This transmogrification looks good with the second tier Artifact appearance, although any weapon equipped with a frosty appearance is good. The hardest part of this outfit will be the belt as it drops from Elisande in The Nighthold. However, the other pieces of gear should be easy to get including the PvP gear which only needs Marks of Honor.

Midnight Herald's Pauldrons (Xavius - The Emerald Nighmare)
Wild Combatant's Dreadplate Chestpiece (Warlord's Season 2 PvP - 3 Marks of Honor)
Ethereal Crystal-Plated Gauntlets (Apexis Glove Trader - 20k Gold)
Waistplate of Fractured Realities (Elisande - The Nighthold)
Wild Combatant's Legplates (Warlord's Season 2 PvP - 3 Marks of Honor)
Wild Combatant's Warboots of Prowess (Warlord's Season 2 PvP - 2 Marks of Honor)
