Locate and speak to Drevis Neloren. Ask him if there’s anything the College needs. Agree to help him cleanse the Magic Points and you’ll receive the Mystic Tuning Gloves . Equip them and now you got markers on all focal points . Go to each point and activate them.
There are 3 in total; one in each hall and one outside. These can do a random thing to you, from breaking an item, filling a Soul Gem, or harming you. Be careful. Once you’ve activated all 3, return to Drevis. He thanks you and removes the gloves… and that’s it. You don’t get anything. LAME!
