Hope you like the following Rappelz guide which selected from the other website by me, but it's not my work, Gamebuynow just give it a summary. Hope it can help you some.

In general, "overleveling" your armor/costume and weapon(Rappelz Rupees) are going to help you. While you do not receive the full level bonus, you do get slightly higher adds to your derived stats. On the other hand, if you are trying to save money, you may want to avoid leveling your boots, gloves, and (non-CS) helmet since each level here adds very little to your PDef.

Another option to consider is to obtain boots, gloves, and helmet every other rank and level them to 10 soon after purchase(Rappelz Gold). That allows you to spread the cost over more levels and provides much of the same protection. Note that leveling a belt increases the amount of weight you can carry, so that is something to consider when trying to decide whether or not to level it. Also note that when leveling a belt, for most, each level adds 0.5 to your PDef.

Armor: While you are still a fighter, use Warrior armor. The speed increase of hunter armor is not going to be worth it most of the time. If you happen to get R2 hunter armor, you might want to use it for running into a dungeon since that will boost your speed; however, once you are where-ever it is you are running in to, change back to warrior armor.

Tip: Before doing the job change to archer, up your rank 3 warrior armor to level 10. You can then use it as your pet's armor. You may actually want to level several rank 3 pieces of armor for this reason. Before doing this, you should check prices of warrior armor in the auction house. Sometimes people are just trying to raise money and you can purchase pre-leveled equipment there for less. This also applies to the equipment you will need to buy as you hit rank boundaries.
