Look
i recomend you be a lv 7-9warroir
get a pet like twilly or the goldfish
and
go to ammytivill and get artix he is by the tree then do the quest all the way to the rite you kno the 1 about fiting the lv 12 undead

wen you start out fighting them use stun on the first turn ((if you hit then on your next turn you will get to use double attak)) you will get money and exp

then wen you get to the boss use stun with you and holy attack with artix untill you beat the boss

wen you get the weapon sell it

they sell 4 160coins i made 1k in a day doing this

good luck

p.s. you can be a mage or a rogue to you just have to be a lv 7 rogue or a lv 8 mage i just recommend a lv 7-9 warrior
