This is my take on direct hit hexblast occultist in SSF. It uses some of the unique hexblast modifiers that are often overlooked. They enable chaos damage to shock and freeze and thanks to the cold mastery, the build can chill as well. It can also scale a different resistance other than chaos for damage output and that enables the use of Anomalous Frostbite for more maximum doom. This build was also indirectly buffed in the Lake of Kalandra, as we can reflect the doom modifier on the amulet for over 80% more damage for hexlblast direct hit.
