Thief ( Final Fantasy XI ) Thief is a basic job in " Final Fantasy XI " . It is one of six jobs available to all players when they create a character . Thieves excel at " spike damage " since they get abilities like Sneak Attack and Trick Attack which can be combined with a weapon skill for massive damage while their normal attacks are noticeably quicker but weaker than other damage dealers . They have a high rating in the use of daggers and can use swords with moderate effectiveness . They also have an A + rating in evasion and A - rating in parrying on top of a passive evasion bonus to make them difficult targets to hit and make up for their light armor . Thieves , of course , gain abilities like Gilfinder , Treasure Hunter , Steal , and Mug and special abilities like Hide for stealth . Thieves are also the only job that have the job ability Flee . Becoming a Thief . Thief is one of the six basic jobs , as such , players can choose to become a thief at any time . If they choose to start the game as a thief , they will be given an onion knife in addition to the adventurer certificate and national ring ( if applicable ) . Abilities . " For a more in - depth description , see the Thief abilities page " Gameplay . Thieves are uniquely useful , their abilities range from out of combat uses to utilizing their massive speed and agility to gain the upper hand in battle . Their utility with treasure hunter is used to increase the likelihood of getting a rare drop . Support Job s . Ninja . Thieves , almost without exception , subjob Ninja from level 33 to the end of the game . Many even pick up the subjob at level 20 when they first get access to Dual Wield . Since thieves have a myriad of ranged attack options , they are often chosen as puller s for the party . Utsusemi will help negate attacks while bringing the enemy back to the party and the Dual Wield characteristic will allow them to build TP quicker . Warrior . Prior to level 20 , warrior is often used as a subjob for Thief . This is due mostly to their physical attributes aiding to dealing physical damage . Other than statistical bonuses , the advantages offered by Warrior are relatively few because by the time it starts becoming more advantageous , most Thieves will have moved on to Ninja and for generally good reason . Monk . While it is not customary of other " Final Fantasy " titles , Thieves actually have an acceptable hand to hand combat rating . Since Combo , a low level weapon skill can be combined with Sneak Attack , this is one of the highest damage subjobs to use up to level 33 . The Monk ' s high HP as a subjob will also help some of the moderate Thief defense . Ranger . Ranger is an uncommon subjob choice , but viable for a couple of different circumstances . The first of which would be for camping creatures with a wide spawn range , where the use of Wide Scan would be useful for tracking down the prey . Perhaps less commonly , some Thieves who take up a ranged capacity will want to use Ranger in order to take advantage of Rapid Shot , Barrage , and Accuracy Bonus es as well as capitalizing on the Ranger ' s ability to do ranged weapon skills . Dancer . For melee - jobs , Dancers are a very reliable subjob , due to the fact they can heal themselves only with the use of TP , which build up after every hit . Thieves , with their fast attacking daggers , and high evasion can store TP in a very fast time . The battles against the monsters will take some more time , because of using the TP to heal , instead of using it for a Weapon Skill , but it ' s a very safe way to fight . Other appearances . " Final Fantasy Trading Card Game " . The Thief appears with wind - elemental cards . " Triple Triad " . Thief has a Triple Triad card in the version playable via " Final Fantasy Portal App " .
