The Machinist has access to 127 licenses, which require 7,341 LP to unlock, as well as up to 9 additional licenses through summon licenses costing 780 LP, and 3 additional licenses costing 150 LP through Quickening licenses.
Machinist is a ranged class, using guns as their primary weapon, and can equip light armor. Machinists are versatile, able to attack from a distance and use some Time Magick. They can also use some Green Magicks, as well as equip measures and hand-bombs.
Machinists are ineffective against enemies that use guns and measures, and are unable to learn recovery magicks, as well as conditional stat boosting skills, such as Focus and Last Stand.
In The Zodiac Age the player can use two license boards for each party member. A good combination with Machinist is to couple it with a White Mage to gain a healer with lots of HP, three Swiftness licenses, eventual access to Hastega, and guns, which do damage regardless of the character's stats. Machinist-White Mage combination also allows the character to equip Dark Shot (Dark-elemental ammo) with Black Robes (boosts Dark-elemental damage by 50%). The player could also pair Machinist with the Red Battlemage. With Famfrit, this combination gains plenty of Time Magicks as well, only missing out on Haste, Berserk, Stop, and Bleed. Hastega surpasses Haste, and Berserk can also be achieved via an accessory or Bacchus's Wine. However, Famfrit is obtained very late in the game, at the end of the last mandatory dungeon.
If the player wants to get the most out of guns, coupling Machinist with jobs that give Adrenaline and Focus licenses are good, such as Foebreaker. The Machinist can do high damage, but guns never deal combo hits. However, the only shot that can be boosted with gear is Dark Shot with Black Robes, which requires the Mystic Armor 10 license to use and Adrenaline and Focus can also be achieved with accessories. Pairing Machinist with Uhlan allows the character to hit every element between spears and ammo and be able to play support when required with all the lores available.
