T16 Mesa Exarch Map (the target early farm): https://youtu.be/YnUCpbH24mo

This pob is getting around 3-4m single target DPS (depending on if you have Diamond Flask enabled and how you spend last 4-5 pts) with a conservative config on around 5 divine cost at current prices. A few more videos posted from this build perspective in the channel. Build is designed to be an early league eldritch/essence/harvest farm character on a boss rush map like Mesa etc. I posted before league start but I wanted to put something out with updated Determination/Defiance Banner shell.

E: For those looking for a little more single target ouput (up to much more depending on how many you add) you can consider these options + the accompanying reconfig to support resists/131 intelligence etc:

-self roll shaper ring; unset base 10-15c and 1c per screaming essence of spite—looking for intelligence/life/resists and an open prefix to bench craft “non-channeling skills have -x total mana cost” + decent mark of the elder + attack catalysts ~30c. Replace glove eater implicit with exposure (about 1:30 in at 1-1.5c per mini ichor) and drop frost Bomb gem to alleviate socket pressure. Probably swap multistrike for inspiration but not mandatory, Replica Conqeuror’s efficiency can help (~35c)

-Awakened Added Cold Damage 20-30c for base gem, level it yourself or spend more

-Awakened Elemental Damage with Attacks: ~3-3.5 divine for base gem, level it yourself or spend more

-Bottled Faith: 4-5 divine, replace Diamond flask (alternatively you could craft a Sulphur flask with charges when hit and attack speed for ~20c)

-Large Thread of Hope + rampart: 1 divine

-Phantasmal Ancestral Protector - 150c

Alternatively, you can try to fit Blood Rage (I dropped it and some point because i didn’t want to fit in regen and the damage from it puts you in bad spots for shit like wrath of the cosmos farm). With these changes, a few more levels and Lethality or Dismembering wheel, (without the Bottled Faith) we’re looking at around 5-7m DPS (without/with flasks) on 10-12 divine (the more shit you craft yourself with essence/harvest the more you save), so about double the 5divine budget single target damage.
