Pestilence Master's Shroud

Pestilence Master's Shroud is a Class Set for s in Diablo III, obtainable at level 70. It can only drop on Torment difficulty.

All set pieces are restricted to Necromancers. Even transmogrification of these items is only available to Necromancers.

The set is Plague-themed, and is named after Deathspeaker Mykan. It focuses on corpse skills and.

Pieces
The set consists of six pieces. All six are required to complete the set, and all six are Necromancer-restricted.
 * Pestilence Battle Boots (Boots)
 * Pestilence Defense (Pauldrons)
 * Pestilence Gloves (Gloves)
 * Pestilence Incantations (Pants)
 * Pestilence Mask (Helm)
 * Pestilence Robe (Chest)

Set Bonus:
 * Each corpse consumed by any skill fires a Corpse Lance at a nearby enemy (2 pieces)
 * Each enemy hit with a, Corpse Lance or reduces the Necromancer's damage taken by 2% for 15 seconds, stacking up to a maximum of 50% (4 pieces)
 * Each corpse consumed by any skill grants an Empowered Bone Spear charge that increases the damage of the next Bone Spear by 3300%. Damage of Corpse Lance and Corpse Explosion is permanently increased by 3300% (6 pieces)

The first bonus is, in fact, the only way to fire Corpse Lance without manually aiming it. If no enemies are found, the extra Lance will not be fired. Each corpse will count as a full cast, with all runes and enhancements, automatically finding a random target in range. Note that with the Blood Lance rune, each Lance will drain Life, which may lead to uncontrolled injury with lots of corpses around. If a corpse is consumed by Corpse Lance, it will fire two of them. One can make this bonus semi-passive by using the Devouring Aura.

The second bonus is multiplicative, and results in nearly-permanent halving of all incoming damage. This does apply to the indirect casts of Corpse Lance from the first bonus.

The third bonus is applied from any corpse (not corpse-consuming cast), up to 100 charges at a time. Damage buff is static (does not change with the number of accumulated charges), and each cast consumes one charge to multiplicatively boost one Bone Spear.

Third bonus also passively and multiplicatively boosts Corpse Explosion and Corpse Lance as of patch 2.6.1. This damage bonus is not tied to Empowered Bone Spears, and instead remains active at all times.

The Johnstone, Corpsewhisper Pauldrons and Land of the Dead are very potent additions to this set.

Trivia

 * True to its name, this set is shaped like rust-ridden medieval armor, with the mask clearly being stylized to look like a plague doctor mask.
