VIII. DETERMINING ARMOR RATING
===============================================================================
To determine your Armor Rating:
Monica21 & Elric_Melnibone
BaseAR * ( ArmorSkill / 30 )
This will give you the armor rating for an individual piece of armor. Assume a
character has a Light Armor skill of 91 and wears only Light Armor, all pieces
with a base AR of 50.
50 * ( 91 / 30 ) = 151.67 AR for each piece. The game will round this down, and
the individual AR will appear as 151.
To determine your total AR, multiply each armor piece by its weighted factor,
and then total them. The factors (shown as Percent of Total Armor Rating) are
actually listed incorrectly in the manual. Following are the correct weight
factors:
Cuirass - 30%
Shield - 10%
Helm - 10%
Greaves - 10%
Boots - 10%
RPauldron - 10%
LPauldron - 10%
RGauntlet/Bracer - 5%
LGauntlet/Bracer - 5%
(I tested these factors on my own character. Wearing just the cuirass, her AR
should have been 60 with a factor of 0.40, but it's actually 45, the same as if
the factor was 0.30.)
For the cuirass, multiply (151 * 0.30). This equals 45. Repeat for each piece
of armor you have equipped, and then total the numbers. If your character does
not wear a helm or equip a shield, the total AR will be 121.
NOTE: These numbers do not take into account how your Unarmored skill factors
in for any unarmored body parts, and the numbers also assume fully repaired
armor.
To determine your Unarmored Armor Rating:
( UnarmoredSkill * 0.10 ) * ( UnarmoredSkill * 0.065 )
Assuming that your Unarmored skill is 100, this will yield a max AR of 65, with
no armored body parts.
Armor Damage
To determine how much damage is absorbed and how much damage is taken, use the
following formula:
( Damage / ( Damage + AR ) ) * Damage
Assuming that a 25 point blow is landed and using the above armor rating,
( 25 / ( 25 + 121 ) ) * 25 = 4.28 damage to your health.
