back in the days I played over 1 year doing almost only meph run. At the end I had over 800%mf.
And I always got @#!%ty items. Liek tal rasha ammy was a nice thing.
now I run with under 200%mf but I run for keys and I run in ilvl85 area (pit, museaum, chaos sanct, worldstone etc).
And after about a month 've found all by myself in solow games
4x gheed (2 of them turned into 36% and 38%MF ones
Vex 2x ist, um,pul,mal (I,m not conting hell forges)
38% ED / 15%ias jewel
afew 37% ED jewels
and various none magical item that I used soket quest to turn them into item that worth pul or +
magic %!*% just suk and its mostly cuz set and unci item suk (very few unic worth High runes)
Poeple want runes, charms, jewels and some rare soket item. These tiems worth high runes and these items aren,t based around any %MF.
The best thing I did in my D2 life wa to trow away MF tog et bether items and start running ilvl85 zones.
Doing mephysto you'r never going to find any item that worth HR (well I never got any after thousands of mephy kill back in the days).
