Well that sorc I have has 86% FHR and i rarely get interrupted on my Zealing. Besides if you hit her wit ha zealot your basiclly going to kill yourself since I am making her the "Stronghold" Build". I pretty much maxed out all my armors and gave her 4k Physical Damage +600ish fire and maxed out my Cold Mastey. SO when you hit her, her shiver armor retaliates a nice 3.5k damage Ice Effect when Cold Mastery is factored in. So zeal me once, your gonna die.
