vampires that attack periodically) and Seeker Caches. Blood Seekers can be encountered naturally, forced to spawn using Blood Lures at Sanguine Altars, or by engaging with Vampiric Syphons. Seeker Keys, required for Seeker Caches, are also frequently dropped by Blood Seekers. Blood Wells, which sometimes spawn within Blood Harvests and may require Blood Lures to access, are another source. Engaging in combat within Blood Harvests will naturally lead to the spawning of Blood Seekers, either as a direct result of the carnage or through the use of Blood Lures.

Blood Harvest Events and Hunter Acclaim

Beyond loot, XP, and Potent Blood, Blood Harvests are a source of Hunter Acclaim. This system, tied to the season's theme of hunters battling supernatural threats, is primarily earned by defeating elite vampires and completing events within Blood Harvests. These events, marked by white diamonds on the map, include activities like Corpse Piles, Injured Adventurers, Locked Cages, Monuments of Bone, and Restless Spirits. Most involve defeating enemies and interacting with an object, or vice versa. Completing these events grants Hunter Acclaim, which unlocks tiered rewards at Hunter Acclaim Boards located in cities across Sanctuary. These rewards typically include caches of loot with scaled items and Potent Blood. Notably, at Tier IV and Tier IX, players receive the Sanguine Brace and Accursed Touch vampiric powers, respectively. Reaching the maximum Tier XVIII requires a significant time investment in running Blood Harvest events.
