 +====== Evasion Mechanic ======
  
 +Evasion is a core combat mechanic in Remixed Dungeon that represents the ability to dodge incoming attacks, primarily determined by the character's defense skill.
 +
 +==== Evasion Formula ====
 +
 +The evasion calculation is part of the defense skill system in the ''Char.java'' file:
 +
 +<code java>
 +public int defenseSkill(Char enemy) {
 +    // ... base calculation ...
 +    
 +    final int[] bf = {0};
 +    forEachBuff(b -> bf[0] += b.defenceSkillBonus(this));
 +
 +    int bonus = bf[0];
 +
 +    float evasion = (float) Math.pow(1.2, bonus);
 +    if (paralysed) {
 +        evasion /= 2;
 +    }
 +
 +    // ... armor encumbrance calculation ...
 +    int aEnc = getItemFromSlot(Belongings.Slot.ARMOR).requiredSTR() - effectiveSTR();
 +
 +    if (aEnc > 0) {
 +        return (int) (defenseSkill * evasion / Math.pow(1.5, aEnc));
 +    } else {
 +
 +        if (getHeroClass() == HeroClass.ROGUE) {
 +
 +            if (getCurAction() != null && getSubClass() == HeroSubClass.FREERUNNER && !isStarving()) {
 +                evasion *= 2;
 +            }
 +
 +            return (int) ((defenseSkill - aEnc) * evasion);
 +        } else {
 +            return (int) (defenseSkill * evasion);
 +        }
 +    }
 +}
 +</code>
 +
 +==== Evasion Mechanics ====
 +
 +==== Base Evasion ====
 +  * **Calculation**: ''Math.pow(1.2, bonus)'' where bonus is the sum of all ''defenceSkillBonus'' from buffs
 +  * **Effect**: Each point of defense bonus multiplies evasion by 1.2
 +  * **Exponential Growth**: The evasion bonus increases exponentially with more defense bonuses
 +
 +==== Paralysis Effect ====
 +  * **Penalty**: When paralyzed, evasion is halved (''evasion /= 2'')
 +  * **Impact**: Reduces the character's ability to dodge attacks significantly
 +  * **Implementation**: ''if (paralysed) { evasion /= 2; }''
 +
 +==== Armor Encumbrance ====
 +  * **Calculation**: ''getItemFromSlot(Belongings.Slot.ARMOR).requiredSTR() - effectiveSTR()''
 +  * **Effect**: If armor requires more strength than available (''aEnc > 0''), evasion is reduced by ''Math.pow(1.5, aEnc)''
 +  * **Impact**: Heavy armor that requires more strength than available reduces evasion significantly
 +
 +==== Class-Specific Evasion ====
 +  * **Rogues**: Have the potential for additional evasion bonuses
 +  * **Freerunner Subclass**: When not starving and moving, evasion is doubled (''evasion *= 2'')
 +  * **Non-Rogues**: Use standard evasion calculation
 +
 +==== Evasion in Combat ====
 +  * **Hit Calculation**: ''Random.Float(attacker.attackSkill(defender)) > Random.Float(defender.defenseSkill(attacker))''
 +  * **Success**: When the defender's defense skill roll is higher, the attack is evaded
 +  * **Result**: The attack misses entirely, dealing no damage
 +
 +==== Factors Affecting Evasion ====
 +  * **Defense Skill Bonuses**: From buffs and equipment
 +  * **Paralysis Status**: Reduces evasion by 50%
 +  * **Armor Encumbrance**: Heavy armor reduces evasion when STR is insufficient
 +  * **Hero Class**: Rogues have special evasion mechanics
 +  * **Hero Subclass**: Freerunner gets double evasion under specific conditions
 +
 +==== Equipment with Evasion Effects ====
 +  * [[en:rpd:ring_of_evasion_item|Ring of Evasion]] - Provides direct evasion bonuses
 +  * [[en:rpd:armor_item|Armor items]] - May have encumbrance that affects evasion
 +  * [[en:rpd:hero_subclass|Hero subclasses]] - Some provide evasion bonuses
 +
 +==== Related Buffs ====
 +  * Any buff that implements ''defenceSkillBonus'' will affect evasion
 +  * [[en:rpd:ring_of_evasion_item|Ring of Evasion]] provides such a buff
