The Sanctum Templar is an enemy in Final Fantasy XIII encountered in the Tesseracts of Orphan's Cradle. It takes half damage from all elements, although can be inflicted with Imperil. The Templars can't be fought in post-game after the player defeats the final boss, because the section they are fought in can no longer be accessed. The Templars drop Perovskite catalysts rarely.
It is possible to cast both Pain and Fog on them simultaneously, although both have rather low success rates. The battle can be annoying and long, because the Templars are strong, but being at the end of the game, the player can use whatever Deceptisols they have left to preemptive the Templars. The Templars are capable of removing the party's buffs. However, as they keep doing it, the player can deploy a Synergist as a means of drawing their attention from using offensive attacks. The best tactic is to stagger them quickly with Ravagers.
Knights Templar were among the most wealthy and powerful of the Western Christian military orders and among the most prominent actors of the Christian finance. The organisation existed for nearly two centuries during the Middle Ages. Templar knights, in their distinctive white mantles with a red cross, were among the most skilled fighting units of the Crusades. They held great power throughout Europe before being forcibly dissolved through violence by Phillip IV of France in an attempt to attack the papacy. Pope Clement V tried to protect them, but failed. Nowadays, the Order of the Knights Templar is subject to numerous myths and legends.
