FIGHT
The fight damage is calculated in a sequence that depends on multiple steps, using several stats from both the attacker and defender.

Step 1 - Attack force
Step1 = Attacker->power + (Attacker->level * Attacker->level >> 4)

Step 2 - Critical hit
Step2 = Step1 * (1 + (( rand(0,17) >> 4 ) << 2) )

Step 3 - Random variance
Step3 = ( Step2 * rand(128,255) >> 8 ) + 1

Step 4 - Defense
Step4 = Step3 * ((255 - Defender->defense) >> 6) + 1

Step 5 - Dodging
Step5 = Step4 * (1 - (rand(Defender->dodge, 129) >> 6))

Step 6 - Always at least 1
Damage = Step5<1 ? 1 : Step5


MAGIC
The magic damage is calculated in a sequence that depends on multiple steps, using several stats from both the attacker and defender.

Step 1 - Raw damage
Step1 = Attacker->mpower + (Attacker->level * Attacker->level >> 4) * (Magic->level + 1)

Step 2 - Critical hit
Step2 = Step1 ( 1 + ((rand(0,17) >> 4) << 2) )

Step 3 - Random variance
Step3 = ( Step2 * rand(128,257) >> 8 ) + 1

Step 4 - Defense
Step4 = ( Step3 * (255 - Defender->mdefense) >> 8 ) + 1

Step 5 - Dodging randomizer
Step5 = Step4 * ( 1 - (rand(Defender->mdodge, 129) >> 6) )

Step 6 - Always at least 1
Damage = Step5<1 ? 1 : Step5
