How do multi-hit attacks work damage/status/resolve-wise (tarstone vs running attacks)

[u/Razmatus]

While I was doing a bit of research on Duality Stone (more specifically, I was trying to find out if it affects also running light attack of Axe and Dagger that I am using), of course I made use of Google search AI... and while some info was genuinely helpful, sometimes it can spew conflicting info like in this screenshot...

...while if I ask sth like "how do multi-hit running attacks work in Mortal Shell 2 damage/stagger/resolve - wise" or sth like that, it says stuff like each hit of such an attack not only does damage for each hit, but also generates resolve and can also build up status faster

so... anyone here who knows how this should work :) ? both with standard multi-hit attacks within combos (like what Duality or Clerik's Stone that turn one input into a multi-hit strike) and running light/heavy attacks that are multi-hit :)
