Job Abilities
Abilities are commands that utilize the /ja command. Similar to magic, abilities suffer from Job Ability Recast that inhibits the player from repeating an ability until the delay has taken effect. Some exceptions apply since players enjoy a multitude of ways to remove the delay. However, unlike magic, abilities have no activation delay, so they activate instantly.
Using Abilities /ja "Ability Name" <target> Availability
Abilities are only available if you meet the required Job and level requirements. Generally, once a player has reached the required Job level, he or she instantly gains access to abilities learned at that level. This applies to Support Jobs as well.
Exceptions,In some cases, a player may not have access to an ability even if they meet the Job and level requirements.
