"One of the many brands of the machinist, the tinker wages battle with his clockwork creations."
—Description
Tinker is a Job in Final Fantasy Tactics A2: Grimoire of the Rift, only accessible to Moogles. This Job uses gadgets that have a 50% chance of either hitting every enemy or every ally, making them a very unreliable class; They can either be the player's best friend, or worst nightmare. They are somewhat similar in function to Calculators from Final Fantasy Tactics, in that they cast normally single-target spells on multiple units, albeit with restrictions.
Although they are risky to use, the Tinker's stat growths are superb, having high HP, Attack, and Defense, average Speed and Magic, but with perfect Resistance, only severely lacking in MP. Tinkers are best used only when the situation desperately calls for one, or at the start of a battle, when the game can be reset if the desired effect does not occur.
There are some ways to make Tinkers more useful. One such solution is to equip the entire party with items which make them immune to a certain status effect, then use an ability which causes it freely. In this case, even if the ailment is cast on allies, none of them will be affected. In addition, if an enemy party happens to be aided by a beneficial spell, as opposed to the player's team, Blue Screw is useful in removing the status from the enemies. Also one can use the Blue Mage's ability Roar to remove buffs given to the enemy, and can use the Summoner's ability Unicorn to remove debuffs.
They are also notoriously considered to be the worst job in the entire game, especially due to the mission "Time to act", where the Tinker will almost always Haste the enemy with Red Spring, usually allowing the enemy an immediate kill on one Moogle unit, causing the player to fail the mission. However, in a mission like clean the ship deck that has no Mimic or the Luck Trial, Red Spring and etc. will always be positive toward your party.
The head of the research team at Goug is a Tinker.
The TINKER crafts elaborate devices that wreak havoc on the battlefield.
Before the attack is issued, a box is opened, and the moogle face inside the box determines whether your allies or enemies are affected. An angelic moogle means that the ability will benefit the Tinker's team (i.e. positive statuses will affect its allies, while negative statuses will affect its enemies) while a purple, "evil" moogle means that the ability will benefit the Tinker's enemies.
Tinkers are absolute either spars with Green Mages or the total opposite of them. Since they are both casts buffs and debuffs, yet the Green Mages are magicks are area effect, and the Tinkers are determinable in their benefit two all allies or enemies since their abilities are all affiliation-based effect.
When used as a noun, a "tinker" is a person who repairs or attempts to repair machines and/or invents. As a verb, it means to attempt repairing or improving a machine; typically in an experimental or even haphazard manner.
