The Miriam Facer is a construct/guardian-type enemy from Final Fantasy XII found in the Stilshrine of Miriam. Like the Miriam Guardians, Miriam Facers are located along the walls and animate and attack the party as it passes. They also cannot be encountered after the player finishes the plot events in the Stilshrine.
Being the giant carven head of what must have been a truly gargantuan statue. Stationed as an eternal guardian to protect the Dynast-King's relics where they sleep in the Stilshrine of Miriam. It is not known by what power it propels itself through the corridors, but in that it represents the colossus's only surviving locomotive part, it seems likely that the head retains the source of the original statue's animation.
The Facers have high HP and normal attacks do little damage. However, they are susceptible to Wind, so Aero is useful. Quickening chains work, but in terms of MP in relation to damage done, Aero is more effective.
