Zeus BM vs iphitos

[Spirit]

Hi, i'm a lvl 140 zeus player currently stuck on iphitos. I use a full BM build with zeus. I was wondering if anyone had any advice for certain setups for iphitos, because he is very tough even for BM. Not only can he take BM hits easily but the mage behind him decimates my heroes pretty quickly, leading to many losses. I was thinking of eurus/orion for some huge hits but i'm not sure if it will work. I have near max gear/washes but he is still a problem for me. I will post my heroes and gear below.

Heroes:
Zeus - lv. 140 renn 141 - 150/147/3 - +94 valor, +89 spirit --G(14)10 ares/zcloak
cronus - lvl 127 renn 141 -140/137/75 - +68 valor, +80 spirit --G(14)10 ares armor, G12(10) SOS
Anubis - lvl 140 renn 138 - 157/158/1 - +120 valor, +120 (+12) spirit - G(14)10 ares/mjolnir/kylin/zcloak
Sult - lvl 140 renn 141 - 150/151/47 - +120 valor, +120 spirit - G(14)10 ares/mjolnir/kylin/zcloak
hebe - lvl 131 renn 135 - 7/7/28 - G(10) 8 ares
oenomaus - lvl 111 renn 129 - 72/76/7

G(4) targe of achilles +681 valor shield
