If the DMW reel spins to 2-2-2 outside of modulation phase, Zack is granted with No MP Cost for the rest of the battle's duration. 7-7-# grants No MP Cost for 15 seconds, and #-7-# grants No MP Cost for 12 seconds. The accessory Soul of Thamasa grants the status when equipped. Soul of Thamasa can be found during missions 9-4-4 and 9-6-5.
If the DMW reel spins to 4-4-4 outside of modulation phase, Zack is granted with No AP Cost for the rest of the battle. 7-#-# grants No AP Cost for 12 seconds. The accessory Laurel Crown grants the status when equipped. Laurel Crown can be acquired by clearing mission 9-5-4 or by finding it during mission 9-6-2.
The Genji Helm grants both No MP and No AP Cost.
Spellspring is gained from the Twin Stars (one ally) and Three Stars (all) item. The status eliminates the use of MP and allows the target to freely use their spells and skills. The status can also be acquired through Rikku's Mix by mixing either Freedom (no MP cost for one target) or Freedom X (no MP cost for all targets). Also in a related manner, Lulu's Overdrive can freely cast any Black Magic for no MP cost.
Spellspring is again gained from the Twin Stars and Three Stars items. The accessory Ragnarok grants Spellspring, and can be obtained by blaming Rikku for the Mi'ihen Highroad mystery in chapters 3 or 4. Spellspring can also be cast by MP Mambo, a dance for the Songstress.
MP Mambo requires the Key Item Magical Dances, Vol I, which is given to the player after they defeat all the bosses in the Den of Woe in Chapter 5. The effect is also gained with the Lady Luck dressphere with the mastered ability SOS Spellspring whenever the character falls in HP Critical health.
Manafont is the Black Mage's Special Job Ability in Final Fantasy XI. The ability will invoke a Special Ability status effect that lasts for 30 seconds. During this 30 seconds, all spells and abilities that normally cost MP have 0 MP cost (as well as cannot be interrupted by damage).
This is especially helpful when the party is in dire straits and the Black Mage has run out of MP, but due to the high damage output of a Black Mage, it can mean that he will quickly gain a lot of enmity and in turn the attention of the enemy creature, and end up dying for the party.
Manafont now instead replenishes Shantotto's Bravery to its base value in an instant after she lands an HP attack.
One of Shantotto's cards can use Manafont. For the discard of a Shantotto card, Manafont removes the top card of the player's deck from the game, and for the rest of the turn the player can use that card's ability for no cost.
