The damage formula used in the game is as follows: Floor(Floor(Type Bonus * Specialty Bonus * Attack Power * Tile Bonus) * Attack / Floor(Defense * Tile Bonus)) = Damage (Floor means to drop all decimal places). Type bonus is either 0.8, 1.0, or 1.2 based upon the Virus -> Data -> Vaccine triangle. (i.e. Virus attacks a Data, the bonus is 1.2) Specialty bonus can be 0.8, 1.0, or 1.2 and is the specialty of the skill vs. the specialty of the target digimon. (i.e. A Water move would be 1.2 against a Fire digimon). Attack Power is the attack power of the move. For example, Terra Force is 60, Bolt Strike is 10, and Energy Blast is 37.5. Tile Bonus can be 0.8, 1.0, or 1.2 and is the bonus applied to the specialty of the move. If you are on a Darkness tile and use Grisly Wing, it would become 1.2. The Attack is the attack stat of the attacking digimon. The Defense is the defense stat of the defending digimon. The Tile Bonus can be 0.8, 1.0, or 1.2 and is the bonus applied to the specialty of the digimon. If the defender has a Fire specialty and is on a Fire tile, the value becomes 1.2.
