Black Magicks (Final Fantasy XII)

Due to the lack of job classes in Final Fantasy XII, all characters are able to learn Black Magick by buying the appropriate license on the License Board.

Damage calculation:
 * $$DMG = [POW x RANDOM(1~1.125) - MDEF] x [2 + MAG x (Lv+MAG)/256)]$$

The damage is boosted if the caster is affected by Faith, wears equipment with Elemental Affinity, the current weather or terrain boosts the effectiveness of the used element, what augments have been purchased on the License Board, and whether the enemy is weak against the used element.

Abilities
MP cost is defined as default MP cost. Channeling Augments lower MP cost of any spell.

International Zodiac Job System
Black Magick has been added with status effect spells from the Green Magick category. The job Black Mage has access to all spells. Other jobs have limited access:
 * Uhlan can access Level 5 and 6 with a Quickening License and Level 7 and 8 with the Esper Chaos License.
 * Red Mages can learn Level 3 to 6 spells and access Level 9 and 10 through the Esper Cúchulainn License.

The success rate of negative status spells are unaffected by the target's magick evasion.
 * $$Success Rate = Base Rate + (MAG of user - VIT of target) \%$$

If the target has Shell, the success rate is halved.
