one One option is farm creature products, i would sugest products. I would suggest blood crabs as ek in liberty bay.
second Second option: find a friend with a chayenne key and up character to lvl 40 to sell music box ( a friend made really good profit with it)
third Third option: minotaur task to get dwarven helmets ( not (not worth much thosedays these days but still an option)
fourth option : Fourth option farm the dry piece of wood on bewitched event depending on server they worth aloot a lot since need 500 to complete all achivments pep achievements. People pay aloot a lot for them < i would recomend them. I would recommend this option if you got aloot a lot of free time during the eventevent.
