The Shard of Entsteig Plate is a legendary crafting material used by Blacksmith Haedrig Eamon to craft the Aughild's Dominion set.
The Shard of Entsteig Plate is known to drop off Feklar's Ghost in Act I: Festering Woods; and from The Archivist in Act II: Unknown Depths. Both elite Enraged Phantoms are rare spawns and might require you to create several normal difficulty games to find them. Both are also random Bounty targets in Adventure-mode.
The Shard of Entsteig Plate also drops from Lord Dunhyld (rare spawn) in Act I: Cemetery of the Forsaken - Bounty: Lady Dunhyld's bones.
Note: Ascended items (white) are required to craft these set pieces. The Ascended items drop from about every place, but my favorite farming spot is Act V: Battlefield of Eternity which contains a lot of angel armor racks. Might take a few attempts in normal difficulty for the one you need to drop.
