Chakram - take the Legend Mythology, empty Socket, & Epic Whirling Blades off and replace them with Epic +100% Weapon Damage, +5000 Weapon Damage, and +40% MP Reduce (this will reduce the cost of using skills on your MH)
Mirror - take off the Epic +5000 Weapon Damage and put on +40% MP Reduce (reduce the cost of using skills on your OH).
Head - take off the empty Socket and put Epic Whirling Blades +10. take off Legend Pick Up Radius and put your choice of either Epic +30% Weaken, Epic +15% Cooldown, or +20% Poison Damage.
Ring - take off the Legend +All Skills & +All Talents and put on Epic +10 Crit Chance and Epic +75% Crit Damage.
Amulet - take off Haunting Set and Legend Resource cost and put on +30% Weaken and +15% Cooldown.
if you don’t want Cooldown at all, then use +20% Poison Damage instead.
Pet - use Calcite to change the Pets Element to Poison. for all of the Normal (Yellow) affixes, take them off one at a time. use Angelite to put an Epic affix on for each Normal you take off. then take them off one at a time while replacing them with Angelite until you have Epic versions of all the Normal affixes. the Shock Resist should be changed to Epic +30% Weaken.
on higher floors, Dodge, Block, and Sanctuary Mythic are better than HP, Armor, Damage Reduction, All Resist.
Obsidian Crystal to get Crystal affixes - it takes 3 Epic Crit Chace and 2 Death Natures with the base +10% Crit Chace to reach the +60% Crit Chance cap. that is 3 spaces. with 1 +45% Crit Chance, 2 Death Natures, and +10% Crit Chance to reach the same +60% cap, only 1 space, leaving 2 for other affixes. you can have 1 Crystal affix on each Item, but not the Pet.
hope this helps.
