The fact accelerator decreases 30% defence, yet the highest defence a monster has is 20% PDRate, makes it completely worthless for dumping points into it. Those points could be put into something better like healing bot since it could potentially if used correctly lower your potion usage by a bit.

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.
