I'm stuck. I don't know what items i need, and which can be sacrificed.

My head slot is my wis +6 item now, but I also have a +6 wis necklace.

So far gear is:

Icy rainments
+8 bracers
immunity goggles(will swap with Tharnes when i can find - basicly the problem. What do I move around once I get tharnes?)
Spec gloves(will swap for +6 dex or titans grip when I get thranes)
+30% striders/+15 jump boots(Swap as needed, reach capped jump with little or no magic this way, also have feather fallers as needed)
Cloaks are collection of 30 resists and +6 cha, and +5 res/prot gear, switch as needed(Mostly am using resist gear since rainments gives both prot/res)
Neak is silver flame trinket(deathblock, considered making GS immunity neck item to replace, but if i get minos...)
Head is +6 wis hat(Considered GS heavy fort item later, and minos for now, which would bump the +6 wis slot down to neck)
Both ring slots are reserved for chattering and +natural armor - ring of balance or the ring from DQ raid, seal of earth -(switch out for +6 str/+6 con when barkskin pots or ranger around)
Belt at this time is +4 con, heavy fort, will replace with either +6 con or +6 str depending on what i have available, when I decide to get minos or not.

So help me out here, what should this toons immunity item be, what would be the least 'useful' spot i have to fill with it? (I Have JUST enough ing to craft 1 single GS item, so do not want to waste.)
