The idea is to convert all of Phys/Lightning/Cold to take as Fire using the following
Dawnbreaker (needs to be rolled to 20% cold/Light, Phys 15% at least)
Tempered by War (50% for Cold/Lightning)
Sublime Vision with PoF (30% for Cold/Lightning)
Cloak of Flames 40% (Lightning coil will brick this, because taking as lightning will kill us)
Helmet with 15+% Phys taken as Fire
Lethal Pride with 10+% Phys taken as Fire
Watchers Eye PoF for 10% Phys taken as Fire
ES/Arm Mastery for 10% Phys taken as Chaos. (We pick up CI so this is just free)
Now all damage is taken as Fire and we can just scale Max res to 85+ easily.
The biggest issue now is actually dealing damage since we are locked into uniques and sublime vision and timeless jewel. Since we are already using cloak of flame going ignite is probably the best route, and have included a generic Vaal arc ignite build. Please let me know if there can be any modifications or improvements to be made on this.
