meat farming in northpoint tower is profitable you can make enough for the boat ride in a few actual ingame days but it requires cannibalism to be effective. as well as rescuing hostages from there but you do need to keep the world difficulty under 25 to farm it effectively and also killing moot hostages for their meat instead of rescuing them is also more profitable since moot hostages give you zero reward
use and Hold down the "Rally Trumpet" skill to make them Move toward you in the most direct line they possible can.
just watch out fore the Traps on the Flore.
also have heard that if you are Spaced into Priestess, then you can heal them so they move faster, but haven't tested it myself through, a bit indecisive of what class of Weapons/Magic/Holy i want's to play whit...
