Elemental Mastery

See also: Damage § Elemental Reaction Damage

Elemental Mastery is an attribute that enhances Elemental Reactions.

Upon triggering an reaction, Elemental Mastery causes the following effects:

For Overloaded, Superconduct, Electro-Charged, Burning, Shattered and Swirl, reaction DMG is increased.
For Melt and Vaporize, the triggering attack damage is multiplied.
For Aggravate and Spread, an Additive Base DMG Bonus is added to the triggering attack damage.
For Crystallize, the shield's DMG absorption is increased.

Elemental Mastery Formula[]

The higher a unit's Elemental Mastery, the stronger the elemental reactions the character can release.

Graph showing the percentage bonus to Elemental Reactions based on Elemental Mastery.

The $\% \text{EM Bonus}$ is calculated depending on the reaction:

Increases damage of Vaporize and Melt by X.
Increases damage of Overloaded, Superconduct, Electro-Charged, Burning, Shattered, Swirl, Bloom, Hyperbloom, and Burgeon by Y.
Increases the DMG Bonus provided by Aggravate and Spread by Z.
Increases damage absorption of shields created by Crystallize by W.
Where X, Y, Z, and W are:^[1]^[2]^[3]

X = 2.78 \times \frac{\text{EM}}{\text{EM} + 1400} \times 100 \%

Y = 16 \times \frac{\text{EM}}{\text{EM} + 2000} \times 100 \%

Z = 5 \times \frac{\text{EM}}{\text{EM} + 1200} \times 100 \%

W = 4.44 \times \frac{\text{EM}}{\text{EM} + 1400} \times 100 \%

These values are used in damage or shield health calculations as:

\text{Reaction Multiplier} = (1 + \% \text{EM Bonus} + \% \text{Reaction Bonus})
