Defense

❈ Defense is one of the core player statistics. It determines how much Damage reduction the player has. The more ❈ Defense a player has, the less damage is taken from attacks.

Defense does not reduce ᚏ True Damage; that is reduced by ❂ True Defense.

Mechanics

Chart showing damage reduction.

The more ❈ Defense the player has, the less bonus damage reduction the player will have.

The formula for damage reduction is

${\frac {Def}{Def+100}}$ damage reduction. For example, if Defense is 200, the formula is

${\frac {200}{200+100}}={\frac {200}{300}}$ or ~67% damage reduction, meaning with 200 ❈ Defense, the player takes 33% of the damage from monsters that would normally be taken with 0 defense.

This leads to a misconception that higher ❈ Defense is useless because the damage reduction only goes up slightly. This is incorrect, for as the difference from 0% to 50% damage reduction may seem more substantial than the jump from 90% to 95%, both are equal in that they double EHP (Effective Health Points) (100-200 vs 1000–2000)

Effective Health

Main article: Effective Health

❤ Effective Health (EHP) is the amount of damage enemies need to deal to the player to kill them when ❈ Defense is factored in. If one has 100 ❤ Health and 200 ❈ Defense, they will be able to take 300 damage before dying, as shown below.

The formula for EHP is

$HP\times {\frac {Def+100}{100}}$ .

For example, if ❈ Defense is 200 and ❤ Health is 100, the formula is:

$100\times {\frac {200+100}{100}}$ or

$100\times {\frac {300}{100}}$ or

$100\times 3$ or

300 EHP, meaning with 100 ❤ Health and 200 ❈ Defense, the player can take as much damage without dying as someone who has 300 ❤ Health and 0 ❈ Defense could.

EHP is a useful metric for calculating which items are better than others in allowing the player to survive attacks.

EHP does not factor in ᚏ True Damage attacks, which are affected by ❂ True Defense.
