Tectonic slam of too late in the league (PoE 3.29)

Started this build a while ago, then learnt of weird nuances of POB vs in game vs wiki vs POEDB as well as the mechanics of Tectonic slam of Cataclysm Most sources say uber bosses have about 50 million HP POB has calculations for Uber Bosses however, 50 million damage is not an instant kill, that is actually closer to 300 million. Why none of this lines up, I have no idea, but what ever.

Basically I just wanted to figure out what was going on with tectonic slam of cataclysm and see why it always felt so trash.

The TLDR is that increases from endurance charges etc are calculated on hit, the consume is performed mid attack time, and the damage tick from echoes happens at the first frame of the attack. So basically what I did was get my attack time to the point where the next server tick, Enduring composure (and its friends) would tick roughly the tick after the charges are consumed, to make sure there was no downtime, and the increased damage calculation would then work when the slam travelled and connected with an enemy.

All of this so I didn't have to buy +1 corrupted endurance charge Ralakesh boots

here's the Trash POB - You'll want to make it better before playing it Also you can strip out all of the endurance charge generation and put on Ralakesh to have a way better time, and then use any weapon, go crit, blah blah blah all the better ways to play this build https://pobb.in/Ss422BNtzATK
