As we now, elite monsters with the "[Health Link](https://gaming.stackexchange.com/questions/69957/how-does-health-link-work-exactly)" skill share part of the damage they receive with the rest of the monsters in their group.

Then there is also the "[Shielding](https://gaming.stackexchange.com/questions/68154/how-do-mobs-with-shielding-work)" skill, which makes the monsters immune to all damage for a short period of time.

With these two concepts clear, I have the following questions:

 1. What happens if a monster shielding itself (and with the "Health Link") is attacked? Will all damage (for all monsters) ignored or will only that monster not receive damage?
 2. If a monster with the "Health Link" skill receives damage and sends part of it to another one protecting himself with a shield, will this second monster receive any damage? Will it be shared at all?

In a similar fashion, the "Blood Clan Sorcerers" have the ability to cast a damage reduction shield. If a pack of these monsters has the "Health Link" skill and, say, all of them have a damage reduction shield except for one...

 3. Does it make a difference which monster you attack? If you attack a protected monster, will all the damage get reduced and then shared or the other way round?.

EDIT: As fbueckert and Adeese correctly mention, "Health Link" and "Shielding" cannot appear together in the same pack. The question about the "blood Clan Sorcerers", however, remains valid.
