Getting advantage of Chieftan rework - Scorching Ray / Bodyswap tech

PoB - https://pobb.in/1V1PRLSVzm5D

Some commentary:

- up to 7-8 mil DPS, 1 mil eHP (well, 484k without Molten Shell), 75/50+ block, 2 automated curses, modest 5 auras

- mobile yet stationary playstyle similar to flicker strike builds, you can get ~100% uptime of Ramako's ascendancy, Arctic Armour and Inexorable benefits whenever you fight while not staying in one spot or being limited to your frostblink mobility

- easy way to get to 90 max res where all you need is purity of fire and at least +2 to max res somewhere on your equipment, the rest can come from the tree

- flexible gearing in general thanks to a lot of innate tankiness and 0 need of using same old exposure/flammability/ele weakness/scorch stacking so you can actually go for different curses, gloves and boots than your typical RF build

- no giga expensive items, watcher's eye, corrupted brass dome / your body armour of choice and the weapon are probably going to be the most expensive end-game items for you but still in <20 div territory

- enlighten lv 3 is enough if you go for uncrompromising notable on one of the small clusters instead of two mortifying aspects and prior to getting reservation efficiency enchant on the helmet you can spend 3-4 points in the Chapion of the Cause wheel to temporarily fix any of your reservation issues
