i think the hardest part is actually finding a party that will let a complete new low lv stranger leech for Cruor. And it probably wont be just once too, as you dont want to end up being a keyer with a measly 10 keys for a long party....

Ive yet to find a leechable pt lol at least on odin. They usually only shout for 2 leechers and must have tons of keys >.>
