\[\text{Damage} =\left (\text{AttackerMag} + \text{Power} \right) \times \frac{265 - \text{TargetSpr}}{4} \times \frac{\text{Power}}{256} \times \frac{[0..32] + 240}{256}\]Demi, Percent
\[\text{Damage} = \frac{\text{AttackPower} \times \text{TargetCurrentHP}}{16}\]Demi power = 4
Percent = 15

Classic damage:

Compute crit
v1 = 255 * (RELATED_TO_CRIT_BONUS + (unsigned __int8)BCI_LUCK[208 * p_attacker_slot_id]) / 255;
Stat
LCK & SPD
magicJunctionnedValue is the junction value defined in kernel.bin for the stat.
\[\text{charaStat} = \text{CapTo255}\left( \text{charaBasedStat} + \text{charaLvl} \times \text{stat}_0 + \frac{\text{charaLvl}}{\text{stat}_1} + \text{stat}_2 - \frac{\text{charaLvl}}{\text{stat}_3} + \frac{\text{magicJunctionnedValue} \times \text{magicAmount}}{100} \right)\]STR & VIT & MAG & SPR
strBonus is 0 if we don’t compute STR
\[\text{statResult} = \frac{\text{charaLvl}^2}{\text{stat}_3}\] \[\text{statResult} = \text{CapTo255}\left( \text{charaBasedStat} + \text{strBonus} + \frac{\text{stat}_2 + \frac{\text{charaLvl} \times \text{stat}_0}{10} + \frac{\text{charaLvl}}{\text{stat}_1} - \left( \frac{\text{getLow32bit}(\text{statResult}) - \text{getHigh32bit}(\text{statResult})}{2} \right)}{4} + \frac{\text{magicJunctionnedValue} \times \text{magicAmount}}{100} \right)\]
