Diablo IV's second season, Season of Blood, will introduce almost two dozen vampiric powers for players to turn against the forces of evil when it kicks off on October 17, and they certainly sound powerful.

Bats, bones, and blood seem to be the name of the game. There are 22 powers in all, and they are not class-specific. A character can only have five powers active at a time. Much of Season of Blood will revolve around gathering Potent Blood, a new resource gained from defeating enemies that is used to unlock random powers or power upgrades from a new part of the character menu. Additional powers can be gained by playing through the seasonal quest line or by participating in a new seasonal event, Blood Harvest.

However, there is a catch. While acquiring the powers and their upgrades is fairly straightforward, players will need a new type of armor in order to actually activate these powers. Called Pact Armor, this new type of armor can roll with three different types of Pacts--Ferocity, Divinity, and Eternity. Powers will require a certain number of these Pacts be equipped in order to activate. One minor Vampiric Power, for example, may require 1 Eternity Pact, while another may require 1 Ferocity and 1 Divinity. If players happen to have a piece of gear with all three of those Pacts, they're in luck, as both of those powers will become active. Chest armor, pants, gloves, boots, and helms can all drop with Pacts, so players will need to keep an eye out for pieces of armor that will suit their Vampiric Power needs.
