Under the Mage's influence, the Atronach boosts your Magicka and trains your Skill-at-Arms."
The Atronach in Elder Scrolls Online, is a minor constellation located within The Mage constellation. In the Champion System in Elder Scrolls, it provides the player with passive abilities that increase Weapon efficiency. There is also a Mundus Stone that when activated, increases Magicka Recovery.
Players may spend up to 100 points in each Passive Skill (Star) in this constellation, for a total of 400. Diminishing returns are a factor here. As the player puts more and more points into a star in this constellation they will get less and less benefit.
