Most of Aurelion Sol’s damage comes from his passive ability, a trio of stars which orbit him and deal damage to enemies caught in their path. The result is that Aurelion Sol provides a sizable threat to anyone nearby, and when coupled with his ability to fly over obstacles or nurse an exploding star as he carries it to its destination, he’ll require attention almost immediately when he shows up. Check out all of the details of his ability and how to make the best use of his kit on the preview page.
