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.

Hard DEF

Effects of Hard DEF on incoming damage

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.

Hard defense has a base value of 0, and is increased by equipment, some skills, and items.

Additive Bonuses

Soft DEF

Soft defense, also known as "VIT" defense, reduces incoming physical damage directly.

SoftDEF      = (VIT ÷ 2) + Max[(VIT × 0.3), (VIT ^ 2 ÷ 150) − 1]
TotalSoftDEF = [(SoftDEF + BonusA) × (1 + BonusB ÷ 100)]
  • BonusA is the sum of additive bonuses.
  • BonusB is the sum of multiplicative bonuses.

At less than 50 VIT, every 10 points of VIT increases SoftDEF by 8. As VIT increases further, each point gives a larger bonus to SoftDEF.
