Blizzard has announced a bizarre contest, where players can win a Diablo 4-themed PC infused with real human blood. It’s only for US citizens. All they have to do is donate blood at a clinic of their choice and submit proof of their donation, which will then be added to a running total.

The giveaway will begin when 666 quarts (1332 pints) of blood have been donated. The grand prize is a unique “custom liquid-cooled PC infused with real human blood”, according to Blizzard. The PC will feature NVIDIA GeForce RTX 4090, an Intel Core i9-13900K, 64 GB of DDR5 RAM and 3 TB Gen5 NVMe M.2 SSD storage, and will come in a custom Diablo red/black colour palette with Season of Blood graphics.

Although the PC can only be won by US citizens, the campaign will also unlock in-game items, which will likely be available to all players worldwide.

Once tier one (33%, or 439.56 pints of blood) has been reached, players will get a Bloodpetal Anlace dagger, a Bloodpetal Sever axe, a Bloodpetal Blade sword, a Bloodpetal Bludgeon druid staff and a Bloodpetal Heart necromancer offhand weapon. When tier two (66%, or 879.12 pints of blood) has been reached, it unlockes the Loch Raeth Maor armour for the Barbarian class. Finally, if tier three (100% or 1332 pints of blood) is reached, it unlocks the Vermillion Eye Piebald mount.
