The Captured Firefly is one of the rarest out of combat pets players can get in the game. It has a ridiculously low chance to drop off Bogflare Needlers in Zangarmarsh. What makes it even more aggrivating is that the Bogflare Needlers only spawn in one area of Zangarmarsh. There are roughly 10 - 15 Needlers in the area and their spawn time seems to vary between 2 to 5 minutes from the time they are killed.
Captured Firefly Farming Location
Above is a map of the only locations they can spawn in Zangarmarsh. If you get here and there happens to be some competition, you mine as well leave and come back another day. If you stay and try to compete you'll just waste everyones time. If you get this pet and keep it chances are everyone will be like "OMG WTF WHERE YOU GET THAT?!?!?!?!?!" when you take it out. However, you may also be able to sell it for 2-3k gold. Just keep saying in /2 WTS [Captured Firefly] very rare vanity pet 3k gold ...
Some people of course will tell you that you're crazy, retarded or just downright dumb. However that's their fault that they're too lazy to look up the drop rate. They also didn't go through the pain of farming it like you did =D.
Average Time It Takes To Find It: 2 days of hardcore farming
Average Amount of Kills: Reported to be 1k +
Average Amount of Gold Made While Farming: 500-750g
