Hey Tyrians. Some of the rewards for the meta achievements for the newly revamped and released Living World Season 1 are actually crafting ingredients. Hover over the names of things below for links to the wiki.
The Fused Gear from Flame and Frost can be used in the Mystic Forge to create a Berserker’s Gauntlet Greathammer.
The Aetherblade Signet Ring from Sky Pirates can be used in the Mystic Forge to create the pistol Decisive Evidence.
If you already salvaged or destroyed the items, they can be purchased from Sarettokk, one of the vendors in the Hooligan’s Route (the skritt cave) in Lion’s Arch, for 10gold–not cheap, but the option is there.
