Guild Wars 2

Hey, so I’m trying to craft some destroyer weapons and found that you need destroyer lodestones to make them. So my question is where can you find these? I’ve looked all around the web and can’t seem to find any good place to find the cores(to forge into the lodestones) or the lodestones. I’ve heard you can get them from the destroyers in Mount maelstrom, but i farmed some for like an hour with magic find stuff and couldn’t didn’t get one drop. Am i just unlucky or is there more than 1 location that the destroyers are at(there was only like 8 spawns where i was)? Any info will help, please and thank you!

lodestones drop in dungeons. You were killing in the right area for the cores btw, but it is a rare drop unfortunately.
