At the bottom of this page will be a list of all of the Final Fantasy XIjob abilities in alphabetical order. Listed immediately below this though there is a list of all of the abilities broken down by job. It also displays the level at which the job first can benefit from the ability. Players using a certain job as a Support Job gain that ability, unless it is labeled as a two-hour, at twice the level listed (ex: Warriors gain provoke at level 5. All other jobs using it at a support job could gain this ability at level 10).
Listed below are only normal abilities available through leveling up from 1-75, the maximum level for Final Fantasy XI. There are additional spells and abilities available to each job which can be unlocked through other means.
The level cap for the game was raised throughout the Abyssea expansions and is now 99, and each job has been given new abilities and spells since the end of the 75 cap. In addition to this, the old two-hour abilities now only have a 1 hour recast time, and all jobs learn a second "two" hour at level 96 (though the recast time has been reduced, many players still call these abilities two hours.).
