Go to any populated world, with a bone broach, then stand close to the fights and morph. Most people will see you as a pile of bones and think nothing of it.
When any drops appear, pick and run. On opening day i looted 3 invys of rocktails, 2 invys sharks, a terrorbird of brews, and a few super potions.
This made me about 300k in an hour. Not the best method, but still good.
