This item grants +2 AC above and beyond the normal armor limit when worn. You must have 28 Levels of Blackguard to equip this item.
This item will double the duration of any Death Ward Spell cast while worn. This stacks with the Extend Spell feat.
While wearing this armor the Blackguards Call of the Grave ability becomes a gigantic pulse attack that lasts 2 rounds ...Or maybe just turns call of the Grave into one gigantic AoE when used ? (You must rest with this item on).
