Build is still getting tweaked on gear, basically tried to make it as tanky as humanly possible since we have no flasks or leech sustain. Brittle is utilized on block of AG and through brittle ground on his Boots so its added to one of the grand spectrum jewels that is edited to give the proper stats to minions (the minion crit damage doesnt actually apply from these jewels by default so I hand jammed the value I get from it into the same jewel as the crit from brittle).
With the proper colors on my chest I replace hypothermia with increased crit strikes to get the average hit up to 4 million. Build is less inconsistent the more quality you have on phantasmal desecrate since non flickershade monsters usually do next to no damage, with an ashes of the stars the dps would likely go up dramatically since id sit around 90% chance to summon flickershade. Soul's Wick disables spectre banking on desecrate so we use phantasmal desecrate to manage the issue.
