Just curious what others have experienced here- I've killed oryx on hard 15 times (5x on 3 characters ) and I've gotten 0 hard mode helmets so far- are others in this situation too or am I just very unlucky? Edit: updated my completion count for the helpful member of the community below. Edit 2: Sounds like the conventional wisdom (based on loot tables) is that the drop rate for HM helms is 1/15. Some very lucky souls below are at 1/6 or even 1/5 though- nice! Edit 3: after three more clears this week ( 18 total now) I just had two HM helms drop- up to a 1/9 rate now for me.
