really though, anything will make you money...as long as you sell 12 of then in the AH. What I suggest is kill a couple enemies in your local area and see what they drop, then go to the AH and see what 12 sell for. Anything that is around 900-1500 per 12, just look for those enemies. Like vultures for fire crystals that sell for 2k ish and bird feathers that sell for 1400ish in Bastok. Everyone walks right by them to kill the Quadav.
