Ancient Knowledge is an ability found in The Elder Scrolls V: Skyrim.


It is a reward for completing the quest Unfathomable Depths.


Knowledge gained from the Lexicon confers a 25% defense bonus when wearing Dwarven armor and Smithing increases 15% faster.


  • With the 25% bonus, a fully-upgraded set of Dwarven Armor can give a slightly higher armor rating than fully-upgraded Ebony Armor, depending on the skill.confirmation needed
