I have the european version of icewind dale 2. I have put in the code to get the decanter from nym ok. When i go to orricks tower in Kulderhar chapter 5 there is no air elemental how do i get it i have spoken to the son but it has no effect.
What am i doing wrong?

You should talk to a merchant for three times in a row, than air elemental should appear.

First you must look at something on the table behind what's-his-name, the son. Then you'll get a new dialog option to ask him about it (something about a strange language?). Then you ask him 3 times about it, and the air elemental will appear.
