Sentinel (ability)

Sentinel is an ability available to Paladins in Final Fantasy XI. The ability becomes available at 30. The ability is usable once every 5 minutes and will last a total of 30 seconds after activated. During this time, the Paladin will gain +15% defense to his base score, making him significantly more resilient to damage.

Sentinel also creates an amount of enmity that is comparable to provoke, the warrior job ability. While this is true, Paladins would rarely if ever exclusively use an ability like Sentinel to generate hate, even though they are a tank. They would still rely upon their subjob, warrior, for enmity generating abilities.
