Yeah actually the white one is the easier of the two, there is a purple one that will really tear you up. Can depend on what kind of treasure monster drops you get this play through I got 4 def buns early on ( while I got no lucky can cans -_- ) and was fighting one battle at a time at lev 48 Using light bomb and Charlot's flying monster skill and Kano's fire skill I managed to fight three of those purple one's , had to use all my health potions and was plain lucky but I got almost 600,000 exp. Did not say it would be easy basically you just hang out at the port so you can teleport out at the end.
But you are right generally not a good idea if you want to try it you should save right when you get there and save after every battle I have had things go sideways at lev 80 there and get destroyed before. Still it is easier imo than Eve 1s high lev island. Like I said two Gal's there you can't get anywhere else and also a treasure chest, think it gives you a nice speed skill and then the crayfish/lobster. You can get those as soon as you get the boat just run to the chest and teleport right after same with the crayfish at or around lev 40
