DEF

Defense, abbreviated in-game as DEF, is a measure of how much incoming damage to a character or enemy is reduced.
The higher the defense, the less damage is taken from attacks. Defense can be modified by:
*raising your character level
*equipping artifacts or weapons that provide DEF or DEF% attributes
*certain character talents or constellations
*food items that provide a temporary defense boost when consumed
*other environmental factors such as Infusion Stones
Defense is calculated as:
:\text{DEF} = \text{DEF}_\text{Character} \times (1 + \% \text{DEF Bonus}) + \text{DEF Flat Bonus}
For both characters and enemies, defense reduces incoming damage based on this formula:NGA: [数据讨论 防御力(等级)乘区对伤害影响公式出炉——实际上等级压制与防御力是一回事！(更新完毕)]
:\text{DEF DMG Reduction}=\frac{\text{DEF}}{\text{DEF} + 5 \times \text{Level}_\text{Attacker} + 500}
The incoming damage will then be multiplied by
:\text{DEF Multiplier}=1 - \text{DEF DMG Reduction}
%DEF debuffs are applied as negative %DEF Bonuses. Note that the total %DEF Bonus cannot go lower than -90%.
==Enemy Defense==
Characters have DEF attributes based on their base stats, levels, weapons, artifacts, and any buffs (e.g., Food).
Enemy DEF is given as:
:\text{DEF}_\text{Enemy} = 5 \times \text{Level}_\text{Enemy} + 500
DEF reduces incoming damage, but its effectiveness is dependent on the attacker's level:
:\text{DEF Multiplier} = \frac{\text{Level}_\text{Character} + 100}{\text{Level}_\text{Character} + \text{Level}_\text{Enemy} + 200}
*In general this means that damage received is half (50%) of the attack power (also Incoming Damage used in the equations) at equal foe levels.
*The change in damage due to differences in level is relatively small, less than a 10% relative difference for a level difference of 20 (and far less at high levels).
For enemies with debuffed DEF:
\text{DEF Multiplier}_\text{(Debuffed)} = \frac{\text{Level}_\text{Character} + 100}
 {\left[ 1 - \% \text{ DEF Reduction} \right] \left[ 1 - \% \text{ DEF Ignored} \right] (\text{Level}_\text{Enemy} + 100) + \text{Level}_\text{Character} + 100}
*The key difference of skills that decrease or reduce DEF to the skills that ignored DEF is that the former changes the actual attribute's values, increasing all damage that factors in DEF while the latter is only applicable to a specific skill/attack of the character that triggers it.
Intermediate Equations
The DEF Multiplier formula from above:
Given the expression for damage reduction as:
\text{DEF DMG Reduction} = \frac{\text{DEF}_\text{Enemy}}{\text{DEF}_\text{Enemy} + 5 \times \text{Level}_\text{Character} + 500}
Plug in enemy defense to produce the damage reduction for enemies:
\begin{align}
\text{DEF DMG Reduction}
 &= \frac{\left[ 5 \times \text{Level}_\text{Enemy} + 500 \right]}
 {\left[5 \times \text{Level}_\text{Enemy} + 500\right] + 5 \times \text{Level}_\text{Character} + 500}
\\
 &= \frac{\text{Level}_\text{Enemy} + 100}
 {\text{Level}_\text{Enemy} + 100 + \text{Level}_\text{Character} + 100}
\\&= \frac{\text{Level}_\text{Enemy} + 100}
 {\text{Level}_\text{Enemy} + \text{Level}_\text{Character} + 200}
\end{align}
Subtract the damage reduction from 1 to get a defense multiplier for incoming damage.
\begin{align}
\text{DEF Multiplier}
 &= 1 - \text{DEF DMG Reduction}
\\
 &= 1 - \left[ \frac{\text{Level}_\text{Enemy} + 100}
 {\text{Level}_\text{Enemy} + \text{Level}_\text{Character} + 200} \right]
\\
 &= \frac{\text{Level}_\text{Character} + 100}
 {\text{Level}_\text{Enemy} + \text{Level}_\text{Character} + 200}
\end{align}
To consider debuffs that decrease an enemy's defense, multiply the enemy defense accordingly.
\begin{align}
\text{DEF}_\text{Enemy (Debuffed)}
 &= (1 - \% \text{ DEF Reduction}) \times \text{DEF}_\text{Enemy}
\\
 \text{DEF Multiplier}_\text{Enemy (Debuffed)} &= \frac{\text{Level}_\text{Character} + 100}
 {\left[ 1 - \% \text{ DEF Reduction} \right] (\text{Level}_\text{Enemy} + 100) + \text{Level}_\text{Character} + 100}
\end{align}
