Physical damage

Damage
Physical	Arts	Elemental	True

Physical damage is reduced by DEF, which reduces the damage at a flat rate (e.g. 100 DEF = -100 physical damage taken), and is calculated using the following formula:

$f = [atk - (d - i_f) \times (1 - i_s) ] \times (amp \times red)$

$d = [(def + mod_1) \times (1 + b) - mod_2] \times (1 - mod_3)$

Where:

• $f$ represents the final physical damage.
• $atk$ represents ATK once all ATK buffs and multipliers are applied.
• $i_f$ represents flat DEF Ignore.
• $i_s$ represents scaling DEF Ignore.
• $d$ represents DEF once all buffs and debuffs are applied.
• $def$ represents DEF once all stage buffs and multipliers are applied.
• $mod_1$ represents the sum of flat DEF increase.
• $b$ represents the sum of all scaling DEF Buffs.
• $mod_2$ represents the sum of flat DEF decrease.
• $mod_3$ represents the product of all scaling defense Debuffs.
• $amp$ represents the sum of all physical damage amplifications.
• $red$ represents the sum of all physical damage reductions.
• The minimum value of $f$ is 5% of $atk$.
• The minimum value of $def$ is 0.

Flat defense modifiers from enemies, such as the debuff inflicted by Acid Originium Slugs are calculated before the scaling DEF increase.

For example, the damage dealt by SilverAsh under the condition stated above against a Level 1 Mephisto who is being debuffed by Pramanix's Natural Deterrent and Ifrit's Pyroclasm while his HP is below 40% (thus making him subject to the former's talent Weakening) would be calculated by the following method, assuming that both Pramanix and Ifrit is at Elite 2 and their respective skills are at Mastery 3:

$\begin{align} a = [3768 - (1000 + -300) \times (1 - 0.6)] \times 1.3 \\[2ex] a = [3768 - 700 \times 0.4] \times 1.3 \\[2ex] a = [3768 - 280] \times 1.3 \\[2ex] a = 3488 \times 1.3 \\[2ex] a = 4534,4 \end{align}$

As the result, under the above conditions and assumptions, SilverAsh's Power Strike γ will deal a whopping 4,534 damage.
