Not sure this is the right place... But whatever - i want to more people try this and share their opinions.
After countless sleepless night in thoughts about PENETRATION i've changed my mod. But let's start from far - i want to explain what downsides of vanilla system was fixed.
There is a several scenarios in vanilla that looks...far from perfect (in my opinion, of course).
#1. Balanced scenario, when Attacker's PEN = Defender's AR (which is not often). Attack deals listed damage (good for Attacker), but Defender's armor not working (at this moment you thinking: "What for this armor needed?!") In fact, Armor just protect you from possible Overpenetration bonus damage.
Resolution: I remember PoE 1 system (which was far from perfect anyway), when armor always give some protection. So i've changed PEN=AR Damage - now attack deals only 75% damage (-25% Damage penalty). Even the Light Armor will reduce some damage and protect Defender from attack. Good for Defender, bad for Attacker you say, but...
#2. Attacker's PEN exeeds Defender's AR by 1 or 2 points or whole bunch of points, but less than x2 (13,5 Pen vs 7 AR etc.) In vanilla game Attacker gains nothing and armor still don't give any protection to Defender. Literally, there 2 breakpoints – PEN = AR and PEN = x2 AR – everything between gives nothing to both Defender and Attacker.
Resolution: Since game counts OVERPEN as PEN/AR ratio (which is not perfect but doable), i've added incrementing damage boost with 5% step. In vanilla you never care to change your weapon if PEN exeeds target's AR less than x2. Now you will want to do it to deal maximum damage. And vice versa. This how it looks:
x1.0 = 75% dmg (PEN = AR)
x1.2 = 80% dmg
x1.4 = 85% dmg
x1.6 = 90% dmg
x1.8 = 95% dmg
x2.0 = 100% dmg (PEN = x2 AR)
P.S. Now i running some tests - if all goes fine, i'll upload a new version with more precise damage calculation.
#3 (implies from #2). Bonus Damage from OVERPEN no longer exist. On Obsidian forums people often wondering, what is "Overpenetration" - probably, when your sword drivening through enemy stomach up to the hilt.
So, Attacker will deal full damage only when his PEN exeeds Defender's AR x2 or more. On one side, Attacker will be rewarded for every PEN point, on the other side Defender still receive some protection from armor, which reduces with higher Attacker's Penetration, so EVERY AR & PEN point will be working for both sides in every possible scenarios. Pure and simple.
Overall damage output for all charachers will be slightly reduced, but not drastically.
#4. Vanilla UNDERPEN damage penalties was changed. UNDERPEN 'window' slightly increased: from -1 to -5. When Attacker's PEN less than Defender's AR, Attacker receives additional -10% Damage penalty per point under the target's Armor, Max -75% at 5 points).
But you don't need to stack your AR to +5, becose even with PEN>AR Defender have moderate damage reduction. So overall incoming damage will be less than vanilla.
PEN > AR (PEN/AR ratio):
x2.0 = 100% dmg (vanilla: 130%)
x1.8 = -5% dmg (vanilla: 100%)
x1.6 = -10% dmg (vanilla: 100%)
x1.4 = -15% dmg (vanilla: 100%)
x1.2 = -20% dmg(vanilla: 100%)
x1.0 = -25% dmg (vanilla: 100%)
PEN < AR
-1 PEN: -35% dmg (vanilla: -25%)
-2 PEN: -45% dmg (vanilla: -50%)
-3 PEN: -55% dmg (vanilla: -75%)
-4 PEN: -65% dmg (vanilla: -75%)
-5 PEN: -75% dmg (vanilla: -75%)
So, this variant of Penetration system have several pros:
Light Armor and Clothing will be useful, even on POtD, and give protection not only from possible OverPen +30% bonus damage
Attacker gains reward for every Penetration point that exeeds Defender's AR
Every AR point for Defender will be rewarded and give additional protection even when Attacker's Pen exeeds AR less than x2
More smooth UnderPenetration damage penalty increment
Terminology slightly changed (including Cyclopedia entries and tooltips)
PEN < AR: No Penetration. 25-75% dmg.
PEN ≥ AR (but not x2): Partial Penetration. 75-95% dmg.
PEN = x2 AR: Full Penetration. 100% dmg.
