Major problem dealing with Abyssal rares

They seem to often have a combination of 'invulnerable unless you're standing in their green aura' whatever that's called. And a passive phys damage aura that cant be evaded or negated by armour, and a healing flask supression aura.

It's been an issue since Abyssal was first added.

I have to get close to damage but doing so drains my health at high speed and stops me from healing.

Im putting this here honestly in hope some wiz comes in and tells me what I'm doing wrong. How my Melee/Armour/Es build can deal with the damage?

Abyssal Depths are becoming unpleasant because of this frequent interaction that kills me way more often than it doesn't.
