❈ Defense is one of the core player stats. It determines how much ❁ Damage reduction the player has. The more ❈ Defense a player has, the less damage is taken from attacks. ❈ Defense can go 0, but that does not have have any special effect.

Defense does not reduce ✷ 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: ${\frac {\text{Def}}{{\text{Def}}+100}}$

For example, with 200 ❈ Defense , 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 (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: ${\text{HP}}\times {\frac {{\text{Def}}+100}{100}}$

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

$100 \times \frac{200 + 100}{100}$ or $100 \times \frac{300}{100}$ or $100 \times 3$ or

The result is 300 ❤ Effective Health, 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 ✷ True Damage attacks, which are affected by ❂ True Defense.

Increasing Base Defense

Players do not have any base ❈ Defense by default. It can be increased by:

• Leveling  Mining
• The Forbidden Defense upgrade in Wither Essence shop

Increasing Bonus Defense

There are several ways to gain additional bonus ❈ Defense. They include, but are not limited to:

• Equipping most types of Armor
• Holding certain weapons (e.g.  Golem Sword,  Earth Shard,  Wither Cloak Sword,  Adaptive Blade (when Tank in Dungeons), or  Astraea)
• Using Accessories (ex: Gravity Talisman)
• Using Protection on Armor
• Equipping certain Pets
• Reforging items to certain Reforges (ex: Titanic Reforge)
• Drinking the Resistance
• Abilities such as the  Pigman Sword's Burning Souls or the  Hyperion's Wither Shield

Trivia

• When ❈ Defense approaches infinity (i.e. having the maximum defense), the damage reduction approaches 100%.
  • However, the 100% is an estimated number, due to how Effective Health is calculated.
  • To truly get infinite Effective Health, the only way is to let the naturally regenerated Effective Health outclass the ❁ Damage taken.
