A sort of two-stage missile spell here. 'Greater Concealment' is not a spell associated with Ikonn or any supernatural entity; it was constructed by Azhog himself a long, long time ago and has not been used since before he became a doctor, or at all in this city - which is why he uses it now. He can be confident nobody can see through it. The spell provides mystical invisibility for 37 seconds - it's brief, but the invisibility effect is extremely potent and multi-layered.

Why not rely on the cloak, which functions equally well? Because Azhog is 'reprogramming' it (A pretty 'noisy' process, hence the extra cloaking); instead of not clearly perceiving or remembering the wearer of the cloak, without giving it a second thought, it will now cause anybody to perceive Azhog as his old self. Rather than just projecting an image - which would have led to brief story complication which has now been scrapped - it causes anyone to interpret any physical interaction with Azhog as fitting with the way he appears now. Since several of the races who inhabit the happy town could not only see, hear or feel a difference, but even smell the musk of a young Azhog from across a room, this is a very useful application.

Ikonn will demand compensation, but Azhog will pay it with pleasure, because he hasn't been to this temple of night clubs in over a week thanks to his now-captive.
