Durability Question

So I got this crazy idea to make Eth Beast for my Blade Fury assassin.

I thought the weapons would not degrade when you don’t use them directly (like spells and such).

But while I was playing smiter I noticed it will reduce durability of a weapon, I am not sure if it’s because it uses procs or just benefits from the weapon.

So would Blade Fury & Sentinel also degrade durability?
