Looking for an old adventure module – Heroes explore a tower and find a trapped wizard

I’m looking for an old adventure module and I can’t remember the name.

This is what I remember:

  • For AD&D 1e, and may have been a DM’s Guild publication

  • For low level characters, not more than 5th

  • Wizard is trapped in a magic circle and begs for help

  • One room is a "refrigerator" with a bound ice-elemental to keep it cold

  • One room has a pet basilisk, and anti-stoning spectacles hanging outside the door

  • Magical "elevator" that goes to every floor of the tower, and one floor is "secret"

  • I think the cover art was a B&W drawing of a lone medieval type tower, with lightning bolts flashing around it. The perspective has the viewer looking up at the tower from the ground level.
