Ok, so you got yourself a ring of Rodcet Nife. Now what. Head to the bank. When you get there cash in your change (I ended up with a few plat after doing this quest, not to mention I also gained almost 4 lvls) and go to your guild. This is right next door for Int casters. After you train, jump in the pond near the bank and swim into the catacombs. The point that you come up at is the Cubert spawn. Run around here killing everything that is blue to you. Its generaly a fairly steady supply. You should soon reach lvl 4 if you arent already. Now that you are buy more spells, get med, and whatever else you feel you need to do. Now go back after cubes. The lvl range for these cubes seems to be 4-6 or so. Cubert himself seems to be around lvl 5. Although you might die a few times doing this, you will also succeed a few, and most likely lvl a couple of times. When you kill Cubert, sometimes he drops the dress that you need to give to Zamel? Anyhow, he is an NPC right at the top of the pond. Sometimes, he will reward you with a +3 int earing. This is not lore BTW, so you can get 2 of them for yourself.
Now you could continue to sit here and kill him for days on end as I have seen some do, but I myself feel, that people should move on as soon as they no longer get XP from something. But thats just my opinion on camping.
