This quest was extremely simple for me? Shouldn't your quest markers guide you to your objective? Make sure you have this quest active in your journal if it already isn't. That should point you in the right direction.

I know there is another one, not in the hall of countenance but that other hall with the beds.
And I think I remember that there are ones on the bridge to the College.

If you get really stuck, turn on quest markers

wen i click on the quest it dose not show me or lead me to the location...I Dunno if this is a Glitch on pc Version but suppose i can try clicking on this quest again

Tryed the ones on the bridge also But didnt get the Option to Click(E)

For misc. quests, you have to activate them twice in your journal for the markers to show.
You have to activate misc. quests themselves, and the quest you want to do.

Don't remember exactly, but isn't it the one in the main square, and then the two in the rooms left & right of the entrance to the square if you come from the bridge?

There's one in the main courtyard, one in the Hall of Countenance, and one in the Hall of Attainment (the apprentices' living quarters, on your left when you enter the college through the bridge).

How do i cleanse these focal points? I walk up to them and activate them but nothing happens.

you must also equip the mistic gloves too clean the focal points i hope thats the solution otherwise there,s something wrong
