Rein's general fixes changes razorwire to apply bleeds instead and because barbed wire also uses the razorwire orb, it applies bleed and it no longer scales in damage on stacking the item.
I've also notified Rein and he said this:
"So what I can do on my end is incorporate the damage multiplier of the proc into the bleed multiplier somehow.
That way barbed wire will scale at least.
If ThinkInvis would prefer it to not interact, he would need to switch from reusing the orb to a custom one
Since there is no way to distinguish between a razor wire orb and a barbed wire orb"
