Standard League - Hybrid Firestorm of Pelting Elementalist

Hey there,

i am playing this Lvl93 Hybrid Elementalist with Firestorm of Pelting and some Minions. I really like the Build eventhough its not very powerful :D. I do Blight most of the time anyway, which works fine.

I wonder now where to go with the last Passive Points. Any hints in that direction? Are there special Jewels, Clusterjewels or certain Unique Jewels, that could aid this line of build?

Thnx for some concrete tips.
