Oh that wasn't hard to find.
fw sorc works because its obnoxious and in many circumstances unstoppable. Your opponent can't stop you from doing what you want to do because you drain their life faster than they can drain yours.
If you're going to skip on fcr ammy, getting rep on the ammy is the most important thing so you can replace 2 armor or circlet pskulls for rare jewels or sol runes. The entire point of the char is to die slower.
Even if everything I had just said was complete bullshit and it turns out that I'm completely unqualified to talk about the build you know nothing about, you posted an ammy with low stats that gets beaten out by essentially every fireball amulet on the market.
Look at every esfb on your realm (or mine) and compare it to what you posted.
I picked this up today for next to nothing and I'll be giving it away free next month with another sorc I'm building. It's about on par with yours with low life, low mana and an extra 2-5 resist that doesn't help the build at all after the first 10.
If you find a 0 rep 0 fcr fw ammy and it has less than, say, 50 life and 60 mana then there's no reason to use it over a 2fire/15 rep or a 2fire/80 life ammy in the first place if you're looking to waste fg optimizing a build that could already win the duel with no amulet at all.
