Acolyte of Chayula

If I’m playing as an Acolyte of Chayula and use a spell that deals 100 fire damage with a hit, while having 100% increased elemental damage and the passive skill Reality Rending triggers (7% chance to gain 100% of damage with hits as extra chaos damage), plus I have 25% increased chaos damage from passive skills, how much total damage will I deal in the end? 450? And if I have 100% increased chaos damage from passive skills, will the total fire + chaos damage be 600?

We'll ignore the effect of the 7% chance on damage per second and assume that you've landed a hit that will cause additional chaos damage.

Calculations were made with this in mind

https://www.poe2wiki.net/wiki/Receiving_damage

You've landed 100 units of fire
Another 100 chaos units appear
You have 25%+100% Chaos damage increase, which is 125%
That means the total chaos damage is 225 units
You have a 100% increase damage from the elements, that is, from fire
That is, the total fire damage is 200 units
That means the total damage is 425 units

So extra chaos damage calculate from base spell damage without any increases for that type of damage from passive tree?

In PoE2-yes, this is how it works, according to the wiki. I believe.

As far as I remember, cross-amplification worked in PoE1.

Yes, but the answer you got above seems to be based on the PoE1 mechanics rather than the PoE2 mechanics.

Unlike in PoE1, stats/damage in PoE2 that are Converted (including "Gain X as Y" like you're asking about here) aren't affected by modifiers to the stat that they're converted from. Though, even in PoE1, it would've applied differently than you were asking.



Way it would have worked in PoE1:
100 Fire damage, 100% increased ele damage, 100% of damage gained as chaos damage, 25% increased Chaos damage
100 Fire damage * (1 + 1.00) = 200 Fire Damage
100 Chaos damage * (1 + 1.00 + 0.25) = 225 Chaos Damage
Final hit: 425 Damage

How it works in PoE2:
100 Fire damage, 100% increased ele damage, 100% of damage gained as chaos damage, 25% increased Chaos damage
100 Fire damage * (1 + 1.00) = 200 Fire Damage
100 Chaos damage * (1 + 0.25) = 125 Chaos Damage
Final hit: 325 Damage

Damage gained as a specific damage type only scales with modifiers to the new type, not with modifiers to the source damage's type (unless they're the same type).

You write correctly, but you count differently. The first calculation follows the described logic. Fire damage only has fire bonuses, Chaos damage only has chaos bonuses.

In the second calculation, you remove the 100% chaos bonus for some reason.

In the OP, two scenarios are asked, together with damage numbers that show how OP thought it would work: "would 25% increased chaos damage give me +50 chaos damage? would 100% increased chaos damage give me +200?"

An answer factoring in both the 25% increased chaos and the 100% increased chaos leaves some room for misunderstanding.

Oh, I was thinking there is one scenarios. In this case you are correct (We both, actually )))).
