Last Build for 3.28 ; KBOC - which ascendency with mageblood?

Hello guys,

i want to play a last build for the remaining days. I still have a MB on my rf character and never played a kboc build before. on poe ninja its almost 50/50 who uses a MB.

What do you guys think? i dont know how many div i can put into the character in the remaining days... if i lowball my items rightnow i could maybe squeeze of around 150?! div or so, just to have fun in the next week.

So, hiero or necro?
