You can get all the meat you need for this in less than 30 minutes. Think smaller. Less than level 10, yellow Jungle Wurms in Metrica Province by the potato farm at [Akk Wilds Waypoint]. The hills are littered with them, run across the top, then drop down and run the bottom on the way back. each wurm, no matter how small, is giving at least 1 meat each, Was finished in less than 30 minutes, with my machine gun, (engineer), Killing 100 plains wurms, or ice wurms, etc will not give you any meat.
