Effect per rank
- Requires 16 points in Defense
- Due to how this mastery only scales with bonus armor and magic resistance, champions who gain large amounts of armor and magic resist from their abilities, such as Rammus, Galio, and Leona, gain the most benefit from this mastery.
- This mastery does not affect Thresh's Damnation as armor granted from that ability counts as his base armor.
