In version 2.4.1 I found two copies of Nilfur's Boast boots. I extracted the bonus from one and wore the other.

Patch 2.4.2 modified those boots, and this immediately changed my cubed copy but not my physical copy.

If I wear my old boots and cube the bonus from the new versions, do the two stack or does only one version count? And if only one versions counts, which one is it?

    You're in the perfect position to test this out. Let us know once you find out :)

  • Did you end up testing it out?

    @Riley pretty sure it doesn't stack, but my testing wasn't comprehensive.

  • No, they don't stack. As to which one gets used and which one gets ignored, I'm not sure.

I can now confirm that not only do they NOT stack, but also that only the bonus from your old boots will take effect!

It seems that the bonus effect from Kanai Cube will be disabled if you also have the same item equipped on your body. So in your case, you will only have 100% damage increase (not 350% or 450%) if you equip those old boots!

So if want the 350% damage increase, you cannot equip the old boots on your character.
