Power attacks stamina cost?

[Sansidar]

I was wondering how the stamina cost works for power attacks in this game. Is the amount of stamina it takes to perform a power attack the exact same for every weapon in every tier as long as it is the same weapon type?

Or is it like Skyrim where a weapons weight affects the stamina cost of performing power attacks with said weapon?

Weight affects stamina, but in the base game stamina is completely a hundred percent useless, unless you have some mods that make the game harder. You can still power attack with no stamina, just your damage is reduced by a negligible amount, that there's no need to ever care about stamina except like the 2 fights in the game where you fight an unarmed dude
