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
damage reduction. For example, if Defense is 200, the formula is
❈ Defense, the player takes 33% of the damage from monsters that would normally be taken with 0 defense.
or ~67% damage reduction, meaning with 200This 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
.
For example, if ❈ Defense is 200 and ❤ Health is 100, the formula is:
or
or
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.
