Penetration (PV): Difference between revisions

{{tocright}}

'''PV''' or '''Penetration Value''' or {{PV}} is a value assigned to all weapons and plays a key part in damage calculation during attacking.

 

 

 

 

 

 

 

The PV of melee weapons is calculated as the follows:

** For non-vibro weapons, the base penetration bonus is equal to the weapon penetration value shown on the equipment screen in-game, minus 4. For example, if the weapon shows {{PV}}7, your base penetration bonus is 3. ''Typically this bonus is the same as your strength modifier (or your strength modifier + 1 for two-handed weapons), but it can be capped to a lower value depending on the weapon.''

** For [[:Category:Vibro_Weapons|vibro weapons]], the base penetration bonus is always equal to the defender's [[AV]].

* +1 bonus penetration if the weapon has the [[Sharp]] modification,

* +4 bonus penetration if the enemy is [[asleep]],

* +1 bonus penetration to swarmer attackers for each additional swarmer enemy that surrounds their opponent,

* and additional bonus penetration from the [[Charge]], [[Lunge]], [[Long Blade Proficiency]], [[Improved Aggressive Stance]], [[Shank]], or [[Slam]] skills as applicable.

A [[critical hit]] is guaranteed one penetration regardless of PV if the source of the critical hit is the player character.{{Code Reference|class=Combat|method=FireEvent|case="MeleeAttackWithWeapon"}}

==Ranged Weapon PV Calculation (Non-Bows)==

Ranged weapon PV is determined by the PV of the gun itself. The PV of the bullet does not matter and remains static no matter what ammo is loaded into the gun.

[[Critical hit]]s on ranged weapons add a flat +2 PV to the shot, increased to +4 if the weapon is a pistol and the user has [[Dead Shot]].

==Ranged Weapon PV Calculation (Bows)==

A bow's base PV is determined by the PV of the arrow loaded into the bow. The {{favilink|compound bow}} also has the effect of adding the wielder's [[strength]] modifier to the penetration value. The {{Favilink|turbow}} adds +4 PV to the shot and then adds the wielder's strength modifier to the penetration value.

# Start with a base penetration of 5.

# Add the thrower's [[modifier|Strength Modifier]], up to but not exceeding the PV ('''{{PV}}''') value shown on the thrown item in game.

#* A negative strength modifier cannot reduce this value below 5 for thrown weapons.

#* Objects that aren't explicitly thrown weapons have a maximum PV value of '''{{PV}}6'''.

# Minus 4 from the calculated total

#* Similar to melee weapons, the thrown weapon PV used for internal calculations is always 4 lower than what is displayed in game.

::{{Qud text|&amp;GStep 1a.i}} - Roll <code>1d10-2</code>. Each time that the maximum result of <code>8</code> is rolled, perform the <code>1d10-2</code> roll again and continue adding the results together.

:: {{Qud text|&amp;GStep 1a.ii}} - Calculate the '''maximum possible PV''' (what the attacker's PV would be without a Strength bonus cap on their weapon) for the weapon. Then, reduce it to the internal PV of the weapon (what is displayed minus 4) if it is greater. Add this value to the roll calculated in {{Qud text|&amp;gStep 1a.i|unbolded}}.

:{{Qud text|&amp;GStep 1b}} - If at least one '''''singlet''''' roll was greater than the target's AV, the attack penetrates one time (or one ''more'' time if this is a subsequent triplet). If all three '''''singlet''''' rolls were greater than the target's AV, reduce the '''maximum possible PV''' by 2, return to {{Qud text|&amp;gStep 1|unbolded}}, and perform another '''''triplet''''' of rolls to determine if the attack penetrates an additional time. ''(Continue this loop, reducing '''maximum possible PV''' by 2 each time, until at least one '''''singlet''''' fails to roll higher than the target's AV.)''

In summary, the attack penetrates and deals damage equal to its damage dice once for each '''''triplet''''' of rolls where at least one '''''singlet''''' was higher than the target's AV. <ref><code>XRL.Rules.Stat.RollDamagePenetrations()</code></ref>

The following chart shows the chances to penetrate against a creature depending on the relative value of attacker's PV versus the target's AV. Keep in mind that this chart corresponds to the internal PV value of a weapon. For example, the internal PV of a '''{{PV}}7''' weapon is '''3''', so a '''{{PV}}7''' weapon versus a creature with '''{{AV}}2''' would correspond to the '''+1 PV''' column of this chart. Similarly, the internal PV of a '''{{PV}}4''' weapon is '''0''', so a '''{{PV}}4''' weapon versus a creature with '''{{AV}}4''' would correspond to the '''-4 PV''' column of this chart.

In other words, when using this chart, assume the weapon has 4 less penetration than shown in the game UI.
