Well, you should generally farm with a bow, because with a bow you practically don't have to move inside the bandit den.
But if you really want to, you can farm with a blade too.
Level bicheon and fire to 7.
From bicheon, take smashing level 2 and illusion chain lv 1.
From fire, level the imbue to lv2.
You will end up at 16 with a 9 level gap. If you want to farm alot, you will need to delevel once you hit level 17.
Lv 16 is the ideal moment to farm, because you get a new degree of weapon. When you level to 17, commit suicide like 50 times, until you get back to the start of lv 16. Alternatively, look for a person who has res skills, so you don't waste time returning from town.
