Truth Is Beauty (3.5e Feat)
From D&D Wiki
 Perfect moment
All things that are true are pure and undamaged. Lies destroy all.
You are empowered to destroy those who cause you pain. Against any creature who is currently causing you pain through lying you gain a +4 bonus on attack rolls and a +4 on all saves. If you wrestled the truth from them these go up to +6.
You can feel lies, but not fight them.
