If your finding Chaos runs better with Exile, look to the first line on the shield - 15% ctc Life Tap. The Oblivion Knights in A4 have a 33% drain effectiveness meaning your life leech only works at 33% under normal circumstances. With life tap that’s up to 100% effectiveness. Same thing for the ghosty mages and the big fire demons are at 66%. That’s why we usually go for a really high level of LL to overcome this.
The freeze target also goes a long ways to keeping you alive as your not taking damage from a frozen monster.
Exile for the Ubers means you can keep Laying of Hands in the gloves slot. As long as you have your resists from something else. Hoz can basically solve the resists issue. Then again I’m HC and resists are the world.
