The recipes for this Cycle's World Event item are now in the Godswood!
Like last Cycle, for the peerless evolution you will need:
ALL: Dragon Armour Tail Fragment (fourth adventure)
BATTLE: Dragon Barding Caparison Fragment (first adventure)
TRADE: Dragon Armour Body Fragment (second adventure)
INTRIGUE: Dragon Armour Leather Strap (third adventure)
The items are all hand items, and are specialized to one action--7% to either Fight, Swindle, or Sabotage. In addition, in case we don't get the Legendary version of the item in the WE, start crafting some Broadswords in the Blacksmith now--they're quite long crafts and you need 5 for every Legendary crafting attempt.
