Hit detection
(Currently unknown how a hit/miss is determined)
Damage Calculation
The following method is used to determine the damage of a normal attack:
1. Calculate base damage (round BaseDamage down):
BaseDamage = [(AttackerOffense * 3) - DefenderDefense] / 4
2. Get random multiplier from this table. There is a 50% chance of RandMult being negative.
| Odds | 3.9% | 7.8% | 7.8% | 7.8% | 7.8% | 7.0% | 7.0% | 6.3% | 6.3% | 5.5% | 4.7% | 4.7% | 3.9% | 3.1% | 3.1% | 2.3% | 2.3% | 1.6% | 1.6% | 1.6% | 0.8% | 0.8% | 0.8% | 0.8% |
| RandMult | 0x00 | 0x01 | 0x02 | 0x03 | 0x04 | 0x05 | 0x06 | 0x07 | 0x08 | 0x09 | 0x0A | 0x0B | 0x0D | 0x0E | 0x0F | 0x10 | 0x11 | 0x12 | 0x13 | 0x14 | 0x15 | 0x16 | 0x17 | 0x18 |
3. Calculate final damage (round FinalDamage down):
FinalDamage = BaseDamage * (1 ± 0.1 * RandMult)
This means that any normal attack can hit for 76% to 124% of its base damage.
