====== Accuracy Mechanic ======

Accuracy is a combat mechanic in Remixed Pixel Dungeon that determines the chance to successfully hit a target with attacks. Higher accuracy increases the probability of landing hits on enemies.

==== Accuracy Formula ====
In the game's code, accuracy is calculated in the ''Char.java'' file as part of the ''attackSkill'' method:

<code java>
public int attackSkill(Char target) {
    int[] bf = {0};
    forEachBuff(b -> bf[0] += b.attackSkillBonus(this));

    int bonus = bf[0];

    float accuracy = (float) Math.pow(1.4, bonus);

    if (target == null) { // Mainly to mask bug in Remixed RPG
        target = CharsList.DUMMY;
    }

    if (rangedWeapon.valid() && level().distance(getPos(), target.getPos()) == 1) {
        accuracy *= 0.5f;
    }

    float mainAccuracyFactor = getActiveWeapon().accuracyFactor(this);
    float secondaryAccuracyFactor = getSecondaryWeapon().accuracyFactor(this);

    float skillFactor = Utils.min(20f, mainAccuracyFactor, secondaryAccuracyFactor);

    int aSkill = (int) ((baseAttackSkill + lvl()) * accuracy * skillFactor);

    GLog.debug("%s attacking %s with factor %2.2f, resulting skill %d", getEntityKind(), target.getEntityKind(), skillFactor, aSkill);

    return aSkill;
}
</code>

==== Key Factors Affecting Accuracy ====
  * **Attack Skill**: The primary factor determining hit probability
  * **Buff Bonuses**: Each bonus point increases accuracy exponentially using the formula ''Math.pow(1.4, bonus)'' (from ''RingOfAccuracy'' or similar items)
  * **Weapon Accuracy Factor**: Different weapons have different ''accuracyFactor'' values (e.g., ''RingOfAccuracy'' provides a bonus)
  * **Ranged Penalty**: When using a ranged weapon at melee distance (distance = 1), accuracy is halved (0.5f multiplier)
  * **Weapon Enchantments**: Some enchantments affect accuracy
  * **Status Effects**: Negative effects like blindness can reduce accuracy

==== Equipment with Accuracy Benefits ====
  * **[[rpd:ring_of_accuracy_item|Ring of Accuracy]]**: Increases attack skill bonus equal to the ring's level (directly improving accuracy)
  * **[[rpd:weightstone_item|Weightstone]]**: Can be used to imbue weapons with accuracy at the cost of speed
  * **Weapon Imbue ACCURACY**: Using a weightstone with the "For accuracy" option will imbue a weapon with accuracy (+1.5x multiplier)
  * **[[rpd:compound_bow_item|Compound Bow]]**: Has improved accuracy over a wooden bow at the cost of some speed

==== Related Strings ====
  * ''RingOfAccuracy_Name'': "Ring of Accuracy"
  * ''RingOfAccuracy_Info'': "This ring increases your chance to hit the enemy."
  * ''Weightstone_WndAccuracy'': "For accuracy"
  * ''CompoundBow_Info'': "Arrows launched from this compound bow deal a great amount of damage and have improved accuracy over a wooden bow at the cost of some speed."

==== Class Considerations ====
  * **Warrior**: Benefits from high accuracy to land consistent hits
  * **Mage**: Important for ensuring wand shots connect
  * **Rogue**: High accuracy helps with stealth-based attacks
  * **Huntress**: Essential for ranged weapons effectiveness
  * **Plague Doctor**: Suffers accuracy penalties without the Bone Saw equipped (string: ''HeroClass_PlagueDoctorPerks_4'')
