Mundus Stones are special ritual objects located throughout Tamriel. They are dedicated to 13 different constellations, each with its own particular effect. As a character may only have one Mundus Stone blessing at any given time (unless wearing 5 pieces of the Twice-Born Set which allows for two blessings to be active), activating a different Mundus Stone will replace your current blessing.

You can increase the effects of Mundus Stone blessings by up to 7.5% for each piece of armor in the Divines trait.

Mundus Stone effects changed significantly with the Horns of the Reach update in August, 2017. Changes are shown below with the use of italics (added effect or new rate) and strikethrough (removed effect or old rate).
