Do mobs or bosses ever have elemental penetration?

I am wondering if it is ever beneficial to be above the resistance cap to mitigate additional enemy elemental damage that they could possibly do through fire/lightning/cold penetration, aside from a curse, which could temporarily lower you below the resistance cap. There is so much in this game that is never explained, people don't know and have never bothered to ask or discuss, and GGG has never answered, nor is the answer ever described in any PoE wiki.

Like those tentacle fire things in Level 3 Lunaris, do they have fire penetration? Does Piety's lightning have lightning penetration?

That's not how penetration works. Penetration lowers your current resist.
When you have 200% resist, your current resist is 75% unless you're raising your cap.

The titty bitches are half fire, half physical.

Nah bro. Say you have 100% resist, and your resist is actually 75% because you have no purity or elemental adaptation, which would raise the cap. Say piety has 35% lightning penetration on her attack. Your actual resist to her lightning would be 65%. If you had 110%, you would have 75% on that attack.

That is how it works with mobs. Supposedly there are, or can be mobs that have over 75% resist. We never know because it never tells us, but if they do, that is how EE, penetration, and curses work. You don't start to see a difference until you take the mob below 75%.

But to my knowledge, we have never ever been told if any mobs have penetration on their attacks to nullify our resistance, which we could still resist by being over the cap.

Some curses lower the resistances of their target. These curses are:

Elemental Weakness: -% to All Resistances
Conductivity: -% to Lightning Resistance
Flammability: -% to Fire Resistance
Frostbite: -% to Cold Resistance

These curses will reduce the target's resistance. If a monster has 75% resistance and is affected by a -40% resistance curse it will have 35% resistance. If a monster has 120% resistance (by way of auras or rare monster affixes), it will be capped at 75%, and upon being hit with a -40% curse, it will be reduced to 80% resistance and still be at the 75% cap.

Some support gems will cause supported skills to ignore a portion of target resistance. These are:

Lightning Penetration: Ignores % of Lightning Resistance
Fire Penetration: Ignores % of Fire Resistance
Cold Penetration: Ignores % of Cold Resistance

These support gems reduced the actual resistance of a monster, or the resistance that a monster has at the point of damage. If a monster has 75% resistance and is affected by a 40% penetration support gem it will have 35% resistance, as with a curse. If a monster has 120% resistance, it will be capped at 75%, and for the purpose of the penetration support gems, its resistance will be 75%, not 120%. So a 40% penetration gem will reduce the resistance to 35% (which differs from the effect of curses). [1]

Both curses and penetration gems can reduce the resistance of a target below 0%.

It looks like you are right about the penetration portion.

So if that is true, and enemies have elemental penetration, why did Elemental Adaptation need to be nerfed? It is because with saffell's frame, it trivialized reflect or righteous fire?

Also what is the maximum amount of resistance a mob can have?

I don't think any mobs have penetration, becuase it would be listed under their name: "Penetrates X Resistance".

If mobs DO have penetration and it isn't listed, that's a very bad thing.
