Inner Strength (Final Fantasy XI)

Inner Strength is the Monk SP2 ability in Final Fantasy XI. It doubles the player's maximum HP, heals the player by the amount that their HP increased, and increases their Counter rate to 100% for its 30 second duration.

Trivia

 * Originally, the Monk SP2 was intended to be Consummate Counter, which would have increased the Counter rate to 100% and generated a large amount of Enmity.
