Stronger actions require more points than weaker actions, and if a character equips a crown with certain proficiencies, they may require less Action Points to perform a command than other jobs; i.e. a Black Mage can cast Black Magic for fewer Action Points than the other jobs. The Sage also learns abilities that lower the AP cost for Black and White Magic. Action Points can be restored during or outside of battle with Ethers and Hi-Ethers. Sleeping at an inn fully restores Action Points.
