That spirt or ghost in the waterway (fourth mobhunt) was fairly hard (underleveled) until I just put everybody on a 'Nearest Enemy - Thunder' Gambit, and I put a '20%< HP - HiPotion' Gambit in the second slot, with the third as 20%< MP - Ether'. Even then I had to take out a dead chars and put Bashe into the party. (I'm glad I had all the spells owned licensed to each character... then again I buy the goodies and then liscense them out to characters.)
