Destroyer Lodestones and where to farm?
According to some “experts” in the guru forum, the best know place is:
“Destroyer Lodestone – Drops off Destroyers in Mount Maelstrom
You can also make them in the Mystic Forge if you have Cores (1 Tier below Lodestones):
2x Core + 1x Crystal + 1x Bottle of Elonian wine + 1x Pile of Crystalline Dust"
