MapleStory/Formulas

Any decimal that appears within the formula's output is truncated, not rounded (i.e. 96.12 and 96.736 Damage will both be effectively 96). This is important when weighing WA versus Stats. This does not apply to defense damage percentage reduction rate, dodge chance and hit rate.
Mastery is a decimal. If you do not have any mastery skill, use your initial mastery. If you have a mastery skill, input it as a decimal and add it up with your initial mastery (such as "0.3").

Damage

Maximum (Except Xenon and Demon Avengers): $WeaponMultiplier\times (PrimaryStat\times 4+SecondaryStat)\times ATT/100$
Maximum (Xenon): $WeaponMultiplier\times PrimaryStat\times 3.5\times ATT/100$
'Maximum (Demon Avenger) ': $WeaponMultiplier\times (PrimaryStat/9+SecondaryStat)\times ATT/100$
Minimum: $MaximumDamage\times Mastery$
Maximum Possible damage range: 2,000,000 ~ 2,000,000
Maximum damage per line: 50,000,000 + Bonus Potential stat + Skill damage limit (e.g. Snipe)
Attack (ATT): $(EquipATT+PotionATT+SkillATT)\times SkillMultiplier$
Actual Skill Damage range: $DamageRange\times Skill\%\times (1+HyperSkillReinforce\%+BossDamage\%+TotalDamage\%)+FinalDamageBoost$ $DamageRange\times Skill\%\times (1+HyperSkillReinforce\%+BossDamage\%+TotalDamage\%)+FinalDamageBoost$
- All % in the above formula are written in terms of decimal.
- Boss Damage only applies when attacking boss monsters.
- Final Damage Boost means effects that add a small amount to the actual damage dealt (Example: 3 Warrior/Magician cards Deck effect, Inner Abilities, Paladin and Ice/Lightning Mage and Thunder Breaker and Blaze Wizard and Buccaneer card effect)

Critical Rate

$SkillCriticalRate+EquipmentPotentialCriticalRate+InnerPotentialCriticalRate+5\%$

Defense

Weapon Defense: $STR\times 1.2+DEX\times 0.5+LUK\times 0.5+INT\times 0.4+EquipmentWeaponDefense+SkillDefense\times (1+WeaponDefense\%InDecimal)$
Magic Defense: $STR\times 0.4+DEX\times 0.5+LUK\times 0.5+INT\times 1.2+EquipmentMagicDefense+SkillDefense\times (1+MagicDefense\%InDecimal)$

Monster's Damage

Note

All Damage reduction effect from skills and equipments are calculated after the regular defense formula.
This does not work on attacks that deals fixed damage (damage based on % of your HP, reducing HP value to 1, poison damage overtime)

Maximum monster damage dealt to you

$MonsterAttack\times [1-({\sqrt {CharacterDefense}}/200)+0.02\times (MonsterLevel-CharacterLevel)]\times (1-DamageAbosrption\%InDecimal)$ OR
$MonsterAttack-(CharacterDefense/4)+4\times (MonsterLevel-CharacterLevel)\times (1-DamageAbsorption\%InDecimal)$

Whichever's lower.

Minimum monster damage dealt to you: $MaximumMonsterDamageDealtToYou\times 0.85$
Note

If $(CharacterLevel>MonsterLevel)$ , $(MonsterLevel-CharacterLevel)=0$
If $MaximumMonsterDamageDealtToYou>MonsterAttack$ , $MaximumMonsterDamageDealtToYou=MonsterAttack$
If $MaximumMonsterDamageDealtToYou<1$ , $MaximumMonsterDamageDealtToYou=1$

Accuracy

Weapon Accuracy: $DEX\times 1.2+LUK+EquipmentAccuracy+SkillAccuracy\times (1+Accuracy\%InDecimal)$
Magic Accuracy: $INT+LUK\times 1.2+EquipmentAccuracy+SkillAccuracy\times (1+Accuracy\%InDecimal)$

Hit Rate

Hit Rate (in %): $100+{\sqrt {CharacterAccuracy}}-{\sqrt {MonsterAvoidability}}-(MonsterLevel-CharacterLevel)\times 2$

if $(100+{\sqrt {CharacterAccuracy}}-{\sqrt {MonsterAvoidability}})>100$ , $(100+{\sqrt {CharacterAccuracy}}-{\sqrt {MonsterAvoidability}})=100$ , before level difference accuracy penalty is applied.
If $HitRate>100$ , $HitRate=100\%$
In general ${\sqrt {MonsterAvoidability}}=MonsterLevel/10$ . Special cases are Zakum where ${\sqrt {MonsterAvoidability}}={\sqrt {144}}=12$ , and Pink Bean where ${\sqrt {MonsterAvoidability}}={\sqrt {625}}=25$ .

Avoidability

Weapon Avoidability: $DEX+LUK\times 2+EquipmentAvoidability+SkillAvoidability\times (1+Avoidability\%InDecimal)$
Magic Avoidability: $INT+LUK\times 2+EquipmentAvoidability+SkillAvoidability\times (1+Avoidability\%InDecimal)$

Dodge rate

Note: Skills that have its own dodge mechanism will work before the regular avoidability formula. Evasion rate boost works differently and only adds to the avoidability dodge rate.

Dodge Chance: ${\sqrt {CharacterAvoidability}}-{\sqrt {MonsterAccuracy}}-5\times (MonsterLevel-CharacterLevel)\times (1+EvasionRate\%InDecimal)$
If $CharacterLevel>MonsterLevel$ , $(MonsterLevel-CharacterLevel)=0$
and if $DodgeChance>90\%$ , $DodgeChance=90\%$

Experience

Monster level and character level difference EXP penalty: $(MonsterLevel-CharacterLevel-20)\times 5\%$

If $(CharacterLevel+20)>MonsterLevel$ $(CharacterLevel+20)>MonsterLevel$ , EXP penalty = $0\%$ $0\%$
- Maximum EXP penalty = $60\%$
EXP (killer): $MonsterEXP\times (0.2\times DamageDealt/MonsterHP+0.8\times Level/PartyLevel)\times EXPMultiplier$
EXP (leecher): $MonsterEXP\times (0.8\times Level/PartyLevel)\times EXPMultiplier$
Party Bonus EXP: $ReceivedMonsterEXP\times PartyBonusMultiplier$ $ReceivedMonsterEXP\times PartyBonusMultiplier$
- Received Monster EXP means the amount of EXP received by you after a monster is killed by your party.

Party Size	Party Bonus Multiplier
Party Size	Normal	20% bonus per extra member	50% bonus per extra member
1	0%	0%	0%
2	10%	30%	60%
3	15%	55%	115%
4	20%	80%	170%

6	30%	130%	280%

Leech condition

Party Level is calculated as the sum of the levels of all eligible members of the party. Ineligible members are excluded from all calculations, and receive no EXP. Eligible party members must meet one of the following requirements:

Do damage to the mob.
Within five levels of the mob.
Within five levels of a character in the party who meets both requirements.
Level gap between the highest levelled character and the lowest levelled character must be 40 or less. If it exceeds this gap limit, the killer gets all the EXP while the other members will not receive any leech EXP including high levelled characters who exceeded monster level. If this happens EXP is distributed solely on damage.

In certain locations, Mob EXP is increased based on the size of the party, in addition to the above party bonus. These include Lion Heart Castle, Tera Forest, Monster Park, Future Perion and many of the Area Bosses. For each additional party member after the first, Mob EXP is increased by 50%. With a full party of 6 people, each mob will give 380% total EXP. However, some of the maps only have 20% bonus per member. You will receive 230% mob EXP. Refer to the table if required. Assuming everyone in the party is the same level, they will get a percentage of the party EXP.

EXP stacking

Additive multipliers such as elven blessing is added after the multiplicative multipliers. Example: I have Holy Symbol and Level 1 Elven blessing. My EXP Multiplier will be 100% × 1.5 + 10% = 160% and not 165%

Multipliers of the same group cannot stack, so the higher multiplier will be taken(only for Group 1 and 2).

EXP rate = 100%

Group 1 (Cash shop coupons)

20% coupon = 1.2x
50% coupon = 1.5x
2x 1 hour/4 hour/1-Day special coupon = 2x

Group 2 (Free coupons)

Happy winter = 1.2x for 1 hour
Part time job: Effective rest (20/30/40/50/60 minutes) = 1.3x EXP for 20/30/40/50/60 minutes respectively.
30% monster park coupon = 1.3x for 30 minutes
Enjoyable winter = 1.5x for 30 minutes
1.5x EXP coupon from event quest = 1.5x
2x EXP coupon from event quest = 2x
Server 1.5x event = 1.5x
Server 2x event = 2x
Server 3x event = 3x

Group 3 (Skill effects)

Holy symbol = 1.21x ~ 1.50x depending on skill level
All skill special EXP effects are separate groups, so they can be stacked over one another as long as it is not the same skill. (Example: Demon Cry)

Additive

Spirit pendant = +10/20/30% (<1 hour/ 1~2 hour/> 2 hours)
Elven Blessing = +10/15/20% (Level 1/2/3)
EXP acquisition potion = +10% for 2 hours
Zero character card = +4/6/8/10% (Card rank B/A/S/SS)
Party bonus EXP:
- +10/15/20/25/30% on normal maps with 2/3/4/5/6 leechable members,
- +30/55/80/105/130% on maps with 20% party play bonus with 2/3/4/5/6 leechable members, and
- +60/115/170/225/280% on maps with 50% party play bonus with 2/3/4/5/6 leechable members.
Combo Kill = +1/1.5/3/5/8/10% EXP per monster for 1-49/50-99/100-199/200-399/400-998/999+ combo kill count.
Multi kill = +1/2/3/3.3/3.6/3.9/4.2/4.5% EXP per monster for 3/4/5/6/7/8/9/10+ Multi kill count (In other words, killing 3/4/5/6/7/8/9/10+ monster within an attack skill.)

Combo Kill, Multi Kill

Combo Kill

Combo kill happens when you kill multiple monsters quickly. It activates when you kill the second monster within 10 seconds after the first monster is killed by you and it activates subsequently with more monsters getting killed. You will receive bonus EXP per monster killed based on combo kill count. Maximum combo kill count is 999. The bonus EXP received is calculated only once per killing spree, which means that if you killed 2 monster at once, the combo kill bonus will be calculated based on 2 monsters together.

Combo kill count	Bonus EXP per monster
1-49	+1%
50-99	+1.5%
100-199	+3%
200-399	+5%
400-998	+8%
999+	+10%

Multi kill

Multi kill happens when you kill 3 or more monsters within a killing spree (1 skill). It ranges from 3 monsters to 10+ monsters. You also receive bonus EXP from this and the bonus is also calculated only once but the bonus is given based on the number of monsters killed.

Multi kill count	Bonus EXP per monster
3	+1%
4	+2%
5	+3%
6	+3.3%
