Idk what everyone else is talking about when they say they dont need food, Im only 85 defense, and I get along fine with regular armor and a bunyip. Ill bring about 4 monks, but that is enough to last me for one whole bunyip. Just wear regular armor and whip them away. Each one will summon one spawn, and it wont dissapear right when you kill the nech, a little bit later, but dont kill them or anything, just leave them alone. Also, only kill them in the chaos tunnels.
