Please tell me what names of items needed?
Figure it by yourself. My advice is that there are more MP affixes than HP ones and that Bloodmagic Mythic convert all MP into HP.
read the dictionary for sets.
use more "Balance" Hp % set affix and Flat Hp 7500 . you can make 1.1m hp or 1.3m something like that. you can figure it out by reading on codex. take down notes all set affix . that boost hp .
The possibilities are endless on how to make 1m hp
Just read around forums and codex as others pointed out
git gud at thí game!!
