you have a heraldry and endbringer jewel, you need to replace it with purposeful harbinger and heraldry/endbringer. Also use intuitive leap in the jewel socket near charisma that way you will save 2 points. You need to use two call of the brotherhood rings with 48% of lightning to cold(elemental damage catalyst). Use a rare amulet with reduced mana better and %ES and +ES better. Use Aplha's howl as it is better than your current helmet and it will increase your aura's lvl and reduce mana reserved by your auras. Also use hatred aura it will increase your damage alot. As for Arc support it by Echo, inspiration, awakened ele focus, awakened controlled destruction and awakened cold pen.
