Ok I may be not as bright as the other high and mighty players out there. However, the people who are new to this, or the people who have little patience on leveling up the skills, may be able to learn from my methods in the simplest way.

The basic skills of all taoists are thunder and cure. If you are level 40 or below, make sure you use cure frequently. It may cost lots of potions, but bear with it till you learn meditation. Its better to be in a team so you can use cure even more and can actually be a huge boost. Use the thunder skill as much as possible too, but don't waste your time leveling up if you don't have any quests, (or don't waste your money on TG, it doesn't help much). But if you're being plvled, take that chance and try to attack as much monsters as you can. After you are level 40 and wish to be a watertao, you may continue reading. But if you are a fire tao, the rest you are reading may not be much of help (take a look at the title), but feel free to read.

If you are level 40 and above (level 44 is the best requirement to follow this method, because you can learn meditation), there is a possibility that the winged snakes [lvl 28 / 29] (at the northeast of phoenix castle map), will cause little damage on you, judging by what your equipments are. (Stay away from messengers, aides and kings though). First gather simple items like scrolls or potions, if you want. Then, go to the waterfall cave and into the portal that will take you to Wonderland.

Stay AS FAR AS POSSIBLE AWAY from the haw kings, not only they're black-named, they are like level 92! You would be smart enough to know that one hit will totally obliterate you!

Run to the top right corner of that small place to enter Dragon Pool. (Bad idea to attack the lvl 97 bandits, or is it?).

Dragon Pool is dangerous, but has certain locations where you can attack the bandits from a safe distance, (meaning that archers and taoists can take advantage of this place). Feel free to attack those bandits, they can boost your thunder skill (or fire if your thunder skill is fixed) tremendously.

If you are still looking for a higher thrill, enter Kylin Cave, which is located somewhere on south of Dragon Pool. Avoid the bandits while entering...

Finally! Kylin Cave! The best possible place for archers and taoists to level up their skills by beating up level 102 tomb bats, you can use attack skills like Thunder / Fire (or for fire taoists: fire tornado and all those other fire stuff). There are places for you to reach where those tomb bats cannot reach, but if more than one person occupies the place, it could cause problems, depending on the nature and mood of the stronger player. Some of the safe places are: the round structure filled with water near the entrance of Kylin Cave (you can jump on to its edge), or the long structure gushing with water next to the round one,(you can jump onto it's side), and the little pool next to the long structure (zoom on your character while standing near that place to reveal a little rock at the pool. Jump on it to get on). Attack the tomb bats from those safe places if you like.

(Forgive me if I didn't describe the structure/s a bit more accurately :P)
