Cham because I currently pick up a lot and those cold explosions otherwise slow me down too much.
Gripphon's Eye because it increases Static Field damage. Half the council is breakable LI and still has very high light res after Infinity. I once tried to theorycraft the right -ELR amount to maximize static damage. I concluded it's very hard if not impossible. Problem is you have to factor in random amounts of Blizzard shards hitting them, otherwise it would be easy. But definitely -ELR helps ofc, I just prefer the extra life/mana/BO and MF from Shako.
