And Penetrated Armor more than quadruples triples it.
Nope, not at lower levels.
In order to get triple damage from PA, yonder mob's PMI has to be ~67%. And then you need to make sure your rapier* has got decent ADB, STR, proc % and duration... I'd rather not spend so much time, effort and money on it, quite frankly.
*because we're not referring to 2H/Niten here, obviously

You're supposed to use a Rapier with One-Handed and Dual Wielding. (IMG:[

Why? There are all these other weapons out there. TenB wants people to give them all a try, surely.
Maybe I *should*, but *supposed to* is a bit strong...

You just missed your chance to come back with, "But what about for people who don't use a Rapier for One-Handed/Dual Wielding." Same thing you said—who, in the right mind, isn't going to use a Rapier?
Not at all the same thing. I haven't heard of too many people using Niten - whether this is because they're in their right mind or not was not the focus of my question.
For one, I use a Club. Yes, it's slow, but damn! I'm close to invincible if I play right.
@Arxdewn:
Ceteris paribus, PMI reduces damage up to % of PMI you have. Therefore, the total damage getting through to the monster (assuming Void, therefore PMI is the only thing getting in your way) is (dmg)*1-PMI.
If I'm facing a monster with ~67% PMI, then the % of damage I'm doing is 100-PMI=32%. If I fully stacked PA, the total % of damage I'm doing is 100-0=100%, which is ~3x the damage I was doing without PA.
If the monster had 80% PMI, I would do 5x the damage I was doing without PA.
So doing your calculations is a bit tricky, because it depends on how fast I can proc a fully stacked PA, and how much PMI the mob I was facing had.
Which is why aurabolt is advocating the use of skills to proc PA at the beginning of the round. But given that skill procs activate prior to damage calculations, I would still advocate the use of SS to use a PA-proc Skill.
