Achieving maximum efficiency is what power levelling is all about. The less time you waste, the more time you spend on levelling. The more experience you gain per kill, the faster you will level(12sky gold). There are various ways to accomplish these things, from simple techniques to advanced strategies. Once you become efficient, power levelling is easy.

-Time is Money, is 12sky .

Time is converted into money and 12sky by killing monsters. Obviously, the faster you kill monsters, the faster you will earn money and 12sky.

However, 12sky can be converted back into time by spending the money on pills a nd upgrades for your equipment. Spending12sky gold allows you to kill monsters faster, giving you more time to convert into more money and experience.

In this manner, spending both time and 12sky gold will result in faster experience gain. This is best in the long run as you will notice that the higher your level, the more money you will earn over time, making up for any expenses that were made.

-Inventory and Skill Bar

Managing your inventory and skill bar properly takes very little time and effort. How you do so is up to each individual, however there are many things that people do in common to save time. Devote about ? of your inventory to stacks of pills. Generally, people use the first few columns so that they can quickly replace stacks on their skill bar as they become empty. Use your trade window to store valuables and throw away anything you don’t want to keep. Selling commons and unique provides very little income and is a waste of precious time. Keep a corner reserved for your return scrolls and partial stacks so that when you are picking up items, the pills don’t clutter your inventory. On the right of your skill bar, keep 1 stack of chi pills and to the left of that, 4-6 stacks of hp pills. This is the most efficient setup and allows you to replace essential hp pills quickly. Place attack skills and the run skill on the left of your skill bar and buff skills in the middle. Duplicate this setup and vary the skills on your alternate skill bars for PvP, PvE, and buffs. Then, by simply changing you skill bar, you can access any of your skills while keeping pills constantly at the ready. All of these minor things by themselves will not directly increase the rate at which you gain experience, but they will save you time and the less time that you waste, the more time you will be spending killing monsters and the more experience you will gain in the long run.
