I couldn't solve phys mit, but it is very very rarely an issue given the amount of less damage we apply. Given that most environment effects are elemental in nature, going more elemental mit was much better than going more phys mit.
The build feels good and worth swapping to.

Estimated total cost of build (purchase price of items): 531d -- probably 600+d now for build

5. 5d anathema + catalysts [10d+ now]
6. 16d helical + spite essences
7. 30d ghost enchant [40-50d now]
8. self farmed ele weak enchant (maybe 1d)

As you can see items are more expensive as people are richer and transition to end-game variants. This phenomena is known as adam smith's invisible hand of the market coupled with inflation.
