@Gripphon Thanks a lot for the detailed analysis ... but ... Since I have only started this Sorc quite recently and her main aim is to get to 99, she lacks quite some items. No 3pc Tal's for example, as she has not found the armor or amulet yet. Also, no socketing, as I want to keep my socket quests for my endgame gear, which I haven't found yet.
So assuming Harmony on switch and aiming for the 63% fcr breakpoint, I see these 2 setups as possible options (variable mf% values between brackets, but from memory, I don't have access to my GoMule stash right now):
Setup 1:
Shako
Skin of the Vipermagi
CtA / Spirit
Goldwrap
Chance Guards (40%)
War Traveler (45%)
Dual Nagelring (25%/25%)
Amulet: not sure, but should get me some 20% mf I guess)
Gheeds (38%)
Setup 2:
Shako
4os Body Armor with 4 perfect topazes
HotO / Splendor
Goldwrap
Chance Guards (40%)
War Traveler (45%)
Dual Nagelring (25%/25%)
Amulet: crafted with 13+ fcr, probably some 10% mf as well
Gheeds (38%)
Setup 1 gives me 283 - 303% mf, with a range from 0 - 20% mf on the amulet, but 20% should be possible
Setup 2 gives me 369 - 379% mf, with a range from 0 - 10% mf on the amulet, not sure if I have one with mf% though
The second setup is definitely the winner in terms of mf%, but has less life, less resists (except for fire), less fhr and less flexibility in the amulet slot. So considering the fact that I can add quite some mf through small mf charms, the difference in effective mf% won't be so big, and I'm inclined to go with setup 1. I don't have that many small mf charms actually, but even then I should be able to get in the 400 - 450% range.
Of course, that is with my current gear. There is still some time left, so hopefully I'll still manage to improve my gear. The question is if I'll just continue running CS and hope to get some good drops at the same time (Jah and Ber for Enigma would be absolutely the best, other than that mainly Tal's armor and amulet I guess) or if I'll change targets to specifically hunt for certain items, like doing Mephisto for Skullder's Ire, Ali Baba or Arachnid's (which isn't mf specific in se, but opens up a lot of other combo's due to the fcr on it).
Another option of course is to try and level up a new Sorc in HC, where I do have items like Skullder's, Ali Baba, Gull, and the option to socket gear. But I'm not really keen on that one myself, as it would be a rush job and HC characters obviously can die, which would quite ruin the mfo for me ...
But I'll stop my ramblings here. I guess I mainly want to order my thoughts on the matter by writing it down. Suggestions are still welcome of course ...
@Grape I agree. Having a third person in our team would definitely be awesome.
