DEF

Defense is the total physical defense that is factored upon physical damage, which is generally based on ATK as whole or partially. However, there are exceptions.
The descriptions used here refer to Hard and Soft DEF. These names are used for clarity. The vast majority of players do not use these terms in general conversation, and instead refer Armor Def (hard) and VIT Def (soft). Hard DEF works as a relative reduction, whereas Soft DEF is a subtractive reduction.
To obtain the final damage,apply Hard DEF first and then apply soft DEF.
It is shown as A + B in the Status Window, where A represents the Soft DEF and B represents the Hard DEF.
== Hard DEF ==
Hard defense, also known as "armor" or "equipment" defense reduces, incoming physical damage multiplicatively. 
* Damage after Hard DEF = Damage × [(4000 + HardDEF) ÷ (4000 + HardDEF × 10)]
For example, a player with a Hard DEF of 275 will have incoming damage reduced by about ⅓, and a player with a Hard DEF of 500 will have incoming damage reduced by half.
Being attacked by more than two monsters decreases Hard Defense and Soft Defense by 5% per every additional monster. When attacked by more than 21 monsters at once, both defense value is reduced by 100%.
Hard defense has a base value of 0, and is increased by equipment, some skills, and items.

== Soft DEF ==
Soft defense, also known as "VIT" defense, reduces incoming physical damage directly.
SoftDEF = floor((VIT ÷ 2) + (AGI ÷ 5) + (BaseLv ÷ 2))
TotalSoftDEF = [(SoftDEF + BonusA) × (1 + BonusB ÷ 100)]
* BonusA is the sum of additive bonuses.
* BonusB is the sum of multiplicative bonuses.
Monsters use a different SoftDEF formula.
SoftDEF = floor((VIT + BaseLvl) ÷ 2)

== Bypassing DEF ==
===Calculation===
 Final DEF = (Total_Def - Sum_DefReduceValues) × (1 − Sum_DefBypassPercent ÷ 100)
* Total_Def = Total Hard DEF shown in the Status Window.
* Sum_DefReduceValues = sum of flat values that reduce DEF, like Odin's Power.
* Sum_DefBypassPercent = sum of modifiers that bypass DEF by a percent, like Expiatio and .
*For example, if a player has 25% DEF Bypass from Expiatio buff, 30% DEF Bypass from Perverse Demon Mask[1], and Odin's Power Level 2 (-40 DEF) is casted on an enemy with 500 Hard DEF, the enemy's final DEF is calculated as:
**Final DEF = (500 - 40) x (1 - (25+30) ÷ 100) 
The skills and equipment below are known to either bypass DEF, or have a reversed effect, thus increasing damage from the amount it.
