How do Lightning Rod's lucky shots really work ?

I am curious how Lightning rod and lucky shots work in general, mostly for the Lightning Rod passive atm...I've been told that if you have like 45% critical stricke chance (almost 1 out of 2 shots),lucky DOESN'T mean that you would get double the chance to have a hit calculated as a critical, although that's what I understand from it's description .. I thought that having 45%, it would make you crit basically 45% x 2 (- some diminishing return penalty).

Can someone please explain to me when this "lucky" applies ? The in-game tooltip gives a definition of it, but how does it really work ?

NON-CRITICAL HITS - NON-CRITICAL HITS - NON-CRITICAL HITS

Your chance to crit is not lucky, the damage value rolled of NON-crits is lucky.

Lightning damage has the broadest range from minimmum -> maximum damage per hit.

Other damage types will be like "7-20 more cold damage", while lightning will be something like "2-43 more lightning damage"

Lightning rod is very useful because with lightning damage a lucky non-crit can do significantly more than an 'unlucky' one- potentially even more than a lowballed crit.

Basically, it rolls your damage twice and then picks the highest number.

So if your light dmg is 1-1m
Roll1: 34k
Roll2: 670k

Your attack will do 670k instead of 34k.

This is the most simple of terms obviously.

Thanks for this, I read it and understood now. Haven't read the passive tooltip in a while and I forgot that there is a "non-critical" in the description. 😔

It's written in the PoE Wiki that the damage increase is about 1/6 of the difference betweeen max and min damage values of a spell, starting from 33% when min damage is 0 .
I am using Lightning Arrow on a Deadeye, and now I learned that Wild Storm (15% increased maximum Lightning damage) would boost Lightning Rod passive by a lot ! 😊
