Myles' Mechanic Guide

I've heard mixed things about this. Does this, along with other defense reduction skills, reduce the monsters defense by 30 PDR, or by 30% (aka by a flat number or by a percentage)? -30 PDR would result in, let's say, a monster with 50 PDR would result in 20 PDR. -30% would be different, such as multplying the monsters def by 0.7, resulting in 35 PDR.

I used to think the prior, but the latter makes so much more sense.

I'm pretty sure it reduces it by the set number, such as 50 PDR would result in 20 PDR. That's how it is with my bowmaster with Marksmanship (-20% Defence)
