How much damage does the Shaper's slam do?

Let's say I have 25k ES and no mitigations of any kind, 0 armour, no flasks fortify etc. For how much would I be hit? How about a critical strike hit?
I asked some people around and got different answers. One said ~11k other 10-12k other dude said that he got one shot when had no mitigations and 22k ES. To my understanding (which might be incorrect), by wiki shaper has 5689 hit damage, shaper's slam does 300% of the damage, but it doesn't say if it based on his hit damage or on somethings else. If to count this way, then 5689*3 = 17067 (regular shaper's slam damage)*1.3 (5% chance to crit with 130% multiplier) = 22187 shaper's slam crit damage before all mitigations. Is that correct? The main thing is that I don't know if 300% of the damage is based on hand attack or on something else. For example, his hand attack can be 150% of base damage or something and then the shaper's slam would be counted not by this 5689 attack hit but by some lower number. 22187 feels quite big.

Why am I interested? I am trying to make a shaper's slam tanker and trying to find out how much of defenses I need.

P.S. If I wrote in the incorrect thread, I am sorry, that's the best one I found.

Your calculation is correct from what i know. 17k normal damage and 22k with crit.

Thank you, looking for more people to confirm or oppose the numbers.

Basically high physical damage reduction\mitigation helps. If you would for example wear the Brass dome so you cannot be critted you would need about 60k armour at 4.5k life\es to not die roughly.

Yes, I do know that. I am looking for exact numbers to find out how much of mitigations I need to not over invest into durability.

If we are talking about 17K physical damage hit these numbers are incorrect (checked in PoB).
PoB shows only ~30% mitigation with 60K armour vs 17K physical hit.
(Btw he has other sources of PDR in his video such as fortify …)

I am not sure Shaper deals pure physical damage in his slam though (it would change data dramatically).
His slam also deals more damage in the centre of his slam (from my experience) so harder to test/collect data.
It should be possible to test it though by using extreme physical damage mitigation (closer to 100% better) with minimum chaos/ele res (it would need lots of testing though unless you just want to test it´s not pure physical hit).

More and more different answers. Thank you
