Quest: Save the Refugees. Kill the 3 leaders of the Goblin Camp.You need to kill the 3 leaders of the Goblin Camp (Joining Minthara and betraying her later doesn't work). When Zevlor offers you gold from the Tiefling refugee collection, you must accept and thank him. If you reject it, you also reject the Helmet.

Also .. as far as i know, Kagha never gives you anything ... unless you are Druid, then she make a staff for you and give you meaningless title that even ahe ignores later on. :-/
