I’m sorry if this have been brought before, but this item Gulgazor Heart (https://www.grimtools.com/db/items/11368) is specifically made for Acid Inquisitor, meanwhile when making an acid Inquisitor the best set come to mind would be Radaggan Folly set (https://www.grimtools.com/db/itemsets/138) due to its acid and vitality RR.
But Radaggan and Gulgazor occupy the amulet slot, using Gulgazor will make Inquisitor not getting benefit from the 4th set bonus from Radaggan, and there is no reason for acid Inquisitor using Radaggan if it cannot getting that acid and vitality RR from the set.
I propose to change either the Gulgazor or Radaggan amulet into other slot (ring or medal?) OR swap the acid and vit RR from the 4th set bonus with the -80 OA/DA skill modifier on Radaggan mask.
