Last Resort
From Final Fantasy Wiki
Last Resort is an ability for Dark Knights in Final Fantasy XI. It becomes available at level 15 and is usable once every 5 minutes. Last Resort is very similar in its affect to Berserk, the Warrior ability. The ability will increase a Dark Knight’s Attack characteristic by 15% while it will drop his Defense characteristic by 15% as well.
Also, unlike Berserk, it creates a very considerable amount of enmity, so it is likely to draw the attention of any creatures the party might be fighting, so it is quite likely that the Dark Knight will take a lot of additional damage after using this ability. Unlike Berserk, this status only lasts for 30 seconds. Generally, this means that Last Resort is only used by Dark Knights just before using a Weapon skill.
