I believe we figured out the issue with GM Ydiss.
I asked for more feedback from you Freydis because we had to spot the issue, not because I "didn't bother". First wave of testing and player feedback made it clear, the item is dropping.
The process you are doing helped us understand that you are hoping for the antithesis from a proc effect, assuming you are referring to the spell Storm of Dranik, where the spell description says "Storms created by Dranik protect you from spells and provide you a combat effect that stuns, damages and increases the hate of your target. This effect has a small, added bonus of antithesis."
Antithesis effect never triggered from procs and never will due to server code limitations (would be bad anyway considering proc rates). Saying that it was working before simply means you were either using the antithesis given as part of the zone quest line or any other item that cast it (click effect, not a proc).
So the issue in this case is the spell description which is indeed misleading. This is true BTW for all procc effects that states the same. This is our fault and the 'description bug' will be fixed eventually.
On a side note, keep in mind Freydis you are playing a free game made by enthusiasts and treating them like shit won't help (it doesn't work anywhere else either). Try to be nice and helpful when you are actually asking for help yourself.
