Destiny’s upcoming expansion, The Dark Below, has already produced quite a lot of leaks of what could/ will be included in it. New legendary gear items have been discovered and they point to a full raid set. As you already know, Destiny has what’s called ‘raid gear’, a gear set that only drops during raids. The Vault of Glass has a complete set for each class, and so will Crota’s End. You can find the full set for each of the three classes below. Titan Helmet – Willbreaker’s Watch Chest – Willbreaker’s Resolve Gauntlets – Willbreaker’s Fists Leg – Willbreaker’s Greaves Mark – Mark of the Pit Warlock Helmet – Deathsinger’s Gaze Chest – Deathsinger’s Mantle Gauntlets – Deathsinger’s Grip Leg – Deathsinger’s Herald Mark – Bone Circlet Hunter Helmet – Unyielding Casque Chest – Relentless Harness Gauntlets – Dogged Gage Leg – Tireless Striders Mark – Shroud of Flies Some of those pieces have abilities linked to The Vault of Glass raid. So either they’re just placeholders, or these sets may not be raid gear for Crota’s End after all.
