Rare monster mod combinations...

Trucking along killing things pretty quickly with no issues for the most part.

But am I the only one running into rare monsters with mod combinations that make them literally impossible to kill?

i.e. resistance to both elements I'm running, life regen and minion revival.

My favorite one so far was two rares in a tiny space. One tanky one with invincibility aura and a dps one with the 'heals allies' perk and regenerate.

I managed to lure them out and separate them but they were literally unkillable together.

I've seen some very tough monsters.

Hasted + Proximal Tangibility + Mana Drain.

It's 'almost' impossible on an Archmage, but no it's not impossible, and I actually find them very rewarding to defeat.

Rares and Rare monster mod combos, as well as monster swarms including Rares and Magic monsters, are what keeps this game interesting and challenging. The occasional unkillable, or extremely-hard-to-kill, Rare monster is integral to overall game health.

Screw the unique bosses -- More time should be put into interesting Rare and Magic monster mods than those unique boss mechanics that eventually become predictable, tedious, and boring.
