Using Eternal Youth and Blood Magic to overcome the skill cost of CoC

I want to shine some light on a technique I learned about lately.

With Eternal Youth energy shield recharge applies to life recharge: https://www.youtube.com/watch?v=2pUncJf2WRg

If you have enough energy shield and Corruscating Elixir (chaos damage does not bypass energy shield) you never take direct damage to life and thus your life recharge never stops. The PoB below shows it in detail.

The culprit of most cast on crit setups is the mana consumption. It can be fixed with Sanctuary of Thought/Mageblood but holy cow that is expensive.

If you are running a low-life high energy shield cast on crit build there can be another approach to fix the mana problems using Eternal Youth and Blood Magic.

With Blood Magic all skills cost life and all auras reserve life.

With Enlighten 3 you and the life reservation efficiancy cluster you can have two 50% and a 35% aura on your life orb with sth life Precision on top.

Additionaly you can use another 50% aura with Eternal Blessing for free.

This still leaves you with enough unreserved life to cast any skill.

I made a special PoB for the setup: https://pobb.in/46ECWVyuT3N9

It shows a setup which has 10+ trigger rate per second and a life cost of over 1000 per second (100 per trigger). The PoB is just for the trigger rate and life cost per second.

With Discipline and Eternal Youth you can get over 3000 life recharge per second. More that enough to support any trigger.

If you can keep up your Coruscating Elixir with Traitor keystone that life recharge is never interrupted. With enough energy shield, energy shield regeneration rate and energy shield leech you recover your energy shield pool and thus never take damage to life.
