Safeguard (メンテナンス, Mentenansu?), also known as Maintenance, is a support ability in Final Fantasy Tactics. The Chemist class learns it for 250 JP. All the equipments of the unit equipped with this ability will be impossible to remove, whether by stealing or destroying the equipment. It is especially useful against Knight units that frequently use Arts of War techniques.
It also appears in Final Fantasy Tactics Advance (as "Maintenance") and Final Fantasy Tactics A2: Grimoire of the Rift (As "Safeguard") and acts similarly. In Final Fantasy Tactics Advance it prevents breaking and theft of equipment and prevents theft of gil, Judge Points, Experience Points and abilities. It is learned by the Thief and Alchemist from the Adaman Vest for 300 AP.
In Final Fantasy Tactics A2 it prevents breaking and theft of equipment and keeps gil, items, loot, and Smash Gauge from being stolen. It is learned by Thieves and Alchemists from the Adamant Vest and by Vikings and Raptors from the Iron Armor.
