Deathless Mastery

Type of Feat: Class

Prerequisite: Pale Master 10

Required for: None

Specifics: The character becomes immune to critical hits.

Use: Automatic

Immunity to critical hits includes immunity to Sneak Attack. However, prior to patch 1.66, Deathless Mastery did not provide that immunity. The bug has been fixed with patch 1.66 and Pale Masters are now correctly immune to sneak attacks (after level 10).
