soh's? well i wear one or more in one of mf hammerdin but still don't work! i found shitty dropps from bosses even i can boast his mf to 986mf cuz of Pgheeds40%, chance guard, etc. (although i switch gear for other important things not just mfding.)
as for u talkin bout when u let u zon wear it and do key hunting hhmmm it does sound possitive to me too, cuz i did try what u said and do key hunting and i do have found more keys than not wearing the soh. i dunno thu i think the soh is only for helping getting keys and thats the only thing it can do, cuz as of for now no one knows what soh can really do.

when i do countess, summoner, and nihlatak i possitively found more than 1 keys in every 1 or other game in a 1hr runs. with soh in stash countess drops 2 terror keys, 2 hates from summoner, and another 2 hates from nihlatak. and the best time i killed nihlatak he droped 2 destruction keys, and now i got 4 mules full of key sets and rest of the mules are random kind of keys. I'm too lazy to arrange them cuz i have a lot of fun doing key hunting now than doing mf for bulls**t. much better that way too.
