Ark Knight

Ark Knight, also known as Arc Knight, is an enemy Job in Final Fantasy Tactics. This Job focuses on destroying opponent's morale, either by destroying statistics, equipment, or turning units against themselves.

Both Elmdore and Zalbaag have this Job. While their action abilities differ, they both have Vampire in their second slot. Zalbaag's job has an entirely different reaction abilities and support abilities compare to all "basic" job's found within the game. He can never learn Equip Axes, Beastmaster, Defend, and JP Boost because those were replaced with Counter, Concentration, Safeguard, and Swiftness.

There is also a version of Delita as an Arc Knight, via Gameshark, possessing the action ability is that of the Divine Knight.
