Pretty low EHP. But it's ok if you do low MPs.
Swap to Amethyst on your voodoo mask if you need more HP.

You've got good AR.
I'd suggest to get a TWH without AR but with tons of life.

You look for a pair of rare pants with 140+ INT + 200+ VIT + AR + 2 sockets.

You're good to go. Should be able to do MP7-8.

What is TWH?

Yes, it's the witching hour.

You have good budget.
TWH is cheap nowadays, get TWH with VIT + life%
Look for rare pants with good INT + VIT + 2 sockets.

I checked your gears, it's the same as I last saw.

Upgrade belt to push up your dps.
Upgrade rare pants to push up your EHP.
I believe both will cost you not more than 500m.

If you still have gold to spend, go replace your Zuni's mask or ring with cc.
Last I checked, Zuni's voodoo mask and ring were pretty cheap. Harga runtuh.

Better DPS and EHP now.
Change your belt to TWH will give you more DPS.

Walk in the park @ MP0-5
Doable @ MP6-8.
