MapleStory/Formulas

The sections of this article detail various formulas and tables within the game.

Please keep the following in mind when calculating:

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.
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").

[edit] Damage

Maximum: $Weapon Multiplier \times (Primary Stat \times 4 +Secondary Stat) \times ATT/100$
Minimum: $Maximum Damage \times Mastery$

Maximum Possible damage: $Weapon Multiplier \times (Primary Stat \times 4 + Secondary Stats) \times ATT/100 \times skill% \times (1 + ATT%) \times (1 + Total Damage% + Boss Damage% + Hypee skill reinforcement%) \times maximum critical damage$

Attack (ATT): $(Equip ATT + Potion ATT + Skill ATT) \times Skill Multiplier$

[edit] Critical Rate

$Skills critical rate + Equipment potential or abilities critical rate + 5%$

[edit] Defense

Weapon Defense: $STR \times 1.2 + DEX \times 0.5 + LUK \times 0.5 + INT \times 0.4 + Equip DEF$
Magic Defense: $STR \times 0.4 + DEX \times 0.5 + LUK \times 0.5 + INT \times 1.2 + Equip M.DEF$

[edit] Accuracy

Weapon Accuracy: $DEX \times 1.2 + LUK + EquipACC$
Magic Accuracy: $INT + LUK \times 1.2 + EquipM.ACC$

[edit] Hit Rate

Hit Rate (in %): $100 + \sqrt{ACC} - \sqrt{Mob AVD} - (Mob LVL - LVL) \times 2$

If the number is greater than or equal 100, it means a 100% hit rate. In general $\sqrt{MobAVD} = MobLVL/10$ . Special cases are Zakum where $\sqrt{MobAVD} = \sqrt(144) = 12$ , and Pink Bean where $\sqrt{MobAVD} = \sqrt{625} = 25$ .

[edit] Avoidability

Weapon Avoidability: $DEX + LUK \times 2 + EquipAVD$
Magic Avoidability: $INT + LUK \times 2 + EquipAVD$

[edit] Experience

EXP (primary): $Mob EXP \times (0.4 \times Damage dealt / Monster HP + 0.6 \times Level / Party Level) \times Holy Symbol Multiplier$
EXP (otherwise): $Mob EXP \times (0.6 \times Level / Party Level) \times Holy Symbol Multiplier$
Party Bonus EXP: $Mob EXP \times EXP Multiplier$

Party Size	EXP Multiplier	Holy Symbol Multiplier
1	1.00	1.5
2	1.10	1.5
3	1.15	1.5
4	1.20	1.5
5	1.25	1.5
6	1.30	1.5

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 the above requirements.

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, 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.

[edit] Total SP

The total amount of SP a character will have at any level varies per job.
