MapleStory/Maple Union

Maple Union is an account growth system that allows all characters to grow upon one another (just like link skills but affects all characters). The stats that are obtained depends on the level of the supplying character as well as the sum of levels of all characters in that account for that world.

Union Ranks
There are a total of 20 ranks. To increase your rank, you need a certain number of Union Coins and to have a minimum level sum. Increased ranks will let you place more Attackers inside the Uniom Board as well as to let you place the attackers at the outer areas (provided the pieces are connected to the middle)

You must have at least 500 level sum to start a Union. Union is started for free.

Level Sum is denoted as the sum of all characters in that account in that world. However, in some cases, that character will not be counted:
 * Non-Zeroes level 59 or less (Minimum level 60 to be used as a union attacker)
 * Zeroes level 129 or less (Minimum level 130 to be used as a union attacker)
 * Duplicate Zeroes (only the highest levelled Zero will be counted towards the sum. Duplicated zeroes Level 130 or above can be used as union attackers however.)
 * Characters that are not within the highest 40 levelled characters that can be counted based on criteria above (see note, you can still use these characters as union attacker even though they are not counted to the level sum)

Although you can expand more than 40 character slots, only the highest 40 levelled characters that are eligible to be counted (excluding duplicate Zeroes), will be counted, so for maximum benefits, you need to have 40 strictly Level 250 characters (with up to 1 Zero) for Grand Master Union 5.
 * Note:

Attackers
Based on the union rank, you can place a certain number of attackers inside the Union Board.

Ranks
Each character is assigned a rank based on their level and job.
 * Non-Zeroes
 * B rank: Level 60~99
 * A rank: Level 100~139
 * S rank: Level 140~199
 * SS rank: Level 200~249
 * SSS rank: Level 250


 * Zeroes
 * B rank: Level 130~159
 * A rank: Level 160~179
 * S rank: Level 180~199
 * SS rank: Level 200~249
 * SSS rank: Level 250

Number of Attackers
Based on Union Rank, you can place a set number of attackers.

Bonus Stats
You can only get each specific job's effect once. Multiple of the same jobs can be placed as attackers but only the highest rank effect will be applied. If different jobs give the same effects, it is fine and it will stack.

Bonus Stats are applied to all characters in the account in that world only if that corresponding character is placed as an attacker. Job origins are also added for convenience in planning the grinding order to maximise EXP boosts from cash shop, it has no bearing on your Union.

Attacker Union Power
Attackers are rated based on level and Star Force. This power value refers to the Union Damage dealt by that character every 1 second. This power will never run out and will always be active regardless of situation. The resultant Union Power of the attacker is the sum of Union Power from character level and the Union Power from Star Force (only counted if added into the board)


 * Level


 * Star Force

Union Board
The Union Board is where the attackers are placed.

Board Size
The size of your board is dependent of your Union Rank. Board size is centralised towards the middle grids.

Attacker Pieces
Based on the job and attacker's rank, the pieces will be shaped differently.

Pieces can be rotated. Pieces must be connected to each other and must touch 1 of the 4 middle grids. Pieces can be overlapped but during Board Stats calculation, any layers of overlaps are all treated as 1 grid.

Each 'X' or space represents 1 grid.

Board Bonus Stats
Based on the spots covered (observed from top view), additional stats are given.
 * Inner Board (12 by 10), stats location can be changed, 15 grid per stat type, stats are affected by % increases.
 * STR (+5 per grid)
 * DEX (+5 per grid)
 * INT (+5 per grid)
 * LUK (+5 per grid)
 * HP (+250 per grid)
 * MP (+250 per grid)
 * Weapon ATT (+1 per grid)
 * Magic ATT (+1 per grid)


 * Outer Board (22 by 20, exclude inner board so total 40 grid per stat type), stats location cannot be changed, list starts from top left, clockwise
 * Abnormal Status Resistance (+1 per grid)
 * Monster EXP (+0.25% per grid)
 * Critical Rate (+1% per grid)
 * Damage to Boss Monsters (+1% per grid)
 * Stance (+1% per grid)
 * Buff Duration (+1% per grid)
 * Ignore DEF (+1% per grid)
 * Critical Damage (+0.50% per grid)

Note that assuming you have reached Grand Master Union 1 with 40 Level 200 characters, you will have 36 attackers, each attacker taking 4 grids, so total you will have 144 grids of stats.

Union Coins
Using the Attacker Union Power, your attackers are always fighting for you. While doing so, you get Union Coins.

Union Coins can be obtained by the following methods.
 * Daily Quest (2 quest: 10 + 20 coins, go into the battlefield to kill monsters to finish the quest)
 * Waiting (Every 100,000,000,000 / 100 Billion damage dealt = 1 coin)
 * Attacking (Same rates as Waiting but you can enter and damage part of the Union Boss' Health, denoted by green HP bar, purple HP bar can only be depleted using the Waiting method)

Union Coins can be used to either increase your Union Rank (assuming level sum requirement is met), or purchase useful items from the Union Coin Shop.
