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.

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

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;
}

• 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

• Ring of Accuracy: Increases attack skill bonus equal to the ring's level (directly improving accuracy)
• 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)
• Compound Bow: Has improved accuracy over a wooden bow at the cost of some speed

• 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.”

• 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)
