{|{{prettytable|notwide=1}}

Arcane Force can be obtained from:
*Arcane Symbols: +10 per Arcane Symbol Level equipped and +20 per Unique Arcane Symbol equipped
*Certain event expirable overhead titles and skills
*[[MapleStory/Hyper Stats#Arcane Force Increase|Hyper Stats]]: +5~+100
*[[MapleStory/Guild skills|Guild Skill]]: +15~+30
However, arcane force not from arcane symbols are only applied to the penalties/advantages in arcane river maps and nothing else that uses arcane force.

===Arcane Symbols===
Arcane Symbols can be leveled up to give more Arcane Force by equipping duplicated Arcane Symbols. Arcane Symbols can be obtained from different ways.
*Vanishing Journey: Daily Quests, Erda Spectrum and Monster Drops in Vanishing Journey/Reverse City
*Chu Chu Island: Daily Quests, Hungry Muto and Monster Drops in Chu Chu Island/Yum Yum Island
*Lachelein: Daily Quests, Dream Defender and Monster Drops in Lachelein
*Arcana: Daily Quests, Spirit Saviour and Monster Drops in Arcana
*Morass: Daily Quests and Monster Drops in Morass
*Esfera: Daily Quests and Monster Drops in Esfera
Note: Monster Drop rate is insanely low (about 1 in 20,000+ monsters at 1x drop rate for specific area symbols, and even lower for selectors). '''Symbol selectors dropped are tradable in non-Reboot worlds, and untradeable in Reboot worlds'''.

In addition, events may give out untradeable Arcane Symbol Selector coupons to exchange for '''a symbol of your choice (only the ones that you have obtained a symbol from quest are allowed to be chosen)'''

*Required number of symbols to level up: <math>SymbolLevel^2 + 11</math>
*Required mesos to level up
**Vanishing Journey: <math>10,000 \times floor[(8 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
**Chew Chew Island: <math>10,000 \times floor[(10 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
**Lacheln: <math>10,000 \times floor[(12 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
**Arcana: <math>10,000 \times floor[(14 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
**Moras: <math>10,000 \times floor[(16 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
**Esfera: <math>10,000 \times floor[(18 + 0.1 \times SymbolLevel) \times SymbolToNextLevel]</math>
Both symbols and mesos are needed to increase the symbol level.

You can use a lower growth symbol to combine with a higher growth symbol at no additional cost, but mesos used on the lower growth symbol are not refunded. This makes it possible to exceed the required symbol for the next level, and the excess is carried over (in the case of level 20, excess symbol also counts when using an Arcane Catalyst)

You may refer to this for the total meso cost in table format (credits to player whackybeanz of MapleSEA): https://whackybeanz.com/calc/symbols

For daily quest EXP, you can refer to: https://whackybeanz.com/calc/everything-exp

(Erda Spectrum, Hungry Muto and Dream Breaker EXP is excluded, EXP awarded is available once daily per area per world, not per character)

Arcane Symbols will increase your Final Stats and Arcane Force.
*All Jobs (except Xenon and Demon Avenger): 100 Final Primary Stat per 10 Arcane Force from Arcane Symbols
*Xenon: 48 Final STR, 48 Final DEX, 48 Final LUK per 10 Arcane Force from Arcane Symbols
*Demon Avenger: 2,100 Final HP per 10 Arcane Force from Arcane Symbols

====Transferring Arcane Symbols====
From the [[MapleStory/Maple Union|Union Coin Shop]], for 300 Union Coins, you can buy an Arcane Catalyst, up to 3 per character weekly '''(not available in Reboot Worlds)'''. Use it to destabilize an Arcane Symbol '''Level 2 or higher''' to turn it into an Unstable Arcane Symbol. It will have the following characteristics:
*Symbol Level drops back to Level 1
*Total Symbol EXP reduces to 80% of original, rounded up.
*Tradable within the account
Place in storage to transfer it to another character. That character must meet the following requirements to stabilise it to use that Arcane Symbol.
*Completed the corresponding town's story quests (Obtained an Arcane Symbol for that town)
*The same symbol must not exist in the same character (whether or not equipped), so the character must '''throw away existing duplicate symbols to stabilize it''' (Dream Coins, Spirit Coins, and symbol exchange coupons are allowed however).
Once stabilized, symbol becomes untradeable. '''Final Stat boost will be adjusted to match the job'''. You will then have to pay mesos to bring the Arcane Symbol back to higher levels if applicable.

The growth conversion is as follows, assuming all mesos are paid after the conversion.

==Arcane Quickpass==
At the first 6 Arcane River towns, you can talk to Spiegelmann to instantly complete daily quest by '''paying 500 Maple Points per quest, or 2,000 Maple Points per weekly special content attempt''' (however, only the maximum attempts option is available, so the service cannot be used partially). '''Quickpass cannot be used from 11.50pm to 12.30am daily'''. Arcane River progress discount will be applied to Quickpass.

'''Achievements will not be awarded for using Quickpass and only Arcane Symbols or the exchange coupons will be awarded. EXP for weekly special contents are not paid, but the daily quest EXP can still be obtained if it is not claimed yet (once per world per area daily).''' In the same way as completing the daily quest normally, a prompt is given to ask if you want to receive the EXP if available, and rejecting it will not use the chance count for EXP, but it will award only the arcane symbols or the exchange coupons.
