Zero link skill and %HP attacks?

Thought I had read it somewhere, but just did some searching and couldn't find any verification.
Does the Zero link skill have any effect on %HP attacks from bosses?

Or is it just a simple damage reduction?

I want to say no since I feel like it's useless at CRA...

It's just simple Damage Reduction. I see no difference at Gollux with it.

Yep, doesn't apply to % hp attacks at all, otherwise we'd survive 100% hp attacks.

Yep, damage reduction, which does not affect %HP attacks. My Zero and Xenon both take the full hit of Gollux's 50% attacks.

I wonder if it affects reflected damage from DR?

I think the Link Skill suffers from whatever the I/L Absolute Zero (Ice) Aura suffers from. In KMS, or at least in some of the videos I've seen, 1/1s actually get reduced by 20%, in GMS it has never had that quality.
