The subject of this article or section was part of the Scourge Invasion, a two-time world event that heralded the opening of Naxxramas in patch 1.11.0, and the opening of Northrend in patch 3.0.2.

The Blessed Undead Slaying sets can be found during the Scourge Invasion world event occurring in Patch 3.0.2. The original Scourge Invasion saw the introduction of the original Undead Slaying sets.

There are four sets, one for each armor type. The gloves and shoulders of each set are sold by the Argent Dawn in exchange for fifteen [Necrotic Runes]. The legs are Bind on Pickup and are dropped by rare spawns at the Necrotic Shards. The chest pieces are Bind on Pickup and dropped by Shadows of Doom which spawn when you disrupt the shard.

To anybody who had been doing a lot of raiding in The Burning Crusade, the sets were inferior to what could be garnered from raiding, however, to someone who had recently hit 70, the sets were easy to get and strong enough to offer some aid in the earliest levels of Wrath of the Lich King.
