Poisoners bow that lengthens psn time adds how much time? Elem or phys damage on bow?

I have 2 quick questions about Bows for my RANGER/NECRO.

I found a Poisoners Bow that says lengthens psn time and reduces time you are affected. If I use APPLY PSN skill any idea how much time it adds? or reduces when i'm poisoned?

2nd Question, I've seen some ppl using a bow that has like 15-28 Fire damage or lightning damage now how does this compare to 15-28 Physical damage?? Many Ranger skills have 20% armor penetration, i'm assuming that applies to their armor against physical attacks....? or just any armor including elements?

I do not know how long Poisoner's effect lasts.

Elemental damage is pretty much the same as normal damage, except it may do more damage to some players/monsters and less damage to other players/monsters. The 20% penetration will work with both physical and elemental weapon damage.

anyone know? darn i can't find this info anywhere. I was thinking this would be a good bow to pull and psn then switch to my SHOCKING SHORT BOW OF WARDING once they get closer

AFAIK Poisoner's adds about 20-25% poison time. I do exactly as you have said - I have a Poisoner's longbow that I pull & poison with, then I have a variety of shortbows and halfmoons that I switch to for the close-range wetwork. I can tell you it works great, and I have a tip if you are using Apply poison - sometimes with a longbow it can be hard to poison enemies because they are running around and dodging or blocking; when they do this pop off a distracting shot - it moves faster and seems to be blocked a lot less. Or, if you have another skill equipped that is unblockable/evadable, that would work too.

BTW anyone know if Apply psn would stack with Necro skill ROTTING FLESH? which diseases a creature and spreads it to nearby foes for around 11 seconds or so. Currently I either use ROtting Flesh/ Ingite arrow on a mob or APPLY psn and whatever, but would Rotting flesh on a mob, then APPLY psn'ing them stack or no? I know you can't double psn you have to wait for it to wear off but not sure about disease.

I believe they do stack as poison and disease are serperate conditions

how do you have 20% armour penetration?

i said that some of the ranger skills, such as Penetrating arrow have 20% armor penetration that combined with Weaken armor, Necro skills, hunters shot to get them bleeding while running at you, and the psn , and dust trap should be able to beat a warrior.

Monk spell, Judges Insight also has 20% armor pen, and converts all your dmg to holy dmg (undead hate it, you should have seen my arrow attacks maul the lich )
