EDIT: There is a mistake in a title - It's 71m TOTAL DAMAGE from ignite, actual dps is 9m, really sorry for a misinformation

I'm not even close to be an expert in build creation, just wanted to share my attempt at creating something of my own build (maybe as a starter). Any suggestions are welcome!

Concept:

• Replica Nebulis
  (15-20)% increased Cold Damage per 1% Missing Cold Resistance, up to a maximum of 300%
  (15-20)% increased Fire Damage per 1% Missing Fire Resistance, up to a maximum of 300%
  +600% increased elemental damage in total for Frostblink, which is insane multiplier
  The downside is the inability to have fire and ice resistance which we level out with a Font of Thunder and Divine Flesh keystone
• Font of Thunder
  40% of Cold Damage taken as Lightning Damage
  40% of Fire Damage taken as Lightning Damage
  +50% chance to be Shocked
  Unfortunately I couldn't find a way to be immune or be unaffected by shock besides flask with shock immunity
• Divine Flesh
  All Damage taken bypasses Energy Shield
  50% of Elemental Damage taken as Chaos Damage
  +5% to maximum Chaos Resistance
  I manage to do 87% max chaos resistance, but it's totally possible to make 90% with a small sacrifise of a damage

Summary, 90% of Cold and Fire damage is taken as Lightning and Chaos damage

The upside of this concept is that there is no need to collect Fire and Cold resistance

The big downside is that there might be a huge problem with elemental ailments such as ignite and cold DoT.

Important Uniques

• Bronn's Lithe - +5 level to a Frostblink + 90% inc damage - biggest increase of dps
• The Devouring Diadem - best helmet for accommodation of all important auras after reservation efficiency and Divine Blessing nerfEldritch battery keystone allows for easy use of Malediction + Divine blessing without Lifetap
• The Stampede - Cooldown recovery of Travel skills + additional annoitment

Optional Uniques

• Asenath's Gentle Touch - Temporal Chains + explodes = insane clear speed and + additional ailment duration
• Polaric Devastation - ash on hit
• Eye of Malice - budget helm
• Emberwake - not sure about this ring, might give even more dps

I think I wrote down all the essentials so if you have some suggestions for a build I would really appreciate it!

^(not sure what flair to put)
