Fox's Mettle (3.5e Feats)
From D&D Wiki
Prerequisite: Will or Fortitude save +2, Mask of Wraith
Benefit: a Fox of Sin can resist magical and unusual attacks with great willpower or fortitude. If she makes a successful Will or Fortitude save against an attack that normally would have a lesser effect on a successful save (such as any spell with a saving throw entry of Will half or Fortitude partial), she instead completely negates the effect.
This is a Modified version of a Hexblades Mettle ability to work with the Mask of Wrath.
