• Damage reducer
• Random damage

Random Damage calculation:

// TIP: You can create a "second-hpbar boss" by checking IsDefending on ScriptableObject
// So, it'll reduce every damage and the player will need to reduce its DF status

int damageReducer = victim.IsDefending ? victim.GetCurrentDefenseClamped(0) : 1;

int damage = (attackingCharacters[id] ? attacker.RandomCriticalDamage : attacker.RandomDamage) / damageReducer;

SPARE:

When this factor is below 0, the enemy becomes spareable. Only enemies can be spared, so the calculation happens in the EnemyData script as you can see below:

public float SubtractSpareFactor(int index, int value = 1) =>_runtimeCurrentSpareFactor[index] -= value;

public bool CanSpare(int index) => _runtimeCurrentSpareFactor[index] <= 0;

public override int SubtractCurrentDefense(int index, int value)
    {
        SubtractSpareFactor(index);

        return base.SubtractCurrentDefense(index, value);
    }
public override float SubtractCurrentHP(int index, float value)
    {
        if (index >= _runtimeCurrentHP.Count)
            return 0;

        float newHP = base.SubtractCurrentHP(index, value);

        Debug.Log($"HP percentage of enemy {CharacterName} is {FillHPRange(index).FromPercentage()} against {_healthPercentageSpareable} spare hp factor");
        if (FillHPRange(index).FromPercentage() <= _healthPercentageSpareable) // If the HP is below our threshold %
            SubtractSpareFactor(index, _startSpareFactor); // Then make the enemy spareable by reducing the factor by it's max

        return newHP;
    }
