You need to boost your crit chance and crit damage alot.
Get a pair of Lacunis with CHC. Use your witching hour.
I myself ran with 5 set Immortal King for long but cut that.
Get a nice pair of gloves with IAS, CHD and CHC and use you Ice Climbers or get ones with run speed if you want that.
And with your budget, find a weapon with a socket to get double emeralds in your weapons, and go for 100%. Preferably a EF to get the extra attacks/second.
You have a long way to go to get to 200k but with that budget it should not be that big a problem i think.
I got 152k with dual wield and no money, what can you do with a 100k and 400mil budget?
Good luck m8!
