PoE dotahousecat builds

Hi, I've been trying to build around a Herald Thunder autobomber (HoT), using a mana-stacker approach, by combining the "Essence Glutton" necro node via forbbiden jewels (2% base mana/s) and Elementalists (1% base mana/s) from "Mastermind of discord" and Agnostic\ to sustain both life and mana. \Agnostic is provided via Sanctified relic, so it's added under custom modifiers. HoT is in the Crest of Desire to minimize the mana reservation. Build is so far decent for clearing t16 maps - the sustain is GREAT compared
