Grace of Inarius

Grace of Inarius 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 named after Archangel Inarius, and focuses on Bone spells. In game files, this set is dubbed "Saint".

Pieces
The set consists of six pieces. All six are required to complete the set, and all six are Necromancer-restricted.
 * Inarius's Conviction (Chest)
 * Inarius's Martyrdom (Pauldrons)
 * Inarius's Perseverance (Boots)
 * Inarius's Reticence (Pants)
 * Inarius's Understanding (Helm)
 * Inarius's Will (Gloves)

Set Bonus:
 * damage is increased by 1000% (2 pieces)
 * Bone Armor grants an additional 3% damage reduction per stack (4 pieces)
 * Bone Armor, while active, also creates a swirling tornado of bone, damaging nearby enemies for 1000% damage and increasing the damage they take from the Necromancer by 10,000% (6 pieces)

The first bonus plainly boosts the damage Bone Armor deals. Coupled with the third bonus, it actually turns the spell into a damaging attack.

The second bonus increases damage reduction per stack from 3% to 6%, to a maximum of 60% at 10 stacks. However, with Wisdom of Kalan, the maximum number of stacks increases to 15, giving a potential of 90% damage reduction. An undocumented feature of the second bonus is that with every cast, all stacks of Bone Armor become refreshable, so that every new cast brings the duration of each stack to its full duration.

The third bonus creates a storm of bone shards around the Necromancer that follows them when they move. The storm lasts while at least one stack of Bone Armor remains, and has a range of 15 yards. Any enemy within it both takes damage over time and takes greatly increased damage from any of the Necromancer's attacks.

As the 6-piece bonus dictates, upon contact with the swirling tornado from Bone Armor, the damage they take from the Necromancer is increased by 10,000%, this increase for some reason does NOT have any impact on the Bone Armor itself. Meaning the Bone Armor skill which is now a swirling tornado, does not gain the attributed benefits, even though the skill itself is indeed coming from the Necromancer.

Note that Elemental Damage type of the tornado matches the Elemental Damage type of Bone Armor. Visually, the character will no longer be encased in bones.

This set is oriented at fighting in melee range. Limited Immunity rune is ill-advised with this set, as it brings the uptime of Bone Armor to just a few seconds per minute.

Trivia

 * The set resembles the armored skeleton of Saint Pancras, a Roman who converted to Christianity.
