Yeah, my rebuild is going to contain considerably more FRW, I get 1660 life and that's far more then I need in any situation.
Stash Gear:
Stealth Ring Mail - I use this with rhyme against cold sorcs. FRW, enough FCR.
Rhyme Bone Shield - Pretty self explanatory.
Fcr/Mana/Cold Res ring - This is more of a temp, ladder switched over so I never bothered looking for a better ring, I use this to make up the fcr lost from the Wall of the Eyeless when I want a blocking shield.
Hel'd Whistan's - I neglected to build in the strength for whistans (whoops!) so I decided to hel it and meant to get a nice jewel later. You're looking for a -req, +dex jewel (you can build around dex on the shield since its the blocking shield)
For a rebuild:
As mentioned, I'd replace quite a few lifer charms for FRW charms. My original reasoning was that in any fight you'd want lots of FRW in you're pretty screwed anyway, and while true it's still nice to go down fighting.
I'd get a lot more stash gear, I honestly think a number of switch items are key for facing off against good duelers. I'd get a FHR/Life/Res belt (no strength, you'll still want a SoE) for fighting casters and replace the Shael'd Viper with a Pskull'd Viper. Make the Stealth in a Light Plate (looks better) and get a better FCR ring.
