The Blood Harvest is one of the main pieces of content you’ll be doing during the Season of Blood, so it’s best to start your journey on the right foot with everything you need to know. Below, we’ll take a look at the basics of the Blood Harvest, what you can do during it, and what the rewards are.

Blood Harvest Basics
The Blood Harvest is open-world content that you can take part in at any time, in a rotating set of locations. Thecurrently active Blood Harvest region ismarked in blueon your map.
During the Blood Harvest, you’ll be able to hunt vampires and other enemies to obtain certain items that can be used to get rare loot andupgrade your Vampiric Powers. The Blood Harvest functionssimilarly to Helltide events, withincreased monster densitythat is perfect for leveling up.

There isno level or World Tier requirementfor playing the Blood Harvest, meaning you can jump in straight away on a fresh character,as long as your character is Seasonal.
There are several different regions the Blood Harvest can appear in, butone will always be active. Each area will be taken over by the Blood Harvest forone hour, after which it will appear somewhere else.Everything you obtain during the Blood Harvest will remain, including your Blood Lures and Seeker Keys.

You’ll gainHunter’s Acclaimby completing any activity during a Blood Harvest, including killing normal monsters. you’re able to check your current Hunter’s Acclaim amount at any of the Hunter’s Acclaim Boards around Sanctuary.
Blood Harvest Activities
There are several things you can do during each Blood Harvest, which we’ve detailed below. Typically, you’ll be doing most of these at the same time.
Sanguine Altars
Themain form of contentin the Blood Harvest is Sanguine Altars. Positioned around the Blood Harvest area, you canspend Blood Lures at these Altars to summon Blood Seekersand other enemies. Killing these enemies will reward you withPotent Blood, used toupgrade your Vampiric Powers, as well as Seeker Keys which can be used toopen Seekers Caches.
Sanguine Altars take 15 Blood Lures to open, but thiscan be done by any nearby player. If one player spends their Blood Lures, anyone nearby can kill the monsters that spawn and get loot.
Sanguine Altarscan be used again after a short time, so working with a group and sharing the Blood Lure cost is a great way to farm loot and materials.
There is also a special version of the Sanguine Altar that takes50 Blood Lures, located at theblue Blood Harvest icon on the map. Here, there are three Blood Lure Pedastals that each require 50 Blood Lures to be activated, butspawn several Elites and bosses.
Like normal Sanguine Altars, thesecan be opened by any player, meaning you’re able to work together to open them with others to offset the higher Blood Lure cost. You’ll get tons of loot and materials by defeating the bosses spawned by this altar.
Keep in mind thatyou won’t get your Blood Lures back if you give them to one of the Pedestals. Be sure youhave at least 150 Blood Luresbefore you activate any of the Blood Lure Pedestals.
Blood Seekers
Blood Seekers aremini-bosses that appear at Sanguine Altarsand randomly sometimes as you kill enemies during the Blood Harvest. As you kill normal enemies, you may see a notification pop up that saysthe Blood Seekers have taken notice of you. Keep killing enemies and eventually, the Seekers will appear.
These mini-bosses will dropBlood Lures and Potent Blood, as well asPact materialsthat you can use to change the active Pacts on your gear.
Additionally,powerful Blood Seekersmay sometimes appear at Sanguine Altars and randomly. These upgraded versions are similar toDungeon bosses, withfull-length health bars at the topof the screen. Luckily, they will drop better loot, so it’s a good idea to kill them when they appear.
Tree Of Whispers
During the Blood Harvest, special Tree of Whispers objectives will become available. These involve things like freeing prisoners from cages, destroying altars, and killing vampires. Completing these objectives will reward you with Grim Favors, which you can exchange to theTree of Whispersonce you have ten.
Random Events
Blood Harvest-themed events will also occur in the Blood Harvest area. These function similarly to other random events that occur across the world, and reward Blood Lures, Seeker Keys, Pacts, and general loot. These events are pretty infrequent, but can be useful for finding certain enemy types to kill for Tree of Whispers objectives.
