Magic Defense is the total magical defense that is factored upon magic damage, which is generally based on MATK as whole or partially. However, there are exceptions.

The descriptions used here refer to Hard and Soft MDEF. These names are used for clarity. The vast majority of players do not use these terms in general conversation, and instead refer Armor Mdef (hard) and INT Mdef (soft). Hard MDEF works as a relative reduction, whereas Soft MDEF is a subtractive reduction.

Hard MDEF

Effects of Hard MDEF on incoming damage

Hard m. defense, also known as "armor" or "equipment" m. defense reduces, incoming magic damage multiplicatively.

  • Damage after Hard MDEF = Damage × [(1000 + HardMDEF) ÷ (1000 + HardMDEF × 10)]

For example, a player with a Hard MDEF of 60 will have incoming m. damage reduced by about ⅓, and a player with a Hard MDEF of 125 will have incoming damage reduced by half.

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

Soft MDEF

Soft magic defense, also known as "INT" magic defense, reduces incoming magic damage directly.

SoftMDEF      = INT + VIT ÷ 5 + DEX ÷ 5 + BaseLv ÷ 4
TotalSoftMDEF = [(SoftMDEF + BonusA) × (1 + BonusB ÷ 100)]
  • BonusA is the sum of additive bonuses.
  • BonusB is the sum of multiplicative bonuses.

Monsters use a different SoftMDEF formula.

SoftMDEF      = floor(Lvl ÷ 4) + floor (VIT ÷ 10) + floor(INT ÷ 5)
