As I have mentioned before, exact order of adding DEX is absolutely not required. It is very important to know that in order to hit creatures you depend on accuracy and level, not DEX and level. So if you have equipments that add accuracy, you can have lesser DEX.

First of all I will introduce some formulae that very few people know.

Accuracy = DEX*0.8+LUK*0.5+accuracy from skills and equipment
Avoid = DEX/4+LUK/2+avoid from skills and equipment

1 DEX = 0.8 accuracy & 0.25 avoid, 1 Luk = 0.5 accuracy & avoid

A good guideline to know that how much accuracy u need is to know beforehand what mob u are going to hunt, and check their avoid (refer to http://www.hidden-street.net).

The general formula is that if your level is 4 level below the creature, the accuracy you need is mob avoid*4-4 to achieve 100% hit rate.

Example

taurospear level = 75 & avoid = 30, so if your level is 71, u need 116 accuracy to 100% hit it.Lower level than 71 = more accuracy needed and hihger level = less accuracy needed.

General guideline for building dex/accuracy

1 DEX = 0.8 accuracy, pls up ur dex accordingly

30 – About 35 accuracy to pass the 2nd job advancement test (40-45 dex)
35 – About 60 accuracy (or about 50 dex, your mastery will boost your accuracy)
40 – About 70 accuracy (or about 60 dex)
45 - About 80 accuracy (the extra 10 accuracy should be added by scrolling)
50 - About 90 accuracy
55 - About 90 accuracy
60 – About 90 accuracy

70 – At least accuracy 100 (preferably 110-120), I know a lot will beg to differ but u will find out that at if u dun have this much accuracy, you will miss a lot of mobs that you should be hunting, like cerebus, pepe, taurospear etc

Personal advice - You should stop adding any points into DEX once your accuracy reached about 120. 120 accuracy is about the amount of accuracy that you need for the rest of your life in maple stroy mesos for all the level 70++ creatures. For this reason I suggest to those players who like to occasionally hunt higher level creatures (like balrog) to reach about 120 accuracy at about level 70 and then stop adding dex anymore. There is absolutely no need for you to pump your DEX so that your accuracy exceeds 130 in any case.
