All dmg from drowning orb bypass my energy shield in a CI build ( chaos inoculation )

I died too with by the Drowing Orb from created by the River Hag mob.
I had a Invoker lvl 95 in HC
I had CI with 15000 energy shield and the damage bypass all my energy shield .
Resolt :

- 0/1 life
- 15000/8000 Energy shield

This is very unfair because you doesn't realize what it is happening in some situation because there are a lot of mobs or you are in fron of the mob in a melee istance .
