I'm not the foremost expert on Thief, but I though I would write my own Thief guide. This is just my opinion and in no way should you think you have to do things the way I do...this is just a guide and things that I considered to be helpful. I have not yet reached lvl 75, but as I level I will update this guide. I hope this helps.
Thief - It can be a fun yet challenging job to master. At times invites are slow. So you will learn to setup your own exp parties. Thief is unique because they are the only job you can set hate on another player, so be careful, because you can also easily kill other people too.
For those of you who have just started playing the game I would suggest first: leveling Thief to level 18, then do the subjob quest Elder Memories in Selbina. Second: Level Warrior to 30 or 37. Third: Do the Ninja Flag Quest and unlock Ninja(your main subjob) and level it to level 37 and obtain Utsusemi: Ichi and Ni. You can also do the Ranger Flag Quest and unlock Ranger, Wide Scan comes in handy when camping NMs.
Mithra - This would be the best starting race for THF due to their high DEX.
Hume - You fall in second place...you have good all around base stats, but gear can fix what you lack.
Other Races - Don't let your lack of stats think you have to limit your job leveling range...you can always get gear to improve on what you lack.
Dexterity - This is the stat that powers Sneak Attack. For every two points of DEX a character has, his/her accuracy is raised by one point. ach point of DEX adds 1 to your weapon damage for the Sneak attack hit. It is said that each point of Dexterity raises critical hit rate by 0.1%.
Agility - On of the biggest things AGI does for Thief is it powers Trick Attack. It also increases evasion, parry, and ranged accuracy. For every two points of Agility a character has, these stats are raised by one point.
Strength - Don't worry to much about STR, where as most of our weapon skills use mostly DEX mods. Every two points of Strength raises your characters Attack and Ranged Attack by 1 point.
These levels go kind of slow. Daggers do not have a great damage output so use a sword, but keep dagger capped always (dagger is our weapon).
Just kill the mobs outside of your home nation. I would also suggest working on marksmanship. I would by a crossbow and try and keep marksmanship capped, because sadly, most of the time you are the resident puller in EXP parties. As far as gear goes anything will work.
I would suggest partying in Valkrum Dunes or Korroloka Tunnel. Up until level 15 your damage output is anything but great. But alas, Sneak Attack, you can now do a fair amount of damage especially when you stack it with a non-elemental weapon skill, such as Fast Blade. Keep in mind it will not stack with Burning Blade or elemental dagger weapon skills like Gust Slash. Don�t get yourself killed! You will find that you will steal hate from the tank often, the best thing I can suggest is don�t do this at the beginning of the fight. Wait until the end to SA; give the tank some time to build hate before you decide to steal it and die. If you are not careful during the pre-trick attack stage you might die a lot.
You now have a subjob, I would suggest to sub Warrior until level 20, seeing as how that�s when it is some what useful because of dual wield. You could sub Warrior up until level 24 until you get Utsusemi. You now also have Treasure Hunter, its time to start farming!
You will most likely be XP�ing in Qufim Island. I hate this place, it is very dangerous at night because of all of the undead. At level 24 for you will now have Utsusemi: Ichi, so at this point you might want to switch your subjob over to Ninja if you haven�t already. Shadows come in handy when you have those long pulls. Remember to keep your Dagger skill capped as you will still be using a sword.
At about 24-30 you will start partying in Yuhtunga Jungle and then at about level 28ish go to Yhoator Jungle. You have now moved on to Kazham and at level 30 your struggle is over. You have just learned Trick Attack. You will find that if you don�t know what you are doing you will kill other party members, I can promise you they will not be happy. You need to understand your job and know you role in the Party.
Odds are is that others in our party won�t understand your job either. Setting up SATA can be rather tedious at times, especially if the tank and other melee jobs are inexperienced. Be patient, and be sure to explain before you start killing.
When the mob comes, have the non-tank provoke first (this will be your trick partner), then you can SATA + WS on the tank setting massive hate on the tank. People might not understand the concept, but this is the way it works. Remember to keep your Dagger skill capped, you will soon find out why.
|THF---> TANK---> MOB---> <---DD or THF--->DD--->MOB---><---TANK|
There are few different places you will be partying at. 30-35 You will be in Garlaige Citadel or Eastern Altepa Desert. 35-43 go to the Crawlers' Nest. Kill Worker Crawlers until 38 then swith to Soldier Crawler/Hornfly until level 43. Levels 43-51 Quicksand Caves and kill Beetles and Anticans. 52-55 Kuftal Tunnel and kill Robber Crabs. Then I hope you kept your Dagger skill capped�if not do it now. If you did you have learned Viper Bite the pi�ce de r�sistance of Thief up until Dancing Edge. Viper Bite alone is useless, but when you combine it with SATA�you can do massive amounts of damage�when closing the skill chain (SC) you will also notices it causes massive amounts of damage. During these levels I found that the most common SC you will be closing is distortion. So be sure to setup a SC before you start killing to kill�em faster.
At this point you potential of killing other party members is great�so you need to be careful. Learn from mistakes you make�I�m sure you will make a few like I did. Play it safe, be sure to set most of the damage you do on the tank (your main goal for SATA) before you SATA on your trick partner.
Here comes the easy part at 54-58 go to Wajaom Woodlands and kill Lesser Colibri then at 58-60 zone to Bhaflau Thickets and kill Lesser Colibri/Aht Urhgan Attercorp. You have now learned Triple Attack, ASSASSIN, and Dancing Edge! Up until this point there wasn�t a real need for Accuracy Gear, but with our new toy, Dancing Edge, that is about to change. Dancing Edge misses a lot. Do your best to max out on accuracy.
