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 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.

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)
The equipment below are known to bypass MDEF.
||Bypass 100% of hard magic defense of normal monsters when performing a magical attack.|
||When compounded to a Rod, Int +1 and ignores 2% of the MDEF of enemies.|
||Bypass 30% of hard magic defense of Boss monsters when performing a magical attack.|
