In order to find these out we need to report:
Once I get these numbers, I can solve for X, for example using made up numbers: A team of Ion, Hercules, Atalanta, Aphrodite and Hermes fight mysteryman in Arena. Atlanta's frost shot does 3000 damage to enemy Hercules.
So we need to calculate final stats during battle in order to figure out how much damage frost shot derives from Atalanta's PHY ATK. Agility provides 0.1 armor and 1.4 PHY ATK per point. In battle, Atalanta has 2330 PHY ATK and enemy Hercules has (200-30+(0.1*200))=190 Armor.
This leads to the equation: 94 percent of the quantity of reduction ratio times the quantity of 2330 PHY ATK times X plus the flat 500 damage from frost shot equals 3000 physical damage.
In this virtual situation, each point of physical attack (PHY ATK) contributes 2 points of damage for Atlanta's Frost Shot on the enemy Hercules.
NB: This situation is made up as an example how physical attack and magic attack ratios are calculated
