These formulas can be used to theoreticaly calculate certain in-game values. Such as damage numbers and % chances/risks.
These calculations are assuming that no passive and or active evade, block or counter are being used.

Name	Constants	Formula
Skill: Minimum damage	c = weapon dependent constant. g = damage from gems.	( scale * (attack - c) + additional damage) * (target defense(stat) - penetration) * elemental damage * critical hit damage + g
Skill: Maximum damage	c = weapon dependent constant. g = damage from gems.	( scale * (attack + c) + additional damage) * (target defense(stat) - penetration) * elemental damage * critical hit damage + g
