The Sanctum Inquisitrix is an enemy that appears in Final Fantasy XIII.
This is the only enemy in Final Fantasy XIII that can cast Bravera, a stat-boosting spell that increases its target's strength by at least 80%.
The Evened Odds (SAB/SYN/MED), Bully (SAB/SYN/COM), Guerrilla (SAB/SYN/RAV), and Premeditation (SAB/SYN/SEN) paradigms prove useful, as they allow the party to debuff this enemy and power itself up simultaneously. The Dispelga technique can also be used to remove the Sanctum Inquisitrix's various buffs, but this should only be done as a last resort.
In the post-game, the Relentless Assault paradigm (RAV/COM/RAV) should be enough to defeat a Sanctum Inquisitrix.
