A question about catalysts

Hey dudes,

I stuck a load of catalysts (the ele dam ones whatever they're called) on my ring with +17% increased lightning damage. Ring displays quality at the top, advanced mod description just say (x% increased) after the mod.

My question is this. What did it actually do? The ring still says 17% increased lightning damage as it originally did. My DPS didn't change even 1 point (galvanic arrow 100% converted phys).

I had the same issue with prismatic catalysts and ele defence. Says 3% increased, did not change the amount of ele resist that I have?

I was under the impression that each catalyst gave 0.5% increase. So is this an increase to the increase or is it jut meant to raise the initial increase by x%?

Or am I just a total noob and I am completely misunderstanding how they work?

OK so the lightning dam seems to have actually worked. 6*catalysts gave me 1%. Not quite sure how that adds up or is even really worth it? 20 catalysts on a crafted ring for like 3.(3?)% increase? That's pathetic.

Ele resists still didn't change though? Did I gain like .01% of an ele resist?

Either way the entire catalyst system seems entirely underwhelming at the moment.

its literally 20% (if you get it to 20%), and the catalysts specifically say what they raise. AKA it will not raise both resistances and damage at the same time, those are different catalysts

It clearly says 0-20% (Depending on how many you use)

6% of 17 is 1.02...

Catalyst (definition): a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

So with a PoE catalyst, how quickly does it make you react in anger when you realize that the quality improvements are paltry?

It depends on the activation energy of your anger.
