So heres a good place to start but I'm sure you have much better ideas and i want them badly.

Currently running
Kasim LVL 88
455 def Treachery
370ed Non eth Giant Thresher doing up to 535dmg and full res in hell.
A dirty little coif of glory blinds foos.

So better def treachery or even a stone or Fort would be ideal but realistically for now this is what I have.

Obedience could be put in a Eth thresher or CV for more dmg and better ED roll.

Helm I'm thinking about Andys for the Ias not sure what to sok it with as i dont need the res from a um or a ral....... Maby a Ias jewel don't they exist? (15/30 ias ed pretty sure)

Crown of thieves for the massive LL?

Giant skull for the CB not sure yet?

whats the next step for a fire druid merk i want to keep the CC from the Act 2 merk also obedience vital for immunes.

Maybe an eth reapers toll as weapon.
